Geospatial Analysis and Mapping

The project seeks to better understand the mineral systems of the Boulder batholith and surrounding region in Montana using new airborne geophysical data in conjunction with geologic mapping.

Our objective is to develop a national-scale, geospatial database that is the authoritative source of the most important mines, mineral deposits, and mineral districts of the United States.

The USGS, in combination with Geoscience Australia and the Geological Survey of Canada, formed the Critical Minerals Mapping Initiative (CMMI) in 2019 to combine expertise and collaboratively conduct research on critical mineral resources.

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).

The goal of the Northern Rocky Mountains Transect (NRMT) project is to produce updated geologic maps of an important and understudied region of Idaho and western Montana that covers a wide array of distinct geologic terrains.

We provide support for geospatial analyses, mobile field data collection, management of geospatial collections including documentation, and distribution of all dataset types (geophysical, geochemistry, remote sensing (hyperspectral), etc.). GIS and data management support are provided including hyperspectral and geophysical studies that improve capabilities and applications for investigating...

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...

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...

We are researching the subsurface groundwater flow systems in Yellowstone and the relation of these systems to understanding the regional movement of water in a volcanic center. New geophysical data will be integrated with existing data sets from hyperspectral data from Yellowstone's thermal areas and thermal water geochemistry to help define regionally extensive mineral assemblages, the evolution...

The project focuses on the development of novel geophysical techniques that improve our ability to understand Earth's subsurface, with broad relevance to the Mineral Resources Program and the USGS Science Strategy. Our goal is to develop and maintain state-of-the art geophysical capabilities that support the diverse science needs of USGS projects that aim to meet the challenges of the 21st century...

We support the geospatial component of Mineral Resources Program research and provide public access to research results and geospatial information. We facilitate all aspects of the data life cycle, including the publication and archiving of geospatial information and products. We also develop and steward national-scale data layers considered foundational to the Mineral Resources Program as well as...

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.
