by A.J. Stose and G.W. Stose, 6 x 9-inch soft-cover book, 233 pages, 61 plates include folded 41 x 40-inch color 1:62,500-scale geologic map, 12.5 x 24-inch 1:20,000-scale of Mount Rogers volcanic series, 16 x 18-inch ~1:125,000-scale mineral distribution map, 51 figures, 1957. This publication is a detailed discussion of the geology and structure of the Gossan Lead district (portions of Carroll, Grayson, Pulaski, and Wythe counties) in southwest Virginia. The area contains sedimentary and igenous early pre-Cambrian to middle Cambrian rocks which have been intensely metamorphosed. The complex is mapped as twelve rock units which are closely folded and broken by thrust faults and include cross-sections. Most of the mineral wealth of the district was derived from the mining of pyrrhotite at Iron Ridge during the early to mid 1900's. This area was mined for copper during the mid 1800's then iron in the 1880's. Lead mining started about 1750 with lead and zinc ores in quantity by 1838. Extensive economic geology section discusses barite, limonite, kyanite, magnetite, manganese oxides, copper minerals, pyrite, pyrrotite, rutile, ilmenite, staurolite, spesartite, zinc and lead minerals, soapstone, limestone, and building stone. Map includes locations of mines, prospects and old furnaces.
