New Mineral Deposit Models for Gold, Phosphate Rare Earth Elements, and Placer Rare Earth Element-Titanium Resources
USGS Mineral Deposit Models are "an organized arrangement of information describing the essential characteristics or properties of a class of mineral deposits. Models themselves can be classified according to their essential attributes (for example: descriptive, grade-tonnage models, genetic, geoenvironmental, geophysical, probability of occurrence, and quantitative process models)." (Stoeser and Heran, 2000). They are a tool for assessing areas for undiscovered mineral deposits.
This project focused on updating mineral deposit models for future assessment work within the U.S. The updated models included 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 designed for assessment use and include components on geoenvironmental impacts, human health, and critical elements. Other activities included investigating modern techniques in the applications of geochemistry and geophysics for all gold models.
