Geospatial (GIS) Data

The Alaska Resource Data File (ARDF) site provides descriptions of mines, prospects, and mineral occurrences for individual U.S. Geological Survey 1:250,000-scale quadrangles in Alaska.

The objective of this project is to provide targeted research results to benefit cooperators managing legacy mine land sites in the western U.S. by addressing three persistent scientific challenges: (1) determining the contribution of mining-related metal sources to water quality degradation when substantial natural background metal sources are also present; (2) adequately characterizing key...

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.

Alaska is dominated by a history of tectonic events that foster mobilization and concentration of a wide variety of mineral commodities that are critical to the US economy and are vital to national defense, renewable-energy, and emerging electronics technologies.

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...

This project makes the digital spatial data produced by the Mineral Resources Program available via a web portal so that users can easily access spatial data for solving scientific and technical problems: the Mineral Resources Online Spatial Data site.

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.
