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 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.

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

This book was released on 2004 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reports the results of a mapping program in the vicinity of the Boston gold deposit near Hope Bay, south-west Nunavut. It first reviews the regional geology, the granitoid rocks of the Hope Bay volcanic belt, and their contact relationships with the belt. It then focusses on the geology of the deposit area, with descriptions of the rock types, the geologic structures, and the gold mineralization. Finally, implications of the findings for mineralization in other areas of the Hope Bay belt are discussed.
