This new publication, which includes three major chapters by a number of authors from the mining industry, presents a comprehensive overview of gold mineralization in one of the classic mining districts in the Basin and Range country of the western United States. The publication is the latest in a protracted and wide-ranging collaborative investigation that documents the behavior of gold in pluton-related systems in the Battle Mountain Mining District.
The monograph includes documentation of the three-dimensional relationship between distal-disseminated Ag-Au deposits and the skarn-related, porphyry Cu environment--including revised grade-tonnage distributions for the former--as well as documentation of a complex structural imbrication in the Devonian, Mississippian, Pennsylvanian, and Permian Havallah sequence in the upper plate of the Golconda thrust and its role in the genesis of the gold deposits. It also contains a comprehensive examination of petrochemical evolution of submarine volcanic rocks in the Havallah basin. As a result, regional exploration criteria are developed for distal-disseminated Ag-Au environments and their coeval relations with Carlin-type gold deposits.
The book also includes three recently completed full-color geologic maps at 1:24,000 scale of the northern one-half of the Battle Mountain Mining District. These maps are of the Valmy, North Peak, and Snow Gulch 7 1/2 minute quadrangles.
