Project Objectives

Mineral deposit models are essential for assessing areas for undiscovered mineral resources. There is a need for updated mineral deposit models for gold deposits, phosphate-rare earth element deposits, and placer titanium-rare earth element deposits. Project objectives are to develop eight mineral deposit models for future assessment work within the U.S. These will include six gold deposit types (epithermal, orogenic, Carlin-like, alkaline-related, iron oxide copper gold, and Precambrian paleoplacer), sedimentary phosphorus (± rare earth elements) deposits, and titanium-rare earth element placer deposits. These mineral deposit models are design for assessment use and will include components on geoenvironmental impacts, human health, and critical elements. Other activities include investigating modern techniques in the applications of geochemistry and geophysics for all gold models.
