The input of the method is a set of triangulated surfaces that are in contact along given lines and at given points. The output is a set of surfaces meshed with triangles as equilateral as possible. The method relies on a global Centroidal Voronoi optimization to place the vertices of the final surfaces combined with combinatorial considerations to either recover or simplify the surfaces, lines and points of the input model. When the final resolution is sufficient, the input contact lines and points are also contact lines and points of the final model. However, when dealing with models with complex contacts, resolution may be insufficient and instead of a refinement strategy that may lead to too many points, we propose to locally merge some features of the input model. This ability to simplify the input model is particularly interesting when the model is to be volumetrically meshed. The method is demonstrated on twelve structural models, including seven models built with an implicit modeling method, and one folded layer model affected by a discrete fracture network.

The aim of which was to investigate mineralogical evolution and element mobilization and redistribution during weathering under dry tropical climate. The weathering profile consists of four main horizons: (1) a spheroidal weathering zone constituted by a corestone shell complex, (2) a C horizon, (3) a Bw horizon and an Ah horizon. The results indicate that nontronite, a Fe-rich smectite, is the exclusive clay mineral formed in the exfoliated shells and the C horizon. It is associated with kaolinite in the upper horizons. The coexistence of these two clay minerals induced a decrease of CEC and pH which becomes neutral. The weathering index (WI) values reveal that weathering becomes more and more intensive from the corestone up to Bw horizon, which is the most weathered horizon in the weathering profile. Mass balance calculations, using Th as immobile element, indicate that Ti is quite mobile and that Al and Fe are relatively enriched at the bottom and strongly leached at the top of the profile. Alkalis and alkaline earth elements are strong leached through out the profile, except Ca which displays similar trend as Al and Fe. The same goes for LILE (Cs, Sr),TTE (Cr, Co, Ni) and HSFE (Y, Nb, Hf). In opposite, REE are depleted at the bottom and enriched in the upper horizons, with more enrichment for LREE than for HREE. It appears that weathering of greenstone belt causes a fractionation of HREE and induces a concentration of LREEs. Ce and Eu anomalies display opposite behaviour. (C) 2013 Elsevier GmbH.

Thus, the assessment of their probability of occurrence is a major challenge for risk management. From a qualitative perspective, it is known that rockfalls occur mainly during periods of rain, snowmelt, or freeze-thaw. Nevertheless, from a quantitative perspective, these generally assumed correlations between rockfalls and their possible meteorological triggering events are often difficult to identify because (i) rockfalls are too rare for the use of classical statistical analysis techniques and (ii) not all intensities of triggering factors have the same probability. In this study, we propose a new approach for investigating the correlation of rockfalls with rain, freezing periods, and strong temperature variations. This approach is tested on three French rockfall databases, the first of which exhibits a high frequency of rockfalls (approximately 950 events over 11 years), whereas the other two databases are more typical (approximately 140 events over 11 years). These databases come from (1) national highway RN1 on R union, (2) a railway in Burgundy, and (3) a railway in Auvergne. Whereas a basic correlation analysis is only able to highlight an already obvious correlation in the case of the “rich” database, the newly suggested method appears to detect correlations even in the “poor” databases. Indeed, the use of this method confirms the positive correlation between rainfall and rockfalls in the R union database. This method highlights a correlation between cumulative rainfall and rockfalls in Burgundy, and it detects a correlation between the daily minimum temperature and rockfalls in the Auvergne database. This new approach is easy to use and also serves to determine the conditional probability of rockfall according to a given meteorological factor. The approach will help to optimize risk management in the studied areas based on their meteorological conditions.", "publicationTitle": "NATURAL HAZARDS AND EARTH SYSTEM SCIENCES", "publisher": "", "place": "", "date": "2014", "volume": "14", "issue": "8", "section": "", "partNumber": "", "partTitle": "", "pages": "1953-1964", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.5194/nhess-14-1953-2014", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1561-8633", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [ "QVI3FPFF" ], "relations": {}, "dateAdded": "2014-10-23T13:10:19Z", "dateModified": "2014-10-23T13:10:19Z" } }, { "key": "V7WVFJXR", "version": 3, "library": { "type": "group", "id": 275401, "name": "Georessources", "links": { "alternate": { "href": "https://www.zotero.org/groups/georessources", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/275401/items/V7WVFJXR", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/georessources/items/V7WVFJXR", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1721057, "username": "pya", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/pya", "type": "text/html" } } }, "creatorSummary": "Kanari et al.", "parsedDate": "2014-01-10", "numChildren": 0 }, "data": { "key": "V7WVFJXR", "version": 3, "itemType": "journalArticle", "title": "Utilization of a waste from titanium oxide industry for the synthesis of sodium ferrate by gas-solid reactions", "creators": [ { "creatorType": "author", "firstName": "N.", "lastName": "Kanari" }, { "creatorType": "author", "firstName": "I.", "lastName": "Filippova" }, { "creatorType": "author", "firstName": "F.", "lastName": "Diot" }, { "creatorType": "author", "firstName": "J.", "lastName": "Mochon" }, { "creatorType": "author", "firstName": "I.", "lastName": "Ruiz-Bustinza" }, { "creatorType": "author", "firstName": "E.", "lastName": "Allaina" }, { "creatorType": "author", "firstName": "J.", "lastName": "Yvon" } ], "abstractNote": "This work is focused on the preparation of alkali ferrates, especially sodium ferrate, using ferrous sulfate as iron bearing material and chlorine as oxidant. Ferrous sulfate heptahydrate is mainly generated during titanium oxide extraction from ilmenite through the sulfate route; it is considered as a waste for this industry. Obtained alkali ferrates belong to the compounds where iron is in the rare hexavalent state and they are becoming a substance of growing importance for water treatment and industrial effluent cleaning. Two methods are developed for the ferrate synthesis. The first method consists of simultaneous reactions of two solids (iron sulfate and sodium hydroxide) and one gaseous oxidant (diluted chlorine). The second method involves a homogenous premixing of both solids prior to the oxidation by diluted chlorine. The synthesis process is performed in a rotary reactor at room temperature; however, since the overall reaction is exothermic, temperatures as high as 150 degrees C are often recorded. The effects of several parameters such as hydration extent of raw materials, Na/Fe ratio, chlorine content of the reactive gases on the sodium ferrate synthesis are investigated to determine the optimal processing conditions. The conversion efficiency of Fe(II) to Fe(VI) during the sodium ferrate synthesis reaches about 30%. (C) 2013 Elsevier B.V.

Light hydrocarbons (including CH4, C2H6, C3H8 and nC(4)H(10)) are modeled as chain molecules without multi-polar moments. The contributions of the shape of molecules and main intermolecular interactions existing in water-light hydrocarbon systems (including repulsive and attractive forces between Lennard-Jones segments, the hydrogen-bonding force and the multi-polar interaction between water molecules) to the residual Helmholtz energy were accounted for by this EOS. The adjustable parameters for the interactions of H2O-CH4, H2O-C2H6, H2O-C3H8, and H2O-nC(4)H(10) pairs were evaluated from mutual solubility data of binary water-hydrocarbon systems at vapor-liquid equilibria. Comparison with the experimental data shows this SAFT-LJ EOS can represent well vapor-liquid (and liquid-liquid) equilibria of binary water-light hydrocarbon systems over a wide P-T range. The accuracy of this EOS for mutual solubilities of methane, ethane, propane and water is within the experimental uncertainty generally. Moreover, the model is able to accurately predict the vapor-liquid equilibria and PVTx properties of multi-component systems composed of water, light hydrocarbon as well as CO2. As we know, this EOS is the first one allowing quantitative calculation of the mutual solubilities of water and light hydrocarbons over a wide P-T range among SAFT-type EOSs. This work indicates that the molecular-based EOS combined with conventional mixing rule can well describe the thermodynamic behavior of highly non-ideal systems such as water-light hydrocarbons mixtures except in the critical region for which long range density fluctuations cannot be taken into account by this analytical model.

We tested (triaxial multistep creep tests) four core samples of a cemented limestone and analyzed creep deformations, fluids chemistry, and petrographical and petrophysical properties of samples. Different flow conditions (no flow and flow through) and chemical compositions (natural meteoric water with and without phosphate ions) were considered. Our study showed that the precipitation of calcite on free pore walls of micrites blocks the microporosity between micrite crystals, thus rendering the microporosity inaccessible to fluids. Hence, the connected porosity decreased strongly after experimentation. This is due to the PSC (pressure solution creep) which is the main process implied in the porosity reduction of a carbonate rock during deep burial. The preservation of macropores during PSC allows the preservation of permeability. In addition, calcite solubility is positively dependent on mechanical parameters (axial compaction and axial stress), thus suggesting that calcite can precipitate during decompression of deep basinal fluids, resulting in changes in porosity. A comparison of experimental results with theoretical calculations showed that the integration of the PSC process into calculation databases would greatly improve the modeling of DBR.", "publicationTitle": "JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH", "publisher": "", "place": "", "date": "février 2014", "volume": "119", "issue": "2", "section": "", "partNumber": "", "partTitle": "", "pages": "984-1007", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1002/2013JB010516", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "2169-9313", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "burial diagenesis" }, { "tag": "carbonate rocks" }, { "tag": "petrophysical properties" }, { "tag": "pressure solution creep" }, { "tag": "triaxial creep tests" } ], "collections": [ "QVI3FPFF" ], "relations": {}, "dateAdded": "2014-10-23T13:10:19Z", "dateModified": "2014-10-23T13:10:19Z" } }, { "key": "AH2QUUC6", "version": 3, "library": { "type": "group", "id": 275401, "name": "Georessources", "links": { "alternate": { "href": "https://www.zotero.org/groups/georessources", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/275401/items/AH2QUUC6", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/georessources/items/AH2QUUC6", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1721057, "username": "pya", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/pya", "type": "text/html" } } }, "creatorSummary": "Bonnetti et al.", "parsedDate": "2014-03", "numChildren": 0 }, "data": { "key": "AH2QUUC6", "version": 3, "itemType": "journalArticle", "title": "Sedimentology, stratigraphy and palynological occurrences of the late Cretaceous Erlian Formation, Erlian Basin, Inner Mongolia, People's Republic of China", "creators": [ { "creatorType": "author", "firstName": "Christophe", "lastName": "Bonnetti" }, { "creatorType": "author", "firstName": "Fabrice", "lastName": "Malartre" }, { "creatorType": "author", "firstName": "Vincent", "lastName": "Huault" }, { "creatorType": "author", "firstName": "Michel", "lastName": "Cuney" }, { "creatorType": "author", "firstName": "Sylvain", "lastName": "Bourlange" }, { "creatorType": "author", "firstName": "Xiaodong", "lastName": "Liu" }, { "creatorType": "author", "firstName": "Yunbiao", "lastName": "Peng" } ], "abstractNote": "The Erlian Basin is one of the non-marine Cretaceous basins of north-east China that developed during the late Mesozoic continental extension in eastern Asia. This basin experienced two major tectonic events: (i) a syn-rift stage that was dominated by a fluvial-lacustrine depositional environment and (ii) a post-rift stage that was dominated by a fluvial environment. A new sedimentological study performed on Erlian Formation drill cores has led to the determination of an architectural model and to the subsequent characterisation of the stratigraphic evolution of this sedimentary unit during the late Cretaceous. The palynological occurrences that were identified in samples provided a possible stratigraphical age for the Erlian Formation. Sediments of the Erlian Formation occur at the top of the Cretaceous stratigraphic column of the Erlian Basin and were deposited during the post-rift stage. Facies architecture and the ideal succession of facies that were identified for this formation exhibit two different members, both dominated by a fluvial depositional environment: (i) the lower member, which is dominated by channels of a braided river system and (ii) the upper member, which is dominated by overbank deposits. The lower member expresses a tectonically induced uplift as indicated by channels clustering under negative accommodation, whereas a period of stratigraphic base-level rise that is associated with an increase of accommodation is identified in the upper member. Therefore the Erlian Formation highlights an alternation of short uplifts that were dominated by braided fluvial channel deposits with periods of stratigraphic base-level rise that were dominated by overbank deposits. This sedimentological architecture has significant metallogenic implications for the origin of confined permeable sandstone layers, which represent adequate host-rocks for roll front-type uranium deposits. The palynological assemblage Exesipollenites, Ulmipollenites/Ulmoideipites, Buttinia and Momipites that were recognised in two samples of the Erlian Formation has revealed a post-late Campanian age therefore more likely indicating a late Cretaceous age of deposition for the sediments of the Erlian Formation.

Their median survival is approximately 18 months. The treatment consists of surgery when possible. The role of chemotherapy and radiation therapy is controversial, especially with respect to limiting cardiac radiation dose that is theoretically incompatible with the requirement of a tumoricidal dose for sarcoma. A recent series of 124 cases of the French Sarcoma Group suggested a benefit of radiation therapy on progression-free survival. Patients and methods. - The dosimetric data of 12 patients were analyzed. Results. - There was variety in radiotherapy modalities and definition of target volumes, doses and techniques are evolving more conformal plans. Irradiation appeared feasible with conventional fractionation with respect to toxicities (although probably underestimated due to short follow-up and dismal prognosis) and previously demonstrated benefit of radiotherapy for primitive cardiac sarcomas. Conclusion. - A scheme of 45 Gy in 1.8 Gy per fraction to a preoperative volume with an additional dose of 14 Gy in 7 fractions on areas at risk or residual disease and margins 1 cm, may be proposed based on the preliminary data of this study. Intensity modulated radiotherapy with daily cone-beam CT-scanner should be evaluated. (C) 2014 Societe francaise de radiotherapie oncologique (SFRO). Published by Elsevier Masson SAS.

DM1 is caused by a dynamic and unstable CTG repeat expansion in the DMPK gene, resulting in an RNA bearing long CUG repeats (n > 50) that accumulates in nuclear foci and sequesters CUG-binding splicing factors of the muscleblind-like (MBNL) family, involved in the splicing of Tau pre-mRNA among others. However, the precise mechanism leading to Tau mis-splicing and the role of MBNL splicing factors in this process are poorly understood. We therefore used new Tau minigenes that we developed for this purpose to determine how MBNL1 and MBNL2 interact to regulate Tau exon 2 splicing. We demonstrate that an intronic region 250 nucleotides downstream of Tau exon 2 contains cis-regulatory splicing enhancers that are sensitive to MBNL and that bind directly to MBNL1. Both MBNL1 and MBNL2 act as enhancers of Tau exon 2 inclusion. Intriguingly, the interaction of MBNL1 and MBNL2 is required to fully reverse the mis-splicing of Tau exon 2 induced by the trans-dominant effect of long CUG repeats, similar to the DM1 condition. In conclusion, both MBNL1 and MBNL2 are involved in the regulation of Tau exon 2 splicing and the mis-splicing of Tau in DM1 is due to the combined inactivation of both. (C) 2014 Elsevier B.V.

They are mainly made up of Serravallian granodiorite (Oued Belif massif), Tortonian rhyodacites (Oued Belif and Haddada massifs) and cordierite-bearing rhyodacites (Ain Deflaia massif) in addition to rare Messinian basalts. They are all characterized by LILE and LREE enrichment and strong enrichment in Pb and W. The Messinian basalts, which are also enriched in LILE, exhibit transitional characteristics between calc-alkaline and alkaline basalts. Geochemical (major and trace elements) and Sr, Nd and Pb isotopic compositions indicate that: (1) granodiorite is linked to the differentiation of a metaluminous calc-alkaline magma derived from a lithospheric enriched mantle source and contaminated by old crustal materials; (2) rhyodacites result from the mixing of the same metaluminous calc-alkaline magma with variable proportions of melted continental crust. Cordierite-bearing rhyodacite, characterized by the highest Sr-87/Sr-86 isotopic ratios, is the magma comprising the highest crustal contribution in the metaluminous-peraluminous mixing and is close to the old crustal end-member; (3) late hasalts, transitional between the calc-alkaline and alkaline series, originated from an enriched mantle source at the lithosphere-asthenosphere boundary. In the Nefza mining district, magmatic rock emplacement has enhanced hydrothermal fluid circulation, leading to the deposition of polymetallic mineralizations (belonging to the Iron-Oxide-Copper-Gold and the sedimentary exhalative class of deposits, among others). Magmatic rocks are also a source for the formation of lead (and probably other metals) in these deposits, as suggested by their Pb isotopic compositions. Magmatic rock emplacement and connected mineralization events can be related to the Late Mio-Pliocene reactivation of shear zones and associated lineaments inherited from the Variscan orogeny.

Data on prenatal diagnosis, ultrasound findings, pathological features, outcomes and inheritance were analyzed. Results The mean time of prenatal diagnosis was 25.6 +/- 6 weeks of gestation. Most of the diagnoses (86.8%) were prompted by abnormal ultrasound findings [heart defects (HDs), in 83.8% of cases]. On fetal autopsy, HDs were again the most common disease feature, but thymus, kidney abnormalities and facial dysmorphism were also described. The deletion was inherited in 27% of cases. Termination of pregnancy (TOP) occurred in 68.9% of cases and did not appear to depend on the inheritance status. However, early diagnosis was associated with a higher TOP rate. Conclusion This is the largest cohort of prenatal del22q11.2 diagnoses. As in postnatally diagnosed cases, HDs were the most frequently observed abnormalities. However, thymus and kidney abnormalities and polyhydramnios should also be screened for in the prenatal diagnosis of del22q11.2. Only the time of diagnosis appeared to be strongly associated with the pregnancy outcome: the earlier the diagnosis, the higher the TOP rate.

The paragenetic sequences are compared in both aquifers to propose a diagenetic model for the Middle and Late Jurassic deposits as a whole. Petrographic (optical and cathodoluminescence microscopy), structural (fracture orientations) and geochemical (delta O-18, delta C-13, REE) studies were conducted to characterize diagenetic cements, with a focus on blocky calcite cements, and their connection with fracturation events. Four generations of blocky calcite (Cal1-Cal4) are identified. Cal1 and Cal2 are widespread in the dominantly grain-supported fades of the Middle Jurassic limestones (about 90% of the cementation), whereas they are limited in the Oxfordian because grain-supported fades are restricted to certain stratigraphic levels. Cal1 and Cal2 blocky spars precipitated during burial in a reducing environment from mixed marine-meteoric waters and/or buffered meteoric waters. The meteoric waters probably entered aquifers during the Late Cimmerian (Jurassic/Cretaceous boundary) and Late Aptian (Early Cretaceous) unconformities. The amount of Cal2 cement is thought to be linked to the intensity of burial pressure dissolution, which in turn was partly controlled by the clay content of the host rocks. Cal3 and Cal4 are associated with telogenetic fracturing phases. The succession of Cal3 and Cal4 calcite relates to the transition towards oxidizing conditions during an opening of the system to meteoric waters at higher water/rock ratios. These meteoric fluids circulated along Pyrenean, Oligocene and Alpine fractures and generated both dissolution and subsequent cementation in Oxfordian vugs in mud-supported facies and in poorly stylolitized grainstones. However, these cements filled only the residual porosity in Middle Jurassic limestones. In addition to fluorine inputs, fracturation also permitted inputs of sulphur possibly due to weathering of Triassic or Purbeckian evaporites or H2S input during Paleogene times.

In order to improve our understanding of these mechanisms, we have traced for the first time, the evolution of the eastern Paris Basin platform throughout the entire Jurassic period. This carbonate platform underwent eight successive growth and demise phases, with different depositional profiles ranging from ramps to flat-topped geometries. The eight carbonate growth periods are compared with the standard sea-level curves, local tectonic regimes and recently published oxygen-isotope and/or clay mineralogy databases. Prograding heterozoan facies along ramp profiles mark periods dominated by second-order eustatic sea-level rise, relatively cool sea surface temperatures, and mesotrophic and humid conditions (Hettangian, Pliensbachian, late Oxfordian, Tithonian). During these periods, variable detrital contents in the sedimentary succession hampered the efficiency of shallow-marine carbonate factories. Higher sea surface temperatures, oligotrophic and humid conditions associated with either eustatic sea-level rise or very high local subsidence occurred during the early Bajocian and the mid-Oxfordian. These seawater properties seem to have favoured the aggradation of scleractinian corals forming dome-shaped bioherm buildups. An oolitic and lime-mud carbonate system, deposited during the Bathonian second-order eustatic sea-level fall, is characterised by miliolid-rich micritic fades on a rimmed-ramp under stable, cooler and drier conditions. The second-order maximum flooding associated with a sea surface temperature decline and/or a seawater eutrophication caused at least five carbonate demise periods (i.e. Toarcian, earliest late Bajocian, Callovian/Oxfordian transition, earliest late Oxfordian and Kimmeridgian).

The Ianapera area is part of the Neoproterozoic Vohibory domain, which covers the northern part of the Ampanihy High-Strain Zone (HSZ), in the southwestern part of the basement. By combining Landsat 7 ETM+, airborne magnetic and radiometric data as well as available maps and data, with new field, geochemical and geochronological data in a GIS, we have updated the geological map of this region to investigate a supposed suture in this area. We suggest that the proposed suture in SW Madagascar is a NNE-SSW major lineament, rather than the 20 km-wide Ampanihy HSZ. The lineament separates the Vohibory high-pressure granulites from the older Androyan medium-pressure granulites, and can be outlined from the Ianapera area to the Ampanihy region towards the south; accordingly, we named it the Ianapera-Ampanihy Suture. Based on field, geophysical and geochemical data, we recognised a suite of granites and syenites, which we named the Ianapera suite, and a small sheet-like body of granodiorite (Bevaro granodiorite). The Ianapera suite contains the only known occurrence of corundum-bearing syenite in the Madagascar basement. These bodies were formed by two distinct episodes of felsic magmatism: respectively, high-K calc-alkaline to shoshonitic, and low-K calc-alkaline pulses. The composition, mineralogy, as well as a U-Th-Pb monazite age of 540 +/- 22 Ma, is consistent with late to post-collisional emplacement of the Ianapera suite, reinforcing the hypothesis of a suture in this area. Based on the above data, we suggest a northwards continuation of this suture in Kenya, as far as the intrusive-hosted Dusi corundum deposit (Simonet et al., 2004). The Ianapera-Ampanihy Suture could be the major tectonic boundary suggested as the eastern margin of the Mozambique belt, within the central East African Orogen. (C) 2014 Elsevier Ltd.

This variation in distance affects the intensities of the measured LIBS emission lines in non-trivial ways. To determine the behavior of a LIBS emission line with distance, it is necessary to separate the effects of many parameters such as laser energy, laser spot size, target homogeneity, and optical collection efficiency. These parameters may be controlled in a laboratory on Earth but for field applications or in space this is a challenge. In this paper, we show that carefully selected ChemCam LIBS emission lines acquired from the Martian dust can be used to build an internal proxy spectroscopic standard. This in turn, allows for a direct measurement of the effects of the distance of various LIBS emission lines and hence can be used to correct ChemCam LIBS spectra for distance variations. When tested on pre-launch LIBS calibration data acquired under Martian-like conditions and with controlled and well-calibrated targets, this approach yields much improved agreement between targets observed at various distances. This work lays the foundation for future implementation of automated routines to correct ChemCam spectra for differences caused by variable distance. (C) 2014 Elsevier B.V.

However, the extrapolation of experimental reaction rates measured at high temperature (above 200 degrees C) towards lower temperatures, as well as the interpretation of the sulphur isotopic fractionation recorded in natural samples, require an accurate description of the elementary steps controlling these reactions. We addressed this question through dedicated experiments. Based on in situ Raman spectroscopy measurements, we show that the trisulphur ion S-3(-) is the dominant intermediate sulphur valence species involved in abiogenic sulphate reduction processes initiated by H2S, over a wide range of temperature (100-350 degrees C) and solution compositions, whatever the electron donor considered. The in situ spectroscopic data reported here unambiguously demonstrate the presence of S-3(-) at temperatures as low as 100 degrees C. The presence of S-3(-) is critical to achieve rapid sulphate reduction, especially at low temperature. We propose that any dissolved constituent which decreases the dielectric constant of water, or which yields favourable S-3(-) coordination, will stabilise the trisulphur ion (thus promoting TSR) at T and pH conditions that are less extreme than previously thought. The importance of S in these processes should also be taken into account when discussing the mass-independent sulphur isotopic compositions recorded in natural and/or experimental TSR-related samples.

One of the key processes controlling diagenesis of the burial environment is Pressure Solution Creep (PSC), an efficient compaction process responsible for the evolution of porosity and permeability in many carbonate reservoirs. In this experimental study, we examine the effect of i) the presence of oil in the pore space and ii) its timing of injection on the PSC process and the petrophysical properties of a carbonate rock. The experiments were performed using a flow-through high-pressure cell, allowing the simulation of the pressure/stresses and temperature conditions of a DBR. Multi-disciplinary data (mechanical, chemical, petrographical and petrophysical) demonstrate that, without oil in the pore space, the main diagenetic process is the PSC, a process reducing by three the initial porosity but having no influence on intrinsic water permeability. An early injection of oil prior to water circulation causes the inhibition of PSC by the coating of the grains, leading to the preservation of porosity. Conversely, a late injection of oil does not preserve initial porosity. The dataset obtained from these experiments show the importance of the timing of oil charging in a reservoir in the preservation of initial porosity at great depth by the inhibition of PSC. However, the coating of grains by hydrocarbons may also inhibit further diagenetic processes leading to a creation of secondary porosity at depth. (C) 2014 Elsevier Ltd.

The injected gas mixture consists of the exhaust fumes from an oxyboiler without desulphurisation with the following mole fraction composition: CO2 = 0.82, SO2 = 0.04, O-2 = 0.04, N-2 = 0.04 and Ar = 0.06. Corresponding experiments using pure CO2 and N-2 were performed as a benchmark. The rock sample was obtained by drilling to a depth of 4600 m into a low-porosity dolostone reservoir containing micrometric to centimetric fractures in the south-west of France (northern Pyrenees). The fracture network represents the primary volume available for CO2 storage and is partly filled with dolomite separated from the rock matrix by a thin layer of calcite covering the wall rocks. Experimental reactivity of the rock was tested in 2-cm(3) batch reactors in the presence of saline water (25 g/l NaCl) and a gas phase (pure N-2, pure CO2 and gas mixture). Chemical analyses of the reacting solutions indicated that the mineralogic assemblage during exposure to pure CO2 was in equilibrium with the aqueous solution. Raman analyses of the gas phase revealed only the presence of CO2. Optical and electronic microscopy of the resultant solid phases indicated partial dissolution of carbonates and oxidation of the pyrite surfaces. In the presence of the gas mixture, important mineralogic alteration occurred together with the consumption of half of the O-2 and total consumption of the SO2. This high reactivity with the gas mixture leads to the complete dissolution of calcite and partial dissolution of dolomite and the precipitation of anhydrite and barite, particularly in the zones where the calcite was initially present. Similarly, pyrite was completely oxidised to hematite. Analyses of the rock samples indicated partial alteration of the clay minerals in the matrix to potassic beidellite in the experiment involving pure CO2 and solely to vermiculites in the gas mixture experiment. In conclusion, the presence of SO2 in the injection stream associated with the presence of O-2 results in an early strong acidification of the water, which was buffered by the significant reactivity of the carbonates (dissolution of all of the calcite and 6% of the dolomite) and partial alteration of the clay minerals (87% of illite and 100% of smectite) to vermiculites. Pyrite and aqueous Fe from clays were completely oxidised by O-2, resulting in hematite and Fe3+. The mineralogic alteration and consequent volume changes under experimental conditions led to a slight increase in the porosity of the dolomite matrix and an average pore volume loss of 11% in the fractures caused by the replacement of calcite with anhydrite. Due to its high reactivity with carbonate, SO2 can react early during the injection phase. The spatial distribution of calcite in the fractures of the reservoir has to be considered as one of the primary parameters controlling the evolution of the reservoir in terms of injectivity and petrophysical properties, particularly in the zone near the injection wellbores. The integrity of the calcite-rich caprock is, however, ensured due to its thickness (more than 1000 m) and its calcite content, which leads to pH buffering and anhydrite precipitation, which, in turn, induces a porosity reduction and a possible coating of the rock formation.

When information is scarce, incomplete, imprecise or vague, this estimate is imprecise. To represent epistemic uncertainty, possibility distributions have shown to be a more flexible tool than probability distributions. The joint propagation of possibilistic and probabilistic information can rely on more advanced techniques such as the classical random sampling of the cumulative probability distribution F and of the intervals from the possibility distributions pi. The imprecise probability P is then associated with a random interval, which can be summarized by a pair of indicators bounding it. In the present paper, we propose a graphical tool to explore the sensitivity on these indicators. This is conducted by means of the contribution to sample probability of failure plot based on the ordering of the randomly generated levels of confidence associated with the quantiles of F and to the alpha-cuts of pi. This presents several advantages: (1) the contribution of both types of uncertainty, aleatoric and epistemic, can be compared in a unique setting; (2) the analysis is conducted in a post-processing step, i.e. at no extra computational cost; (3) it allows highlighting the regions of the quantiles and of the nested intervals which contribute the most to the bounds of P. The method is applied on two case studies (a mine pillar and a steep slope stability analysis) to investigate the necessity for extra data acquisition on parameters whose imprecision can hardly be modelled by probabilities due to the scarcity of the available information (respectively the extraction ratio and the cliff geometry).

In particular, the LIBS technique is being used for the first time on another planet with the ChemCam instrument, and more than 75,000 spectra have been returned in the first year on Mars. Curiosity carries body-mounted calibration targets specially designed for the ChemCam instrument, some of which are homgeneous glasses and others that are fine-grained glass-ceramics. We present direct calibrations, using these onboard standards to infer elements and element ratios by ratioing relative peak areas. As the laser spot size is around 300 mu m, the LIBS technique provides measurements of the silicate glass compositions representing homogeneous material and measurements of the ceramic targets that are comparable to fine-grained rock or soil. The laser energy and the auto-focus are controlled for all sequences used for calibration. The univariate calibration curves present relatively to very good correlation coefficients with low RSDs for major and ratio calibrations. Trace element calibration curves (Li, Sr, and Mn), down to several ppm, can be used as a rapid tool to draw attention to remarkable rocks and soils along the traverse. First comparisons to alpha-particle X-ray spectroscopy (APXS) data, on selected targets, show good agreement for most elements and for Mg# and Al/Si estimates. SiO2 estimates using univariate cannot be yet used. Na2O and K2O estimates are relevant for high alkali contents, but probably under estimated due to the CCCT initial compositions. Very good results for CaO and Al2O3 estimates and satisfactory results for Fe are obtained. 2014 Elsevier B.V.

The intercalation mechanisms which occur during reactions between graphite and lithium-europium liquid alloys have been identified. The investigation of the experimental parameters leads to the optimized conditions to isolate europium-based graphite intercalation compounds (GICs) denoted alpha-phase and gamma-phase. The ion beam analysis has been carried out to simultaneously quantify the amount of carbon, lithium and europium in a same sample. The alpha-phase shows a homogeneous distribution of the elements laterally and in depth, with a Li0.2Eu2C6 chemical formula. The unexpected presence of lithium has been revealed in the gamma-phase but the EuC6 GIC is clearly detected, in agreement with X-ray diffraction experiments. The structural properties of Li0.2Eu2C6 have been studied and a Li-Eu-Eu-Eu-Li poly-layered sheet intercalated between graphene planes has been showed along the c-axis, with c = 3.I-C = 2400 pm. The presence of lithium allows the building of a poly-layered metallic structure leading to specific magnetic properties different from those of EuC6. In the latter case, lithium does not affect either the structural or the magnetic properties of the intercalation compound. (C) 2014 Elsevier Ltd.
