| Abstract

"This book provides the results of a multifaceted, multidisciplinary, multi-agency program headed by the US Geological Survey to study to 350,000 square kilometer Western US Phosphate Field. The program addresses mainly the Permian Phosphoria Formation (the world's largest phosphate deposit), including the nature of the Phosphoria sea, resource-reserve estimates, mineralogical-geochemical-tectonic evolution of the deposit, and present-day contaminant issues associated with release of selenium from waste-rock dumps produced during mining. This latter issue involves surface and ground water, soil, biota, and rock studies. The Phosphoria Formation occurs over extensive regions of Montana, Idaho, Wyoming, and Utah, where there are five operating mines that collectively produce about 15% of the US production of phosphate. Vanadium was also mined up until 1999 from the Phosphoria and the deposit was considered at one time as a potential source for uranium. The Phosphoria Formation is a world-class deposit and knowledge grained from these studies can be applied to many other deposits world-wide. This book will be of interest to environmental geologists and biologists, economic geologists, mineralogists, sedimentologists, oceanographers, geochemists, among others from industry, Federal-State-local governmental agencies, and academia"--Back cover
