Handbook of exploration and environmental geochemistry ; v. 8
Content:
Geological, geoenvironmental, and resource studies were completed to study a world-class phosphate ore in the Western US Phosphate Field. This integrated, multi-agency, multidisciplinary research emphasized: (1) Geological and geochemical baseline characterization of the deposit and associated rocks, (2) Delineation, assessment, and spatial analysis of phosphate resources and lands disturbed by mining, (3) Contaminant residence, reaction pathways, and environmental fate associated with the occurrence, development, and use of phosphate rock, and (4) Depositional origin and evolution of the Ph
