History:This collection of geologic, mine, and related maps was compiled and used by S. Warren Hobbs for his research on the Coeur d’alene Mining District, Idaho - Professional Paper 478 (1965).The Coeur d’Alene Study:General geology of the Coeur d’Alene district, one of the larger lead-, zinc-, and silver-producing areas of the world, is presented. The geology was remapped at a scale of 1:24,000 and compiled on five maps from west to east as follows: Smelterville, Kellogg, Wallace, Mullan, and Pottsville. Bedrock, primarily the Precambrian Belt Series which forms the host rock for the ore, is a thick conformable geosynclinal group of fine-grained clastics. Igneous rocks are principally two groups of small monzonitic...

This collection consists of rock samples associated with the research of USGS scientist Alfred Miesch. Miesch was an early contributor to USGS geochemistry research and many of these samples are associated with his research. In 1953 Dr. Miesch began a 33-year career with the Survey. His work in Grand Junction, CO involved research on the distribution of minor elements in association with uranium on the Colorado Plateau. He moved to Denver in 1959 where he continued his work on element distributions in rocks, soils, and plants, ultimately becoming Chief of the Branch of Geochemical Census, which he later renamed Branch of Regional Geochemistry. In this capacity he began a working relationship with scientists in the...
