Geothermal Resource Investigations Project
Geothermal energy is a significant source of renewable electric power in the western United States and, with advances in exploration and development technologies, a potential source of a large fraction of baseload electric power for the entire country. This project focuses on advancing geothermal research through a better understanding of geothermal resources and the impacts of geothermal...
Geophysical Studies on the Architecture of Large Igneous Systems Hosting Magmatic Ore Deposits
Platinum group elements, also known as PGEs, are a group of elements that have specific properties which make them useful for various applications in industry. One geologic setting that contains large concentrations of platinum group elements is layered mafic intrusions. This project will use new and preexisting geophysical datasets to characterize the internal structure of layered intrusions...
Lithium from Source to Sink: Genesis and Evolution of Li Brines and Clays
The purpose of this project is to trace the lithium (Li) geochemical cycle in the Great Basin, with an emphasis on the pathways that lead to the development of lithium clay and brine resources.
Concealed Rare Earth Element (REE) Terranes in the Southern Basin and Range Geologic Province
We are working to develop an understanding of the types, sizes, and spatial distribution of rare-earth element (REE) related deposits in the Southern Basin and Range geologic province to help ensure the availability of REEs to industry in the United States. Geologic, geophysical, and geochemical data acquired will be used to develop permissive tracts for REE related deposits and to define areas of...
Systems Approach to Critical Minerals Inventory, Research, and Assessment
This project supports the Earth Mapping Resources Initiative (EarthMRI) by developing a mineral systems approach for defining focus areas. This project is investigating domestic sources of critical minerals in three sequential stages: inventory, research, and assessment. 1) Inventory the abundance of critical minerals in ore, minerals, and processed materials from major deposits in each system...
USGS Response to Possible Metals Contamination from Legacy Mines in the Patagonia Mountains Region and Adjacent Areas, Southeast Arizona and a Template for Future Mineral Environmental Emergency Response
USGS is conducting sampling, monitoring, and modeling in the Patagonia Mountains and nearby regions in Arizona to identify contaminant risk potential of legacy and proposed mine sites and to develop classification criteria for predicting vulnerabilities and targeted sources and sinks of metal contaminants.
Platinum-Group Elements in Layered Intrusions Associated with the Midcontinent Rift
Platinum-group elements (PGE) are critical commodities. They are essential for the U.S. economy; however the U.S. imports about 90 percent of the platinum-group elements that we need to use. The project objective is to assess the Duluth Complex and related mafic-ultramafic intrusions in the 1.1 Ga Midcontinent Rift System in the Lake Superior region. Our current activities focus on a Keweenawan...
Magmas to Metals: Melt Inclusion Insights into the Formation of Critical Element-Bearing Ore Deposits
This project applies innovative melt inclusion and mineralogical techniques to characterize several distinctive magma types occurring together with prodigious, critical rare earth elements (REE) and gold-(antimony-tellurium) ore deposits within the U.S. We will characterize the pre-eruptive/pre-emplacement magmatic conditions in several districts. The goal is to determine the role of magmatism in...
Mineral Resource Assessment of U.S. Territories of the Caribbean Basin Archipelago including Puerto Rico, U.S. Virgin Islands and Adjacent Areas
Project objectives are to develop a modern probabilistic quantitative mineral resource assessment of Puerto Rico, U.S. Virgin Islands and adjacent geologically similar areas that examines the potential for minerals-based economic development and trade within the region.
Development of Assessment Techniques and Analysis Project II (DATAP II)
The Development of Assessment Techniques and Analysis Project (DATAPII) objective is to modernize the application and development of USGS mineral resource and integrated multiresource assessment methodologies and capacity that are applicable at a variety of spatial and temporal scales, and national and international in scope.
Databases and Information Analysis
Our objectives are to: 1) collect and assimilate digital geospatial data in a standardized format for minerals-related research and assessments, 2) develop and improve analytical procedures for using geospatial data in minerals products, 3) provide support for timely, quality, and reproducible mineral assessments, 4) provide easy access to the data, and 5) report results of our work in a digital...
Rare Earth Element Deposits in the Southeast Mojave Desert
In an effort to better understand domestic resource potential, the USGS is investigating the genetic relationship between rare earth element deposits at Mountain Pass, California and Music Valley (Pinto Mountains, California) and extend these studies across a 130-km long belt of alkaline Proterozoic rocks in the southeast Mojave Desert. Such a combined study would significantly improve our...
