Book Description
Handbook of Strata-Bound and Stratiform Ore Deposits, Volume 7: Au, U, Fe, Mn, Hg, Sb, W, and P Deposits focuses on the characteristics, properties, origins, and structures of Au, U, Fe, Mn, Hg, Sb, W, and P deposits. The selection first elaborates on gold in the Proterozoic sediments of South Africa, nature of the Witwatersrand gold-uranium deposits, and origin of Western-States type uranium mineralization. Discussions focus on tectonic conditions, sedimentation, mineralization and alteration, architecture of the Witwatersrand Basin, source of wealth in the Witwatersrand Basin, gold mineralization in South Africa, and ground-rules for gold prospecting. The text then ponders on origin of the Precambrian banded iron-formations, aspects of the sedimentary petrology of cherty iron-formation, and genetic problems and environmental features of volcanosedimentary iron-ore deposits of the Lahn-Dill Type. Concerns cover geological setting, crystallization structures, origin of cherty iron-formations, similarities and differences between banded and oolitic iron-formations, regional geologic distribution, and general diagnostic statement. The manuscript examines sedimentary phosphate deposits, ancient manganese deposits, and freshwater ferromanganese deposits. The selection is a dependable reference for researchers wanting to explore Au, U, Fe, Mn, Hg, Sb, W, and P deposits.

Book Description
The Gospel-Hump Wilderness lies in central Idaho. A mineral survey of the 206,500 acre area in Idaho County was conducted by the U.S. Geological Survey and the U.S. Bureau of Mines during 1980 to 1983. The study consisted of new geologic mapping, geochemical sampling of the wilderness and vicinity, geophysical surveying, and investigation of claim blocks in or near the wilderness. Fractures in the roof zone of plutons of the Idaho batholith host gold and silver deposits in mining districts that are contiguous with and included in the Gospel- Hump Wilderness. Subeconomic gold and silver resources are indicated and inferred at the War Eagle and Blue Jay mines (southeastern part of the area). Parts of the eastern half of the wilderness area, which are included in mining districts and which are along the trends of known mineralized fractures, have a high potential for gold and silver resources and moderate potential for copper, lead, zinc, and molybdenum resources in quartz fissure-veins. Other parts of the wilderness that have the same geologic setting have a moderate potential for gold and silver resources in undiscovered quartz veins that lie along the trend of or are parallel to known veins. The western third of the wilderness has a moderate potential for tungsten, silver, lead, copper, nickel, and possibly gold resources in skarn or metasomatic replacement deposits along thrust faults adjacent to carbonate units.
