Non-Traditional Stable Isotopes

Understanding the genesis of ore deposits and their behavior in the environment is a subject of great importance to the Nation. A relatively new tool to aid in these efforts to investigate the origin and environmental effects of ore deposits is the use of "heavy" metal stable isotopes. Our research objectives are to utilize various isotopic systems to advance our understanding of ore genesis and...

Salmon River Mountains Legacy Mining Studies

The objective of this study is to characterize the regional impact of legacy mining in the context of framework geology for the Salmon Mountains in central Idaho. This objective is addressed through three interrelated tasks: 1) framework geology, 2) watershed biogeochemical processes, and 3) characterization of trace metals in colloids (fine particles suspended in water).

A Shallow to Deep View Inside the Hydrothermally Altered and Mineralized Silverton Caldera Complex: New Geologic Insights Gained From Modern Geophysical Interpretations

The Silverton caldera complex in southwest Colorado hosts base and precious metals that have been mined since the late 1800s. Extensive mine workings, excellent bedrock exposures, and deeply incised drainages make this area a natural laboratory ideally suited for furthering our understanding of the mineral systems in a volcanic environment. In addition, state-of-the-art geophysical data processing...

Multi-scale Screening Techniques for Legacy Mine Land (LML) Sites Using Data Mining and Site-specific Studies in the Western U.S.

The main goal of this project is to provide a science-based approach for screening legacy mine land (LML) sites for remediation and identifying watersheds where relatively low-cost restoration efforts may yield substantial improvements to stream water quality. We are combing analysis of multiple existing regional data coverages with focused field studies to develop a protocol that land managers...

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...
