Download or read book Geological Classification of Canadian Gold Deposits written by Knud Howard Poulsen and published by . This book was released on 2000 with total page 116 pages. 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.

This book was released on 2009 with total page 872 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Barry gold deposit is an example of an Archean greenstone-hosted lode gold deposit located in the Urban-Barry greenstone belt in the Abitibi subprovince of Québec, Canada. Auriferous zones are spatially associated with NE-trending ductile shear zones with moderate south-easterly dip. Gold mineralization occurs within albite-carbonate-quartz veins that are straight N64°E/64°SE and folded N20°E/60°SE and within the surrounding carbonate-quartz-pyrite and locally biotite-carbonate alteration zones of the host mafic volcanic rocks. The deposit has gold resources indicated at 52,300 oz (385,000 mt at 4.23 g/t Au) and inferred at 126,600 oz (966,000 mt at 4.07 g/t Au). The host mafic volcanic rocks are part of the 2717 Ma Macho Formation that exhibit a geochemical signature transitional between mid-ocean and island arc. They are cut by pre-ore diorite, pre- and post-ore quartz-feldspar porphyry (QFP), and quartz monzonite dikes and plugs interpreted to have formed in a volcanic arc to syn-collisional setting. The auriferous veins comprise 5-15% volume of the mafic volcanic rocks, are 1-5cm wide, and locally pinch and swell or are boudinaged. Although the volcanic units strike N55-60°E and dip 40°SE, the ore envelope (>2 g/t Au) is constrained from surface to 30m depth in an antiformal shape. Free gold is found in albite-carbonate-quartz veins, syn-mineralization altered host rocks, and locally within quartz veins cutting early QFP dikes. The timing of gold mineralization at the Barry deposit is well constrained by U-Pb zircon dating of pre-mineralization diorite and post-mineralization QFP dikes. Analyses of single zircon grains by thermal ionization mass spectrometry (TIMS) give concordant and overlapping data with indistinguishable ages, yielding an average age of 2697 " 0.6 Ma that is interpreted as the age of gold mineralization at the Barry deposit. This date indicates that gold mineralization was coeval with regional deformation and magmatism, and is, to our knowledge, the most precise age yet established for Archean lode gold mineralization. This confirms that the Barry lode gold deposit formed during an earlier, pre-2686, deformational period in the late Archean, similar to what was documented in the Kiena, Norlartic and Siscoe (Main Zone) mines in the Southern Abitibi greenstone belt.

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

Book excerpt: Gold deposits in the Timmins, Ontario area are spatially associated with carbonate alteration zones. However, not all carbonate alteration zones host gold mineralization, making it necessary for prospectors to be able to discriminate between metalliferous and barren carbonate alteration zones. To this end, an investigation of the carbonate alteration in the Timmins area was initiated in 1977 to better define the nature of the carbonate alteration, including those factors which control its distribution, and to establish geological & geochemical screening procedures for discriminating between gold-bearing & barren zones. After an introduction on the local geology, the report examines the distribution, morphology, and timing of carbonate alteration; the carbonatization environment; the significance of porphyry complexes, the origin of hydrothermal fluids, the significance of ultramafic flows & of the Destor-Porcupine Fault. Finally, gold exploration criteria are outlined and a multi-element trace element screen is proposed.

Download or read book Recent Advances in Understanding Gold Deposits written by T. Torvela and published by Geological Society of London Special Publications. This book was released on 2022-12-06 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gold occurs in many settings, but the dynamic nature of Earth’s crust means overlapping and overprinting deposit styles are common. Characterization of mineralization from an early stage becomes important, particularly where the mineralization is complex, in order to maximize exploration and project development success and mining productivity. Various techniques are used at different stages of a project to characterize gold deposits. This Special Publication offers a cross-section of some specific techniques used to investigate a variety of gold deposit types. The papers highlight both the breadth of the available techniques and their utility in deposit characterization, but also the many significant remaining questions and problems related to the exploration and research of gold deposits. Several papers include suggestions of avenues for fruitful further research, including a paper discussing a new approach to classifying orogenic gold deposits, and a paper describing archaeological applications of natural gold analyses.
