Book excerpt: The Central Manitoba mine trend is one of the most important lode gold camps in the Rice Lake greenstone-granitoid belt of the western Uchi Subprovince within the western Superior Province, Manitoba, Canada. Neoarchean host rocks consist of a south-facing volcano-sedimentary succession (2.75-2.73 Ga) intruded by voluminous gabbroic sills and tonalitic-granodioritic plutons (2.73-2.72 Ga), as well as late aplite dikes (2.73-2.72 Ga) and quartz-feldspar porphyry dikes (2.73-2.71 Ga). Five generations of deformation structures have been recognized through detailed geological mapping. The entire succession was folded during early deformation prior to rare late aplite dike emplacement. All fault-fill veins and extension veins cut all lithologic units, and are structurally governed by late conjugate shear zones. Main gold mineralization occurs within fault-fill veins hosted by west-trending steeply-dipping dextral brittle-ductile and ductile shear zones, which occur along or across contacts of metabasalt, metagreywacke and metagabbro or entirely within metagabbro. Microstructural and paragenetic analyses on main gold-bearing veins have revealed that gold is intimately associated with quartz, pyrrhotite and tellurobismuthite. Main gold introduction is interpreted to have taken place contemporaneously with pyrrhotite and tellurobismuthite deposition early during dextral shearing. The Ogama-Rockland gold deposit consists of shear zone-associated quartz veins hosted by the Ross River pluton, a ca. 2728-2724 Ma tonalitic-granodioritic intrusion in supracrustal rocks (

This book was released on 1992 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Canadian segment of the Archean Superior province is a major world source of lode gold. The gold deposits occur in or near regional transcurrent and oblique slip-shear deformation zones that comprise a conjugate set to a northwest- directed compression of the Superior province. These structures provided permeable pathways for the flow of large volumes of auriferous fluid derived from an external source. Historic gold production from the United States segment of the Superior province is modest, but the close similarity in the geologic environment of the United States and Canadian segments suggests that large gold deposits should be present in the U.S.A. An occurrence model largely based on known parameters of gold mineralization in Canada suggests that the greenstone-granite terranes of the Wawa and Wabigoon sub-provinces in the United States are favorable for important gold deposits. The model suggests that gold mineralization took place during or later than the transcurrent faulting and that it took place contemporaneously with emplacement of silica-undersaturated intrusions. The faulting occurred late in the igneous-tectonic history of the Superior province, about 2,690 Ma. Extensive, intense alteration comprising carbonitization, silicification, and sulfidization accompanied the gold mineralization. The relationships between alteration minerals and mineralized veins suggest a close temporal relationship between the alteration and gold mineralization processes. The proposed occurrence model for gold mineralization and the available data suggest that two broad regions of greenstone in the Archean Superior province in north-central United States are particularly favorable for gold deposits: (1) the Upper Peninsula of Michigan, and (2) northeastern Minnesota. The Ishpeming greenstone belt of the Wawa subprovince in Michigan contains the important Ropes deposit and several other known gold occurrences, and the Vermilion district (Wawa subprovince) in northeastern Minnesota contains highly anomalous gold in soils and minor known bedrock occurrences. Transcurrent faults in both areas should be favorable sites for gold mineralization

This book was released on 1979 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greenstone belts in the Churchill Province of northern Manitoba, of probable Aphebian age, are hosts to massive sulphide Zn + Cu deposits. Towards the southeastern end of the Rusty Lake greenstone belt, 14 miles east of Leaf Rapids, the rocks consist of a metamorphosed sequence of mafic, intermediate, and felsic volcanics and derived volcaniclastic sediments. Mapping was carried out adjacent to the Ruttan Mine for an area of roughly 4 square miles, to outline the volcanic stratigraphy. 123 samples were collected in conjunction with the mapping and chemically analyzed for major elements, Cu, Zn, and S, and were studied in thin section. Mafic flows made up a large portion of volcanic rock types (30% of map area). Felsic volcanics (dacite to rhyolite tuffs, lapilli tuffs, crystal tuffs, agglomerate, and flows) are dominantly fragmental and make up 13% of the area. Intermediate composition volcanics (andesite to dacite tuffs, lapilli tuffs, crystal tuffs, agglomerate, flows) are almost entirely fragmental and make up 7% of the map area. Volcaniclastic sediemtns (33% of area) are a complexly interstratified sequence of sandstones, siltstones, conglomerates, and debris flow breccias. The volcanics at Ruttan are geochemically similar to other PreCambrian volcanic suites. Compared with modern volcanic associations, the Ruttan volcanics most closely resemble the differentiated suites typical of modern island arcs. However, at Ruttan total Fe and MgO are significantly higher, probably as a result of alteration and metasomatism, and Na2O and K2O are lower than island arc regimes, probably an effect of PreCambrian alteration. There appears to be a somewhat higher proportion of dacite-rhyolite to andesite than in most Archean volcanic assemblages ... Exploration for massive sulphide deposits should be concentrated within differentiated basaltic to rhyolitic volcanic suites having similar lithological and geochemical characteristics as those at Ruttan.

Available in PDF, EPUB and Kindle. Book excerpt: The Metallogeny of Lode Gold Deposits: A Syngenetic Perspective is a synthesis of lode gold vein forming processes, addressing the commonality in similar worldwide deposits. The book’s empirical model incorporates widely known and accepted principles of ore deposition and shows how it applies in the volcanic-sedimentary greenstone belt environment. Several chapters detail outcrop maps and photos of field occurrences and textures. The interpretations flow directly from the authors’ field work, and are coupled with analyses of underlying physical processes. Utilizing detailed geological mapping, field work, and chemical analyses as the basis of a syngenetic formation mode, the text arms readers with the tools necessary to accurately analyze and interpret new data on the subject. This includes information on decoding the significance of asymmetry in vein formation, as well as the role of lamprophyres in gold camps, how Archean geology requires integration into a lode vein formation model, and how to develop an understanding of the worldwide applicability of gold cycles to lode vein formation and exploration and how it can be applied to deposits of all ages. Presents the first book to galvanize lode gold research into a single authoritative reference Simplifies the complexity of lode gold’s underlying processes and presents valid concepts surrounding the lode gold forming environment Features color figures, illustrations, and photos that enrich the content’s focus and aid in the retention of key concepts

Available in PDF, EPUB and Kindle. Book excerpt: This bulletin proposes a geological classification of lode gold deposits based largely on the nature of the ore and on the geological settings of the deposits. Sixteen common types of bedrock gold deposits are distinguished and their main geological attributes are summarized. These do not correspond to an equal number of genetic types; many of these deposit types represent different components of larger hydrothermal systems and are genetically related. Most of the deposit types identified are represented by at least one large example (containing over 100 tonnes of gold). Descriptions are provided of Canadian gold deposits, including Archean & Proterozoic deposits in the Canadian Shield, Late Proterozoic to Palaeozoic deposits in the Appalachian Orogen, and Mesozoic to Cenozoic deposits in the Cordilleran Orogen. The final section discusses the application of gold deposit models.

Available in PDF, EPUB and Kindle. Book excerpt: Within the last decade, the high and continuing demand for gold has prompted a global gold rush on a scale never before seen, not even in the heady days of Ballarat, California and the Yukon. Gold is being sought on every continent and, with very few exceptions, in every country around the world. Such interest and fierce competition has demanded considerable innovation and improvement in exploration techniques paralleled by a rapid expansion of the geological database and consequent genetic modelling for the many different types of gold deposits now recognized. This proliferation of data has swamped the literature and left explorationist and academic alike unable to sift more than a small proportion of the accumulating information. This new book represents an attempt to address this major problem by providing succinct syntheses of all major aspects of gold metallogeny and exploration, ranging from the chemical distribution of gold in the Earth's crust, and the hydrothermal chemistry of gold, to Archaean and Phanerozoic lode deposits, epithermal environments, chemical sediments, and placer deposits, and culminates in chapters devoted to geochemical and geophysical exploration, and the economics of gold deposits. Each chapter is written by geoscientists who are acknowledged internationally in their respective fields, thus guaranteeing a broad yet up-to-date coverage. In addition, each chapter is accompanied by reference lists which provide readers with access to the most pertinent and useful publications.
