Book Description
The unifying theme to the papers in this volume is that they deal with economic accumulations of sulfide minerals which, together with their host rocks, have been affected to varying degrees by regional metamorphism. The principle sulfide deposit types discussed are stratabound ZnCuPbAgBa deposits in regionally metamorphosed terranes which occur in a diverse variety of host lithologies. In addition other interesting deposit types are discussed and examples are presented from various parts of the world. The topics treated in this volume are: the interaction of sulfide minerals with their host rocks during regional metamorphism; the quantitative interpretation of P-T-time histories of regional metamorphism in which both sulfide and silicate phase relations must be considered together in order to meaningfully interpret the metamorphic history; the question of how to identify progenitors of rocks modified by tectonic and metamorphic processes and the implications of these studies; developing future exploration strategies for massive sulfide deposits in meatmorphic terranes.

Book Description
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. BIF-hosted gold deposits represent a key exploration target in Precambrian rocks in Canada. During the past century, over 4.1 million oz gold have been produced from several mines in the Beardmore-Geraldton area, north-central Ontario. The main goals of this project are to: 1-determine the key geological and structural parameters that control the distribution, geometry and genesis of the BIF-hosted gold deposits in the area; 2-Determine the characteristics and geochemical signature of the gold mineralisation and the associated hydrothermal alteration; and 3-Help the industry finding new gold resources.

Category : Science
Languages : en
Pages : 850
Book Description
This book is the first comprehensive compilation of data and ideas relating to the origin, evolution, and significance of the world's greenstone belts, and includes contributions from over 100 experts. In the first of two parts, reviews are presented on broad topics relating to the geology of greenstone belts and their surroundings, covering mainly post-1980 research. These include: historical, sedimentologic, volcanic, structural, metamorphic, metallogenic, and thermal aspects; summaries of mafic/ultramafic magnetism, strain, fluids, geophysics and deep structures; relations with associated granitoids, tectonic evolution, and geochronology; and field relationships. The second part takes a more focused look at the geology of specific cratons and individual greenstone belts worldwide, including Archaean, Proterozoic, and Phanerozoic examples. Detailed geologic maps on large and small scales, extensive tabulations of data, and short written summaries of the salient features are included for all belts. The book will be a valuable reference tool for academic and industrial researchers, students, explorationists, and anyone interested in the evolution of Earth processes over geologic time.

Book Description
La province de Pataz au Nord-Pérou est la plus septentrionale des ceintures paléozoïques d'or, antimoine et tungstène orogéniques (mésothermales) de la Cordillère Orientale des Andes Centrales. Longue de plus de 160 km, elle est connue pour ses veines épigénétiques de quartz aurifères riches en sulfures (ressource : 40 millions d'onces d'or). Les minéralisations, datées à ~314 Ma, sont localisées dans des fractures inverse-décrochantes dextres et d'extension le long des marges et à l'intérieur du batholite de Pataz (329 Ma) et dans les roches métasédimentaires avoisinantes. L'intrusion hôte n'exerce qu'un rôle passif dans leur genèse et fonctionne uniquement comme un réceptacle structural très favorable. La minéralisation est temporellement liée à un stade d'exhumation du bâti et à l'addition d'un flux de chaleur dans une croûte épaissie. Le piégeage de l'or au contact des sulfures microfracturées interviendrait à 5-10 km de profondeur par dilution d'un fluide salin précoce par des eaux superficielles.
