Petrogenesis and REE Metallogenesis of 1.4 Ga Magmatism in the Conterminous U.S.
This project evaluated the petrology and metallogeny of rare earth element-mineralized 1.4 Ga intrusive systems at Mountain Pass and in the St. Francois Mountains relative to those of other, apparently, unmineralized 1.4 Ga intrusive systems in the conterminous U.S.
Basement Tectonic Framework of the U.S.: Role of Cratonization of Juvenile Crust and Structural Modification in Forming Metallogenic Provinces
Project objectives were to publish a map of the nation's geologic basement. The map portrayed these pieces (domains) from the most ancient to recent, by the events that influenced their composition, starting with their origin.
Headwaters Province - Idaho and Montana: Earth Science Studies in Support of Public Policy Development and Land Stewardship
The Headwaters Province project provided geoscience data and interpretations to the Federal Land Management Agencies (FLMA) that were basic to sound policy and land-stewardship practices.
