Processes Controlling Groundwater Quality in Uranium In-Situ Recovery (ISR) Mining
The project's primary objective is to evaluate the reducing capacity of an aquifer down-gradient of a roll-front ore zone to assess the mobility of uranium and other associated elements (e.g. arsenic, selenium, molybdenum, and sulfur). Assessing the reducing capacity of the aquifer requires characterization of the mineralogy, geochemistry, and microbiology and their variation across the...
Mineville, Eastern Adirondacks – Geophysical and Geologic Studies
The USGS is using a set of advanced imaging and analysis tools to study the rocks within the eastern Adirondacks of upstate New York. The goal of these studies is to gain a better understanding of the geology and mineral resources in the area.
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...
Sources, Forms, Extractability of Metals in Non-Ore Deposit Sources
This project will explore potential recovery and environmental consequences of metals in mining and mineral processing wastes as a function of ore deposit geology, and in debris from demolished or burned buildings.
Trace Metal Mobility in the Yellow Pine Mining District, Idaho
The study objective is to conduct an integrated, interdisciplinary study on source areas, biogeochemical transformations, and physical and biological pathways for trace metal transport in a tributary of the Snake River watershed, focusing on the Sugar Creek watershed. The historical Cinnabar mercury mine site is at the headwaters of Cinnabar Creek, a tributary to Sugar Creek. This integrated...
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. 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 data sets and...
New Applications of Hyperspectral Imaging to Delineate Critical Minerals Concentrated in Regolith and Mine Waste Materials
Our project will develop new and innovative spectral methods and remote sensing tools for understanding how critical minerals are concentrated by weathering, regolith/soil formation, mining, runoff and ore processing. These tools will help us to use mineralogy derived from spectral measurements (lab, field, and remote sensing) to help delineate vectors towards recoverable resources and to...
USGS Abandoned Mine Lands Initiative
The U.S. Geological Survey (USGS) conducted an Abandoned Mine Lands (AML) Initiative during the fiscal years 1997 through 2001 to provide technical assistance in support of Federal Land Management Agency (FLMA) actions to remediate contamination associated with abandoned hard rock mining activities. This initiative was part of a larger strategy by the U.S....
