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.
Geoenvironmental Model Refinement and Advancement
The overall objective of our project is to take the abundant geoenvironmental model research that the Mineral Resources Program has supported, and use it to refine the geoenvironmental model concept to make it more useable for our current stakeholders.
Geochemical Signatures of Covered Mineral Deposits in the Northern Midcontinent
We are evaluating the potential of geochemical prospecting techniques that have shown promise in other covered terranes for mineral exploration in the northern midcontinent of the U.S. Novel components will be added to these methods with the objective of method advancement and improving our understanding of processes controlling the transmission of unique geochemical signatures from buried mineral...
Emerging Geoenvironmental Issues Related to Proposed Mining in the Lake Superior Region
We are studying environmental issues related to mining, and potential mining, in the Great Lakes region, continuing the study of characterizing baseline geochemistry of several watersheds in Minnesota and Michigan, examining the potential for aquatic toxicity from metals, and examining the acid-neutralizing and acid-generating potentials of mine waste, and the environmental, and possible human...
Beryllium: Economic Geology, Material Flow, and Global Importance of a Key Critical Mineral
Beryllium (Be) is a critical metal mineral commodity with unique chemical properties, making it indispensable to the computer, telecommunication, aerospace, medical, defense, and nuclear industries. We are studying known deposits of beryllium to determine where undiscovered beryllium resources might be found, analyzing how and where beryllium becomes concentrated in Earth’s crust, gathering a...
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...
Data Information Management and Technology - Eastern Minerals
The Data Information Management and Technology project provides geographic information systems (GIS) management and technical support to projects of the Geology, Energy & Minerals (GEM) Science Center. The project facilitates geospatial data development, compiling, documentation, visualization, analyses, modeling, and product requirements using the GIS framework. The project provides technical...
Petrology, Tectonic Setting, and Potential for Concentration of Rare Earth Elements (REE) and High Field Strength Elements (HFSE) in the High-K Darby and Kachauik Plutons, Seward Peninsula, Alaska
One of the geologic environments that host rare earth and other critical and strategic element deposits are alkaline intrusive rocks.
Backgrounds and Baselines
This project developed a geochemical information base through studies ranging in scale from site-specific to regional and national.
