A hydro-fracturing index accounting for the stress and the geomechanical constraints in the ore-series was estimated and seems to correlate with the presence of Cu-sulfides within the Kupferschiefer.", "series": "", "seriesNumber": "", "volume": "", "numberOfVolumes": "", "edition": "", "date": "2013", "publisher": "Sgu-Sveriges Geologiska Undersokning-Geology Survey Sweden", "place": "Uppsala", "originalDate": "", "originalPublisher": "", "originalPlace": "", "format": "", "numPages": "", "ISBN": "978-91-7403-207-9", "DOI": "", "citationKey": "", "url": "", "accessDate": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "ISI Web of Knowledge", "callNumber": "", "rights": "", "extra": "WOS:000337983900020", "tags": [ { "tag": "Late Cretaceous-Early Paleocene uplifting", "type": 1 }, { "tag": "Restoration", "type": 1 }, { "tag": "age", "type": 1 }, { "tag": "hydro-fracturing", "type": 1 }, { "tag": "inversion", "type": 1 }, { "tag": "kupferschiefer mineralization", "type": 1 }, { "tag": "polish", "type": 1 }, { "tag": "sediment-hosted ore-deposits", "type": 1 }, { "tag": "system", "type": 1 } ], "collections": [ "ZD3XR3P7" ], "relations": { "owl:sameAs": "http://zotero.org/groups/265522/items/AIES7J99" }, "dateAdded": "2014-08-21T10:39:09Z", "dateModified": "2014-08-21T10:39:09Z" } }, { "key": "2W7VA6ZJ", "version": 17, "library": { "type": "group", "id": 273297, "name": "OTELo", "links": { "alternate": { "href": "https://www.zotero.org/groups/otelo", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/273297/items/2W7VA6ZJ", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/otelo/items/2W7VA6ZJ", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1894326, "username": "Villieras", "name": "frederic villieras", "links": { "alternate": { "href": "https://www.zotero.org/villieras", "type": "text/html" } } }, "creatorSummary": "Eglinger et al.", "parsedDate": "2013", "numChildren": 0 }, "data": { "key": "2W7VA6ZJ", "version": 17, "itemType": "book", "title": "The synmetamorphic uranium deposits in high-grade Neoproterozoic rocks in the Lufilian belt, Domes region, Zambia", "creators": [ { "creatorType": "author", "firstName": "Aurelien", "lastName": "Eglinger" }, { "creatorType": "author", "firstName": "Alexandre", "lastName": "Tarantola" }, { "creatorType": "author", "firstName": "Olivier", "lastName": "Vanderhaeghe" }, { "creatorType": "author", "firstName": "Anne-Sylvie", "lastName": "Andre-Mayer" }, { "creatorType": "author", "firstName": "Clement", "lastName": "Ferraina" }, { "creatorType": "author", "firstName": "Michel", "lastName": "Cuney" }, { "creatorType": "author", "firstName": "Mike", "lastName": "Richards" }, { "creatorType": "author", "firstName": "Marc", "lastName": "Brouand" }, { "creatorType": "editor", "firstName": "E.", "lastName": "Jonsson" } ], "abstractNote": "The Pan-African Lufilian belt, in the Democratic Republic of Congo and Zambia, is known for its world-class copper and cobalt deposits. In addition, the Lufilian belt hosts several uranium occurrences localized within deformed siliciclastic rocks of the basal Neoproterozoic Katanga Supergroup. The western part of the Domes region, in the internal zone of the orogenic belt, is characterized by metamorphism reaching upper amphibolite grade. Several uranium occurrences are described from this area, along the contact between sheared metasediments of the Lower Roan Group and the gneissic-migmatitic basement. The host rocks are kyanite micaschists and ore minerals are represented by uraninite and brannerite associated with rutile, molybdenite and graphite. New U-Pb isotopic ages on uraninite at ca. 530 Ma were obtained using in-situ SIMS analyses. Conventional rutile and graphite thermometers yielded a temperature for uranium oxide crystallization at ca. 600-630 degrees C. Fluid inclusion study indicates two potential uranium-bearing fluid events, described as synto late-orogenic. These fluids, with H2O-N-2-H-2-CaCl2-NaCI and H2O-CO2-CO-CaCl2-NaCI compositions, are characterized by a high salinity (respectively, 31-40 wt% CaCl2, 13-27 wt% NaCI and > 35 wt% NaCleq) and a high homogenization temperature (> 350 degrees C). These metamorphic fluid circulation events are associated with pervasive Ca and Na-Ca (scapolitization) alterations coring the gneissic-migmatitic domes. We propose that uranium was leached from U-rich minerals by metamorphic brines during this hydrothermal event and deposited within the kyanite micaschist outcropping around the gneissic-migmatitic domes.", "series": "", "seriesNumber": "", "volume": "", "numberOfVolumes": "", "edition": "", "date": "2013", "publisher": "Sgu-Sveriges Geologiska Undersokning-Geology Survey Sweden", "place": "Uppsala", "originalDate": "", "originalPublisher": "", "originalPlace": "", "format": "", "numPages": "", "ISBN": "978-91-7403-207-9", "DOI": "", "citationKey": "", "url": "", "accessDate": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "ISI Web of Knowledge", "callNumber": "", "rights": "", "extra": "WOS:000337983900399", "tags": [ { "tag": "Lufilian belt", "type": 1 }, { "tag": "Metamorphism", "type": 1 }, { "tag": "P-T-t path", "type": 1 }, { "tag": "arc", "type": 1 }, { "tag": "congo", "type": 1 }, { "tag": "evolution", "type": 1 }, { "tag": "fluid inclusions", "type": 1 }, { "tag": "mineralization", "type": 1 }, { "tag": "northwestern zambia", "type": 1 }, { "tag": "orogen", "type": 1 }, { "tag": "rutile", "type": 1 }, { "tag": "syn- to late-orogenic", "type": 1 }, { "tag": "uranium oxide", "type": 1 }, { "tag": "uranium source", "type": 1 }, { "tag": "zone", "type": 1 } ], "collections": [ "ZD3XR3P7" ], "relations": { "owl:sameAs": "http://zotero.org/groups/265522/items/HHP3FVJP" }, "dateAdded": "2014-08-21T10:39:09Z", "dateModified": "2014-08-21T10:39:09Z" } }, { "key": "P4RGAJI8", "version": 17, "library": { "type": "group", "id": 273297, "name": "OTELo", "links": { "alternate": { "href": "https://www.zotero.org/groups/otelo", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/273297/items/P4RGAJI8", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/otelo/items/P4RGAJI8", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1894326, "username": "Villieras", "name": "frederic villieras", "links": { "alternate": { "href": "https://www.zotero.org/villieras", "type": "text/html" } } }, "creatorSummary": "Bonnetti et al.", "parsedDate": "2013", "numChildren": 0 }, "data": { "key": "P4RGAJI8", "version": 17, "itemType": "book", "title": "The Bayinwula roll front-type uranium deposit, Erlian Basin, NE China", "creators": [ { "creatorType": "author", "firstName": "Christophe", "lastName": "Bonnetti" }, { "creatorType": "author", "firstName": "Michel", "lastName": "Cuney" }, { "creatorType": "author", "firstName": "Fabrice", "lastName": "Malartre" }, { "creatorType": "author", "firstName": "Raymond", "lastName": "Michels" }, { "creatorType": "author", "firstName": "Sylvain", "lastName": "Bourlange" }, { "creatorType": "author", "firstName": "Xiaodong", "lastName": "Liu" }, { "creatorType": "author", "firstName": "Yunbiao", "lastName": "Peng" }, { "creatorType": "author", "firstName": "Jianxing", "lastName": "Yang" }, { "creatorType": "editor", "firstName": "E.", "lastName": "Jonsson" } ], "abstractNote": "The Bayinwula roll front-type uranium deposit is one of the uranium deposits discovered in the Mesozoic Erlian Basin, located in NE China.

This deep-rooted structure drives the hydrothermal activity that caused the brecciation of the Oued Belif Breccia and the emplacement of two generations of shallow felsic magmatism. The matrix-supported OBB comprises clasts of altered Triassic material and others deriving from the regional substrate. Fine-grained, low-Ti, Si-Al-rich hematite (>= 20 vol. %) is the main matrix mineral, along with REE- and U-minerals. A multi-phase alteration episode (K-Fe-(Mg)-metasomatism) slightly predates the Fe-LREE-U mineralization. The major brecciation event is coeval with the mineralization event and the emplacement of the Oued Belif rhyodacite intrusion. Except for its lack of economic level Cu and Au content, the OBB shares most typical attributes of the IOCG deposits. It may therefore be classified as either an \"Iron-Oxide associated-Alkali Altered (IOAA)\" or as an \"Iron-Oxide Uranium (IOU)\" mineral system.

assemblages in both the benthic and hyporheic zones but the changes in biological attributes of invertebrate assemblages related to colmation have never been considered simultaneously for these two zones. We studied the effects of colmation on the invertebrate assemblages of three rivers, testing a priori hypotheses on the biological attributes that should be more selected in communities subjected to different levels of colmation in both zones. Only the proportion of organisms with high fecundity increased and the proportion of small-sized organisms decreased along the colmation gradient in both zones simultaneously. As expected, a higher number of traits were significantly modified with colmation in the benthic vs. hyporheic assemblages. Most of the biological attributes impaired were different in the two zones. In the benthic zone, colmation mainly selected particular physiological or trophic characteristics of species and features related to their resistance or resilience capacities. In contrast, the morphological attributes of species were much more impaired by colmation in the hyporheic zone than in the benthic zone. In clogged benthic habitats, traits seemed to be more impaired by an increase in physico-chemical constraints (e.g. the reduction of oxygen availability) and a reduction of potential exchanges (including exchanges of food resources) due to a decline in stream bed conductivity. The morphological attributes of the hyporheic species were probably more influenced by changes in interstitial space characteristics. A potential indicator of the effects of colmation on river health may be based on the functional traits of benthic communities because they (i) satisfy the WFD recommendations, (ii) respond consistently along a colmation gradient and (iii) are comparable among assemblages even across ecoregions that differ in their taxonomic composition.

They may explain why only some parts of intrusions are mineralized and why only very few intrusions host large deposits. Moreover, most of these gold deposits postdate peak regional metamorphism and were formed in zones of relatively low strain. Indeed, the efficiency of structural gold traps is highest along favourably oriented intrusion/host-rock contacts where mechanical instability maintains high permeability in the cracked thermal aureole. This may be reinforced by melt injections from an underlying root zone. We present a structural analysis of the deformation features of a granite-pluton roof; large-scale dykes and a network of gold veins are intensively developed in this roof, recording a succession of mechanical instabilities. Our gravity survey underlines the presence of a pluton feeder zone located just beneath the mineralized network. It is argued that interferences between regional stress and melt injection in the feeder zone favoured the development of the network by strain located close to the granite roof. This stresses the role of mechanical instabilities triggered by the combined effects of regional stress and melt dynamics in determining the location and size of this type of gold deposit.

It was found in the effects of a former colonial mining engineer and may have been an observed fall. The texture, mineralogy, petrography, magnetic properties and chemical and isotopic compositions are consistent with classification as a CM2 chondrite. There are similar to 45 vol.% high-temperature components mainly Type I chondrules (with olivine mostly Fa(0-2), mean Fa(0.9)) with granular textures because of low mesostasis abundances. Type II chondrules contain olivine Fa(7) to Fa(76). These are dominantly of Type IIA, but there are IIAB and IIB chondrules, II(A) B chondrules with minor highly ferroan olivine, and IIA(C) with augite as the only pyroxene. The refractory inclusions in Paris are amoeboid olivine aggregates (AOAs) and fine-grained spinel-rich Ca-Al-rich inclusions (CAIs). The CAI phases formed in the sequence hibonite, perovskite, grossite, spinel, gehlenite, anorthite, diopside/fassaite and forsterite. The most refractory phases are embedded in spinel, which also occurs as massive nodules. Refractory metal nuggets are found in many CAI and refractory platinum group element abundances (PGE) decrease following the observed condensation sequences of their host phases. Mn-Cr isotope measurements of mineral separates from Paris define a regression line with a slope of Mn-53/Mn-55 = (5.76 +/- 0.76) x 10(6). If we interpret Cr isotopic systematics as dating Paris components, particularly the chondrules, the age is 4566.44 +/- 0.66 Myr, which is close to the age of CAI and puts new constraints on the early evolution of the solar system. Eleven individual Paris samples define an O isotope mixing line that passes through CM2 and CO3 falls and indicates that Paris is a very fresh sample, with variation explained by local differences in the extent of alteration. The anhydrous precursor to the CM2s was CO3-like, but the two groups differed in that the CMs accreted a higher proportion of water. Paris has little matrix (similar to 47%, plus 8% fine grained rims) and is less altered than other CM chondrites. Chondrule silicates (except mesostasis), CAI phases, submicron forsterite and amorphous silicate in the matrix are all well preserved in the freshest domains, and there is abundant metal preserved (metal alteration stage 1 of Palmer and Lauretta (2011)). Metal and sulfide compositions and textures correspond to the least heated or equilibrated CM chondrites, Category A of Kimura et al. (2011). The composition of tochilinite-cronstedtite intergrowths gives a PCP index of similar to 2.9. Cronstedtite is more abundant in the more altered zones whereas in normal highly altered CM chondrites, with petrologic subtype 2.6-2.0 based on the S/SiO2 and Sigma FeO/SiO2 ratios in PCP or tochilinite-cronstedtite intergrowths (Rubin et al., 2007), cronstedtite is destroyed by alteration. The matrix in fresh zones has CI chondritic volatile element abundances, but interactions between matrix and chondrules occurred during alteration, modifying the volatile element abundances in the altered zones. Paris has higher trapped Ne contents, more primitive organic compounds, and more primitive organic material than other CMs. There are gradational contacts between domains of different degree of alteration, on the scale of similar to 1 cm, but also highly altered clasts, suggesting mainly a water-limited style of alteration, with no significant metamorphic reheating.

To identify the predominant processes, we focused on (i) a possible kinetic limitation by transport in biochar particles, (ii) the evolution of biochar mineral phases and (iii) the effect of biochar on soil pH. Batch experiments were conducted to measure the sorption kinetics of copper (Cu), cadmium (Cd) and nickel (Ni) and the sorption-desorption isotherms for lead (Pb), Cu, Cd, zinc (Zn) and Ni in a wood-derived biochar. Sorption data were then compared with extraction test results using biochar with one acidic and one basic soil contaminated by Zn, Cd and Pb. Kinetic results showed that biochar particle sizes controlled metal sorption rate despite a similar specific surface area, which indicated a limitation by intra-particle diffusion. Isotherms showed a partially reversible sorption to biochar following the order Pb>Cu>CdZn>Ni, which we explained primarily by the (co)precipitation of metals or their adsorption on specific biochar mineral phases. Effective metal immobilization was observed with biochar in both contaminated soils but could not be predicted from the sorption isotherms. This immobilization appeared to be governed by the soil pH increase, which induced a greater retention of metals on soil particles. Short-term effects of biochar on contaminated soils may therefore be controlled by diffusion in biochar particles and by soil alkalinization processes.", "publicationTitle": "European Journal of Soil Science", "publisher": "", "place": "", "date": "JAN 2014", "volume": "65", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "149-161", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Eur.

The large difference in mass between the two lithium isotopes (Li-6 and Li-7) has prompted biochemists to explore the metabolism of Li by using pure 6Li and 7Li labeled drugs. However, experiments were carried out at very high Li concentrations, which did not reflect natural conditions. In the present study, we consider, for the first time, the natural variations of the Li-7/Li-6 ratio in the organs and body fluids of an animal model, sheep. Each organ seems to be characterized by a specific Li isotope composition. So far, the range of the 7Li/6Li ratio in the sheep body, expressed as delta permil variations relative to the L-SVEC standard (delta Li-7), is about 40 parts per thousand, between muscles (similar to 40 parts per thousand) and kidney (similar to 0 parts per thousand). Relative to a dietary delta Li-7 value of similar to +17 parts per thousand, serum, red blood cells, muscle, liver, brain and kidney have a Li-7 enrichment of -12 parts per thousand, -14 parts per thousand, +22 parts per thousand, +5 parts per thousand, -3 parts per thousand and -15 parts per thousand, respectively. The Li isotope composition is likely to be fractionated during intestinal absorption, with a greater absorption of Li-6 relative to Li-7. According to previous conclusions obtained with Li-6 and Li-7 labeled chemicals, Li-6 appears to diffuse into erythrocytes faster than does Li-7. However, this does not hold for myocytes and hepatocytes, because these two tissues have a higher delta Li-7 level than serum. Purely diffusive isotopic fractionation would leave all organs Li-7-depleted relative to the serum, which is not the case, suggesting that active, molecule-specific, isotopic fractionation occurs in the body. Our preliminary results suggest that natural Li isotope variations can shed light on its regulation in the body, being active or passive.", "publicationTitle": "Metallomics", "publisher": "", "place": "", "date": "2014", "volume": "6", "issue": "3", "section": "", "partNumber": "", "partTitle": "", "pages": "582-586", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Metallomics", "DOI": "10.1039/c3mt00295k", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1756-5901", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "WOS:000333565800019", "tags": [ { "tag": "fractionation" }, { "tag": "mechanism" }, { "tag": "mice" }, { "tag": "phosphorylation" }, { "tag": "sheep" } ], "collections": [ "XWT9ZMKM" ], "relations": {}, "dateAdded": "2014-07-11T15:19:02Z", "dateModified": "2014-07-11T15:19:02Z" } }, { "key": "EJHABECI", "version": 14, "library": { "type": "group", "id": 273297, "name": "OTELo", "links": { "alternate": { "href": "https://www.zotero.org/groups/otelo", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/273297/items/EJHABECI", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/otelo/items/EJHABECI", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1894326, "username": "Villieras", "name": "frederic villieras", "links": { "alternate": { "href": "https://www.zotero.org/villieras", "type": "text/html" } } }, "creatorSummary": "Michel et al.", "parsedDate": "2014-01", "numChildren": 0 }, "data": { "key": "EJHABECI", "version": 14, "itemType": "journalArticle", "title": "MarcoPolo-R: Near-Earth Asteroid sample return mission selected for the assessment study phase of the ESA program cosmic vision", "creators": [ { "creatorType": "author", "firstName": "P.", "lastName": "Michel" }, { "creatorType": "author", "firstName": "M.

MarcoPolo-R was selected in February 2011 with three other missions addressing different science objectives for the two-year Assessment Phase of the Medium-Class mission competition of the Cosmic Vision 2 program for launch in 2022. The baseline target of MarcoPolo-R is the binary NEA (175706) 1996 FG3, which offers an efficient operational and technical mission profile. A binary target also provides enhanced science return. The choice of a binary target allows several scientific investigations to occur more easily than through a single object, in particular regarding the fascinating geology and geophysics of asteroids. MarcoPolo-R will rendezvous with a primitive, organic-rich NEA, scientifically characterize it at multiple scales, and return a bulk sample to Earth for laboratory analyses. The MarcoPolo-R sample will provide a representative sample from the surface of a known asteroid with known geologic context, and will contribute to the inventory of primitive material that is probably missing from the meteorite collection. The MarcoPolo-R samples will thus contribute to the exploration of the origin of planetary materials and initial stages of habitable planet formation, to the identification and characterization of the organics and volatiles in a primitive asteroid and to the understanding of the unique geomorphology, dynamics and evolution of a binary asteroid that belongs to the Potentially Hazardous Asteroid (PHA) population.

Secondary dolomitization has locally affected these mudmounds conducting to the coexistence of dolostone and limestone patches. Numerous karst cavities are preferentially developed in dolomitic intervals and are geometrically related to one or several fracture directions. These cavities, called the \"dolostone cavity type\" can be partially filled with coarse calcite and are usually bounded to the host dolostone by a calcitic transition zone which has roughly a lenticular shape. Petrographic observations, especially under cathodoluminescence, show the following sequence starting from the micro-cavities/micro-fractures network in the transition zone: 1) calcite cement in cavities, 2) dedolomite fabric, 3) host dolomite. The observed microscopic features, as well as morphological data, lead to the development of a conceptual genetic model of karst formation at macro- and microscale. In this model, first a strong dissolution of the host dolostone occurred from the fracture network thereby creating karst cavities (at macroscale) and important pervasive porosity (at microscale). Dissolution was then followed by dedolomitization in one or two-steps of the already corroded dolospar. Afterwards cementation of the residual porosity and precipitation of coarse calcite in the karst cavities occur. Even if the geological conditions under which these processes took place are not fully unraveled yet, a model that could fit with the data is presented. A discussion about the paleo-environment and paleo-hydrological conditions is settled and we also propose that the development of karst in the dolomitized mudmounds is favored by the coexistence of dolostone and limestone patches given their initial difference in porosity and competence.", "publicationTitle": "Geologica Belgica", "publisher": "", "place": "", "date": "2014", "volume": "17", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "43-51", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Geol.

The excellent agreement obtained by independent measurements proves that rheology can be used as a relevant tool to obtain information about the morphology of clay mineral particles. The fruitfulness of this approach is further evidenced by analyzing the influence of the presence of various clay minerals on the rheology of a concentrated calcareous sand.

Extensive cryptocrystalline magnesite veins and stock-work are widespread in the serpentinite sole of the New Caledonia ophiolite. Silica is systematically associated with magnesite. It is commonly admitted that Mg and Si are released during the laterization of overlying peridotites. Thus, the occurrence of these veins is generally attributed to a per descensum mechanism that involves the infiltration of meteoric waters enriched in dissolved atmospheric CO2. In this study, we investigate serpentinite carbonation processes, and related silicification, based on a detailed petrographic and crystal chemical study of serpentinites. The relationships between serpentine and alteration products are described using an original method for the analysis of micro-X-ray fluorescence images performed at the centimeter scale. Our investigations highlight a carbonation mechanism, together with precipitation of amorphous silica and sepiolite, based on a dissolution-precipitation process. In contrast with the per descensum Mg/Si-enrichment model that is mainly concentrated in rock fractures, dissolution-precipitation process is much more pervasive. Thus, although the texture of rocks remains relatively preserved, this process extends more widely into the rock and may represent a major part of total carbonation of the ophiolite.", "publicationTitle": "Contributions to Mineralogy and Petrology", "publisher": "", "place": "", "date": "JAN 2014", "volume": "167", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "952", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Contrib.

We have found that the enhanced UV emission of the young Sun triggered a peculiar atmospheric chemistry in a CH4-rich early atmosphere that resulted in the increased formation of an organic haze, similar to the preliminary results of a previous study (Ribas et al., 2010). We have investigated the interaction between this haze and noble gases photoionized by the UV light from the younger Sun. Laboratory experiments have shown indeed that ionized xenon trapping into organics (1) is more efficient that other ionized noble gases trapping and (2) results in a significant enrichment of heavy xenon isotopes relative to the light ones (e.g., Frick et al., 1979; Marrocchi et al., 2011). We find moreover preferential photoionization of xenon that peaks at an altitude range comparable to that of the organic haze formation, in contrast to other noble gases. Trapping and fractioning of ionized xenon in the organic haze could therefore have been far more efficient than for other noble gases, and could have been particularly effective throughout the Archean eon, since the UV irradiation flux from the young Sun was expected to be substantially higher than today (Ribas et al., 2010; Claire et al., 2012). Thus we suspect that the unique isotopic fractionation of atmospheric xenon and its elemental depletion in the atmosphere relative to other noble gases, compared to potential cosmochemical components, could have resulted from a preferential incorporation of the heaviest xenon isotopes into organics. A fraction of atmospheric xenon could have been continuously trapped in the forming haze and enriched in its heavy isotopes, while another fraction would have escaped from the atmosphere to space, with, or without isotope selection of the lightest isotopes. The combination of these two processes over long periods of time provides thereby a key process for explaining the evolution of its isotopic composition in the atmosphere over time that has been observed in Archean archives (Pujol et al., 2011).

The 0-D (independent of space) one-site rate-limited desorption model proposed by Ingwersen et al. (J Environ Qual 35:2055-2065, 2006) was modified. The plant sink term of the model was approximated by the biophysical equation which assumes that the leaf nickel mass is equal to the triple product of the Intact Plant Transpiration Stream Concentration Factor for Ni IPTSCFNi (xylem:solution Ni concentration ratio), Ni concentration in solution and the volume of transpired water. The model input variables were the constant mean IPTSCFNi value, determined from independent leaf Ni accumulation kinetics, and the exponential law fitting the transpiration rate kinetics. Using the best calibration, the model was validated and a sensitivity analysis was carried out thereafter. Models were formulated as sets of ordinary differential equation systems which were solved using the fourth-order Runge-Kutta method. The best model calibration was the joint parameter optimization: the two parameters of the Freundlich Ni adsorption isotherm and of the Ni desorption rate coefficient are obtained using the kinetics of Ni concentrations in the soil solutions for the reference unplanted Ni-contaminated topsoils. The model was validated reasonably well for both Ni concentration in soil solution and leaf Ni mass. The joint parameter optimization of the two parameters of the Freundlich nickel sorption isotherm and of the Ni desorption rate was successful whereas the Freundlich batch Ni sorption isotherm dramatically overestimated Ni sorption. This joint approach is therefore recommended for any plant metal uptake model. The 0-D one-site rate-limited desorption model linked to a biophysical coupled Ni and water uptake model reasonably validated the kinetics of both Ni concentration in solution and leaf Ni mass. This promising simplified model for predicting both metal concentration in solution and leaf metal mass for metal needs further validations in culture chambers and further improvements in order to use it in the field as a one-dimensional model, taking into account soil moisture dynamics.", "publicationTitle": "Plant and Soil", "publisher": "", "place": "", "date": "JAN 2014", "volume": "374", "issue": "1-2", "section": "", "partNumber": "", "partTitle": "", "pages": "131-147", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Plant Soil", "DOI": "10.1007/s11104-013-1873-z", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "0032-079X", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "WOS:000328849200010", "tags": [ { "tag": "Bioconcentration factor" }, { "tag": "Leaf nickel accumulation" }, { "tag": "Metal hyperaccumulator plants" }, { "tag": "Nickel disponibility" }, { "tag": "One-site rate-limited desorption model" }, { "tag": "commercial phytoextraction" }, { "tag": "contaminated soils" }, { "tag": "ion activity model" }, { "tag": "large-scale systems" }, { "tag": "metal hyperaccumulation" }, { "tag": "nutrient-uptake" }, { "tag": "plant uptake" }, { "tag": "sensitivity-analysis" }, { "tag": "thlaspi-caerulescens" }, { "tag": "transpiration" }, { "tag": "uncertainty analysis" } ], "collections": [ "XWT9ZMKM" ], "relations": {}, "dateAdded": "2014-07-11T15:19:02Z", "dateModified": "2014-07-11T15:19:02Z" } } ]
