USGS mineral deposit models

This CD-ROM publication is a compilation of 29 previously published mineral deposit model and related reports of the USGS. It in part reflects a history of mineral deposit model development within the USGS. Model types presented include descriptive, grade-tonnage, geoenvironmental, and geophysical. These models generally compile the geologic, geochemical, and geophysical characteristics of various types of metallic and nonmetallic mineral deposits. The models list attributes intended as guides for resource and geoenvironmental studies and for mineral exploration. They are presented using the lithologic-tectonic environmental mineral deposit classification scheme originally developed by Cox and Singer (1986).
