Descriptive Mineral Deposit Models Of Metallic And Industrial Deposit Types And Related Mineral Potential Assessment Criteria

"Informed decisions concerning undiscovered mineral resources cannot be made without an understanding of the technological, environmental, or economic difficulties that might be encountered. Quantitative Mineral Resource Assessments: An Integrated Approach offers a modern quantitative assessment that explicates the diverse factors that affect mineral-related decisions, so that potential consequences can be more easily assessed, uncertainty and risk reduced, and courses of action determined without bias. The integrated approach focuses on three assessment parts and the models that support them and is designed so that consequences of alternative courses of action can be examined with respect to land use, exploration, or mineral-resource development. Drawing upon newly developed deposit density models, frequency distributions, and previously unpublished experiments, the book provides an essential and practical approach for making critical decisions." "Written for governmental and industrial policy makers, managers of exploration, planners of regional development, and similar decision makers, the book brings together for the first time the widely scattered literature on the subject. It also captures the necessary ingredients of the diverse disciplines of economic geology, statistics, mineral economics, and geology that are an integral part of quantitative mineral resource assessments. With this wealth of information, the book will serve not only as a guide for professionals but also as a comprehensive reference for those studying or researching mineral resources."--BOOK JACKET.

This history of placer mining of the gold deposits of east central Alaska, near the town of Circle, covers its development from 1893 to date and includes a summary of the regional geology and of the gravels of each creek.

Documents the mineral potential evaluation procedure that the Ontario Geological Survey has developed and implemented for participation in land use planning assessments in areas where potentially conflicting land use activities have been or may be proposed. The procedure is also recommended for use by geological consultants performing mineral potential evaluations for municipalities and land use agencies. The procedure involves a subjective ranking of the mineral potential using objective, defined criteria. The region to be assessed is subdivided on the basis of geologic and metallogenic parameters, and the areas are ranked with respect to the occurrence of specific deposit types. The applicable geological, geophysical and/or geochemical, and economic criteria for each deposit type are each subjectively ranked and the ratings are combined in an overlapping circle scheme. Concludes with discussion of how the evaluation methodology can assist with the consideration of provincial interests in the municipal land use planning process under the 1990 Planning Act.
