Update of North American Airborne Radiometric Survey Data Using Advanced Statistical Techniques and Parallel Computing
The purpose of this project is to update the current gridded products created from the North American airborne gamma ray spectrometry data using new statistical techniques to analyze spatial data and to create higher quality national airborne radiometric grids.
Critical Mineral Recovery Potential from Tailings and Other Mine Waste Streams
The primary objectives of this one-year scoping project are to determine the feasibility of extracting byproduct mineral commodities, such as critical minerals, from mine tailings. We plan to analyze the existing data and reports from an active mine site on the composition of their mill tailings pile, and collect preliminary reconnaissance samples to identify appropriate analytical techniques that...
Research Mineralogy - X-ray Diffraction Lab
The primary goal of this project is to ensure the availability of state-of-the-art mineralogical analyses and, when needed, development of new analytical methods that can be applied to topical studies in Energy and Minerals Mission Area, as well as the other mission areas. The project includes mineralogy by X-ray diffraction (XRD), qualitative and semi-quantitative x-ray fluorescence spectroscopy...
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.
Mineral Resource Assessment Training
The USGS Mineral Resources Program conducts mineral resource assessments and is training USGS scientists in how to conduct these assessments for future work. As a practical exercise, the scientists will conduct an assessment for tungsten in the U.S.
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...
Unconventional Stratabound Critical Mineral Deposits of the Midcontinent: Linkages Between Mineralization in Marine Epicontinental Sedimentary Basin Systems
This project will evaluate and characterize the critical mineral potential of midcontinent stratabound "Bathtub Rim" deposits for rare earth elements, cobalt, lithium, and associated critical mineral prospectivity and to develop and test new ore genesis models.
Volcanic-related Beryllium Deposits of the US: Geologic Setting, Genesis, and the Potential for Post-Extraction Recovery of By-Product Critical Minerals
Project objectives are: 1) to fully establish a comprehensive and robust geologic and geochemical framework for the occurrence of volcanic-related beryllium (Be) deposits; 2) further our understanding of the fundamental ore processes that lead to formation of volcanogenic beryllium (Be)-boron (B)-lithium (Li)-phosphorus (P) group deposits, by investigating processes favorable for enhanced...
Geochemical Signatures and Environmental Impacts of Ore and Trace Mineralization in the Southern Midcontinent
The overall project objective is a comprehensive analysis of the natural and anthropogenic consequences of extensive ore and trace mineralization in the southern midcontinent of the U.S. with a focus on Missouri. This will be conducted at two scales: 1) landscape and 2) process-level. 1) Landscape scale using geospatial and machine learning techniques to combine multiple geochemical and geologic...
Critical Mineral Resources in Heavy Mineral Sands of the U.S. Atlantic Coastal Plain
In many parts of the southeastern U.S., dark-colored sands can be seen at beaches or beneath soil. These sands contain titanium, zirconium, and rare earth elements, which are considered critical mineral resources. Such sands are present in areas from the coast to a hundred miles or more inland beneath soil within the Atlantic Coastal Plain Province. In some locales they are concentrated enough to...
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...
Antimony In and Around the Yellow Pine Deposit, Central Idaho
Project objectives are to document the origin of the Yellow Pine gold-antimony deposit and, by extension, the origin of this deposit type. Our goal is to understand the structural, tectonic, and magmatic setting of the deposit, the character of the ore-transporting fluids, the conditions of ore deposition, and the regional stratigraphic framework and geochemical ore controls of metasedimentary...
