Ultramafic-Hosted Talc-Magnesite Deposits
This presentation on the geology of ultramafic-hosted talc-magnesite deposits was given at the 42nd Forum on the Geology of Industrial Minerals, May 7-13, 2006, in Asheville, North Carolina (USA). Talc is a soft inert industrial mineral commodity commonly used as a component or filler in ceramic, paint, paper, plastic, roofing, and electrical...

Preliminary integrated geologic map databases for the United States : Central states : Montana, Wyoming, Colorado, New Mexico, Kansas, Oklahoma, Texas, Missouri, Arkansas, and Louisiana
The growth in the use of Geographic Information Systems (GIS) has highlighted the need for regional and national digital geologic maps attributed with age and lithology information. Such maps can be conveniently used to generate derivative maps for purposes including mineral-resource assessment, metallogenic studies, tectonic studies, and...

Van Gosen, Bradley S. A USGS Study of Talc Deposits and Associated Amphibole Asbestos Within Mined Deposits of the Southern Death Valley Region, California
Van Gosen, Bradley S.; Lowers, Heather; Sutley, Stephen J.
Using the geologic setting of talc deposits as an indicator of amphibole asbestos content
This study examined commercial talc deposits in the U.S. and their amphibole-asbestos content. The study found that the talc-forming environment directly influenced the amphibole and amphibole-asbestos content of the talc deposit. Large talc districts in the U.S. have mined hydrothermal talcs that replaced dolostone. Hydrothermal talcs, created by...

Hammarstrom, Jane M; Wilson, Anna B.; Van Gosen, Bradley S. Reconnaissance study of the geology of U.S. vermiculite deposits: Are asbestos minerals common constituents?
Unusually high incidences of asbestos-related mortality and respiratory disease in the small town of Libby, Montana, have been linked to amphibole mineral fibers intergrown with the vermiculite deposits mined and milled near the town from 1923 to 1990. A study conducted by the U.S. Agency for Toxic Substances and Disease Registry concluded that...

The Thompson Creek mine is an inactive and abandoned tungsten mine located along Thompson Creek about 10.5 miles (17 km) northwest of Clayton, Idaho (see location map in file LOCATION.PDF). The mine consisted initially of open pit mining of outcrops and later of underground workings accessed by a single adit. The mine was worked through 1955 and...
