Descriptive and grade-tonnage models for distal disseminated Ag-Au deposits; a supplement to U.S. Geological Survey bulletin 1693

Abstract: STRUCTURE and ZONING: Ore minerals sparsely disseminated or in stockwork of thin quartz-sulfide veins. ORE CONTROLS: Deposits commonly occur in skarn and polymetallic vein and replacement districts outboard of all other types of mineralization. Fracture permeability is the most important ore control, Primary rock permeability may be imprtant locally STRUCTURAL SETTING: Shear zones, axial plane fractures in folded rocks ORE DEPOSIT GEOMETRY: Irregular bodies, locally conformable to bedding ALTERATION: Silicific… Show more

“…However, proximity to intrusions and association of base metal-silver vein and skarn deposits with those intrusions suggests that the gold-silver deposit type is distal disseminated (Cox and Singer, 1990). The intrusionrelated Mountain Laurel Ag-(Au-Cu-Pb) and the Silver King Ag-Pb-(Au-Cu-Zn) mines are located in the vicinity of the Cobb Creek project.…”

“…Mineral deposit models covering most metallic mineral deposits have been published by the U.S. Geological Survey in two bulletins (Cox and Singer 1986;Bliss 1992). Sillitoe and Bonham (1 984) and Bonham (1 986; have published descriptive and genetic models relating to volcanic and porphyry-hosted ore deposits.…”
