Book Description
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.

Book Description
Presents results of 1999 field studies focusing on the structure & stratigraphy within the Wallace Lake greenstone belt of east central Manitoba. The stratigraphic results involve redefinition of some of the sequences previously described in the belt and the introduction of new stratigraphic nomenclature. The nature of the contact between stratigraphic assemblages, and the internal stratigraphy of these assemblages, is then presented. This is followed by a discussion of the stratigraphic position of various komatiitic units found in the belt. The final sections describe the geochemistry of the volcanic rocks and the structural history of the greenstone belt.

Geological Classification of Canadian Gold Deposits

Category : Geology

Pages : 116
Book Description
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.
