We first give an overview of natural phenomena of structurally-controlled ore formation and the background theory and mechanisms for such controls. We then provide the results of a group of simple 2D numerical models validated through comparison with Cu-vein structure observed near the Shilu Copper deposit (Yangchun, Guangdong Province, China) and finally a case study of 3D numerical modelling applied to the Hodgkinson Province in North Queensland (Australia). Two modelling approaches, discrete deformation modelling and continuum coupled deformation and fluid flow modelling, are involved. The 2D model-derived patterns are remarkably consistent with the Cu-vein structure from the Shilu Copper deposit, and show that both modelling approaches can realistically simulate the mechanical behaviours of shear and dilatant fractures. The continuum coupled deformation and fluid flow model indicates that pattern of the Cu-veins near the Shilu deposit is the result of shear strain localization, development of dilation and fluid focussing into the dilatant fracture segments. The 3D case-study models (with deformation and fluid flow coupling) on the Hodgkinson Province generated a number of potential gold mineralization targets.", "publicationTitle": "Geoscience

Common to all samples is a new type of sinusoidal inclusions, associated with inclusion bands oriented parallel to the vein wall and inclusion trails at high angle to the vein wall.\n\nCrosscutting relationships of inclusion bands and the sinusoidal inclusions imply that inclusion bands do not reflect individual crack-seal increments. In our veins, inclusion bands are not a sufficient criterion to infer the crack-seal mechanism. Further evidence for solid inclusions not formed by the classic crack-seal mechanism is given by inclusion bands in gypsum crystals grown in soft clay.\n\nDuring incorporation, solid inclusions can become folded or boudinaged, depending on their orientation with respect to the opening direction. The complex displacement field within the vein is recorded by curved crystal fibres, which track the opening direction.\n\nBased on the arrangement of solid inclusions within the vein we suggest that our veins grew continuously during syntectonic vein formation.

Based on surface roughness characteristics of the vein wall we develop a simple model for shape-growth of crystals in a crack-seal environment which can account for both tracking and non-tracking behaviours, and propose a set of ‘tracking criteria’ for antitaxial veins.

The veins, which locally constitute a penetrative fabric element at outcrop scale, are composed mainly of calcite and have a narrow rim of quartz and chlorite. Both the calcite and quartz are generally fibrous and lattice distortion in the calcite is not commensurate with the observed degree of fibre curvature. This observation supports the popular view that curved fibres grow curved as they track the vein opening vector. It is demonstrated, however, that the curvature in the material described here is due to deformation and that the lack of strong lattice distortion is due, in part, to polygonization and to recrystallization. All observations are consistent with both the calcite and the quartz fibres having grown perpendicular to the vein walls. The chlorite orientation is controlled by the orientation of mica grains in the country rock. In some veins, markers make it possible to define the net opening direction and, in all examples, it is demonstrated that the direction has not been tracked by the fibres. Since this conclusion may be more generally applicable, caution should be exercised in interpreting kinematics on the basis of fibre geometry. Where vein density is high, the veins and country rock screens separating them form a multilayer sequence that is folded into fairly harmonic folds. The folds appear to have a cleavage transected relationship to the regional cleavage, but the cleavage is shown to predate the folds.", "publicationTitle": "Tectonophysics", "publisher": "", "place": "", "date": "February 10, 1989", "volume": "158", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "311-333", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Tectonophysics", "DOI": "10.1016/0040-1951(89)90330-2", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/0040195189903302", "accessDate": "2016-06-20T19:39:50Z", "PMID": "", "PMCID": "", "ISSN": "0040-1951", "archive": "", "archiveLocation": "", "shortTitle": "Deformation of Crustal Rocks Curved vein fibres", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [], "relations": {}, "dateAdded": "2016-06-20T19:39:50Z", "dateModified": "2016-06-20T19:39:50Z" } }, { "key": "X5C5XNMB", "version": 39, "library": { "type": "group", "id": 318876, "name": "simon diss exchange", "links": { "alternate": { "href": "https://www.zotero.org/groups/simon_diss_exchange", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/318876/items/X5C5XNMB", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/simon_diss_exchange/items/X5C5XNMB", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/318876/items/CFHZ9G57", "type": "application/json" } }, "meta": { "createdByUser": { "id": 762791, "username": "s.virgo", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/s.virgo", "type": "text/html" } } } }, "data": { "key": "X5C5XNMB", "version": 39, "parentItem": "CFHZ9G57", "itemType": "attachment", "linkMode": "linked_url", "title": "ScienceDirect Snapshot", "accessDate": "2016-06-20T19:39:50Z", "url": "http://www.sciencedirect.com/science/article/pii/0040195189903302", "note": "", "contentType": "text/html", "charset": "", "tags": [], "relations": {}, "dateAdded": "2016-06-20T19:39:50Z", "dateModified": "2016-06-20T19:39:50Z" } }, { "key": "74VMFQV2", "version": 39, "library": { "type": "group", "id": 318876, "name": "simon diss exchange", "links": { "alternate": { "href": "https://www.zotero.org/groups/simon_diss_exchange", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/318876/items/74VMFQV2", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/simon_diss_exchange/items/74VMFQV2", "type": "text/html" } }, "meta": { "createdByUser": { "id": 762791, "username": "s.virgo", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/s.virgo", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "74VMFQV2", "version": 39, "itemType": "webpage", "title": "", "creators": [], "abstractNote": "", "websiteTitle": "", "websiteType": "", "date": "", "publisher": "", "place": "", "DOI": "", "citationKey": "", "url": "http://www.ged.rwth-aachen.de/files/publications/publication_405.pdf", "accessDate": "2016-06-20T19:39:41Z", "shortTitle": "", "language": "", "rights": "", "extra": "", "tags": [], "collections": [], "relations": {}, "dateAdded": "2016-06-20T19:39:41Z", "dateModified": "2016-06-20T19:39:41Z" } }, { "key": "7V436EMV", "version": 39, "library": { "type": "group", "id": 318876, "name": "simon diss exchange", "links": { "alternate": { "href": "https://www.zotero.org/groups/simon_diss_exchange", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/318876/items/7V436EMV", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/simon_diss_exchange/items/7V436EMV", "type": "text/html" } }, "meta": { "createdByUser": { "id": 762791, "username": "s.virgo", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/s.virgo", "type": "text/html" } } }, "creatorSummary": "Cox et al.", "parsedDate": "2001", "numChildren": 0 }, "data": { "key": "7V436EMV", "version": 39, "itemType": "journalArticle", "title": "Principles of structural control on permeability and fluid flow in hydrothermal systems", "creators": [ { "creatorType": "author", "firstName": "S.

Besonders die Einzel-Events der Crack-Seal-Prozesse wurden nur periphär behandelt. Die zentrale Hypothese dieser Arbeit besagt, dass Microveins die Grundbausteine des Crack-Seal-Prozesses sind und dass diese eine minimale Apertur besitzen. Hierfür wurden in den Bergen von Oman Proben in größtmöglichem Abstand zu makroskopischen Veins genommen. Viele dieser Proben enthalten keine makroskopischen Veins, weisen aber eine hohe Dichte an Mikroveins auf. Basierend auf einer Reihe von Kriterien, die eine Unterscheidung zwischen Veins aus einem oder mehreren Bruchereignissen ermöglichen, wurden Einzel-Event-Veins identifiziert und auf ihre Eigenschaften untersucht. Im Allgemeinen wuchs der Zement der Mikroveins epitaxial innerhalb der Brüche und wies eine gröbere Korngröße als die der umgebenden Matrix auf. Die Brüche propagierten zwischen den Körnern der Matrix, durchschlugen aber Körner, die wesentlich größer als die Korngröße der Matrix waren.
