Western Alaska Range Metallogeny and Tectonics
There are many different types of mineral deposits present in the Western Alaska Range: plutonic gold, porphyry copper-gold (Pebble prospect), epithermal gold, tin-silver skarns, sedimentary barite, mafic hosted nickle-platinum-group elements, uranium-thorium rare earth elements, and even a diamond prospect.
ASTRA: ASTeroid Resource Assessment
The study was conducted to determine if the USGS process for conducting mineral resource assessments on Earth can be applied to asteroids
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.
Sagebrush Mineral Resource Assessment
The USGS Mineral Resources Program completed a comprehensive assessment and inventory of potential mineral resources covering approximately10 million acres of federal and adjacent lands in Oregon, Idaho, Nevada, Utah, Wyoming and Montana.
Fluids in Rare Earth Element (REE) Ore Genesis
The project objective is to better understand the role fluids play in the formation of ore-grade rare earth element enrichment. In many rare earth element deposits, enrichment of rare earth elements is largely controlled by their transport in fluids (orthomagmatic, hydrothermal, groundwater). The project focuses on carbonatite-related deposits because these deposits are the world's primary source...
Application of the National-Scale Soil Geochemical and Mineralogical Data for the Conterminous U.S.
Project goals were to produce interpretive products based on the existing national-scale geochemical and mineralogical data and maps for soils of the conterminous U.S.
Nonmetallic Industrial Mineral Resources of the U.S.
In 2012, this project initiated a multi-year effort to characterize domestic nonmetallic industrial mineral resources that are important for national infrastructure, agriculture, and energy development. Activities included (1) a national-scale compilation of production data, providing a snapshot of the nonmetallic industrial mineral deposits that were of significance through the 20th century and...
Denver Microbeam Laboratory
TThe USGS Denver Microbeam Laboratory provides critical analytical and characterization support for a wide variety of internal USGS projects and external collaborators. In addition, the lab continually works to develop new methods or improve existing methods to analyze a variety of sample matrices.
Critical Metals in Black Shales
Project objectives were to improve the understanding of critical mineral enrichment in black shales and improve accuracy of resource assessments.
Bokan Mountain and Dora Bay Rare Earth Element Deposits, Prince of Wales Island, Alexander Terrane, Southeast Alaska
We sought to characterize the Dotson Zone heavy-rare earth element (HREE) enriched deposit at Bokan Mountain, Alaska, and conduct a parallel characterization and comparison of a less well-mineralized HREE analogue at Dora Bay, Alaska.
Multidisciplinary Studies to Image and Characterize the Mineral Resource Potential of the Midcontinent Rift, USA
This multidisciplinary study seeks to image and characterize the mineral resource potential of the Midcontinent Rift System. Combining various geophysical methods with detailed mapping and geochemical analyses will help to define the geographic extent of the Rift and clarify its geologic makeup and configuration.
Geophysical and Geochemical Approaches to Evaluating Rare Earth Element (REE) Potential in the Southeastern U.S.
Rare-earth elements (REE) are an essential component of numerous advanced technology applications including high efficiency batteries, emerging energy technologies, and key defense systems. The goal of this study was to assist in the evaluation of the distribution of rare earth element deposits in the southeastern U.S., with a focus on sediment-hosted resources.
