Two high-resolution aeromagnetic surveys in south-central Colorado compiled to assess the subsurface geologic framework of the San Luis basin for ground-water flow model construction, and to map concealed faults potentially related to geothermal resources

Flight-line aeromagnetic observations with gridded data derived from them.

Afghanistan has the potential to contain substantial metallic mineral resources. Although valuable mineral deposits have been identified, much of the country’s potential remains unknown. Geophysical surveys, particularly those conducted from airborne pl

Flight-line data and gravity grids with documentation.

Airborne magnetic survey data collected from this area to understand Precambrian rocks concealed under Paleozoic sedimentary rocks in northeast Iowa. Data are provided in GXF grid and CSV formats. Flight lines are provided in shapefile format.

Gravity data were collected from 2006 through 2015 to assist in mapping subsurface geology in this area. Includes principal facts for 567 new gravity stations that were acquired to fill in gaps in previously-available gravity data. Data are provided in CSV format.

Digital flight line data for a high-resolution magnetic survey with line spacing 150 meters and nominal terrain clearance 80 meters over most of the study area. Data are provided as Geosoft databases and grids. Data over two small areas (less than 1 sq km combined) were redacted because those areas include multiple tracts of Native American lands.

Airborne magnetic survey data collected from this area to better understand the lithology and structure of exposed and concealed Precambrian rocks in support of mineral resource investigations. Results are provided in Geosoft database, grid exchange format, GeoTiff, and CSV.

Survey to map concealed faults that may be related to geothermal resources, such as hot springs; data given are surface locations of faults interpreted from the survey.

Surveys originally carried out by Soviet geophysicists from 1972 through 1974 were digitized. Georeferencing was problematic as were some of the measured characteristics; we explain what we did and how we have understood these data.

Rock density and magnetic susceptibility measurements of samples drawn from this area. Data are provided in CSV format.

Gravity data collected 2016 through 2018 at 1080 locations to assist in mapping subsurface geology in northeastern Iowa. Data are provided in CSV format.

Digital flight-line aeromagnetic and aeroradiometric survey data over of the southeast Mojave Desert, parts of California and Nevada. Data files are provided in CSV as well as Geosoft binary database and grid exchange format (GXF).

Rock physical property measurements to help understand causative sources of gravity and magnetic survey anomalies in this area. Data are provided in CSV format.

Gravity data collected from 2016 through 2019 to assist in mapping surface and subsurface geology in this area. Data are provided in CSV and shapefile formats.

Aeromagnetic data collected during an airborne geophysical survey.

Digital data, image files, and text files describing data formats and survey procedures for an aeromagnetic survey covering the southwestern portion of Taos County west of the Town of Taos, New Mexico, conducted in October, 2006

Using geophysical and remote-sensing data, previously unrecognized targets of potential mineralization were identified; this report shows those targets along with the evidence for their potential.

This study delineated permissive areas for undiscovered porphyry copper deposits, compiled a database of known deposits and significant prospects, estimated undiscovered deposits within those areas and made probabilistic estimates of their metal content.

Compilation of airborne geophysical surveys (magnetic, radiometric, and electromagnetic) with links, for each survey to the data, metadata, and preview images. Includes a measure of quality indicating which surveys are likely most useful for investigations of subsurface mineral deposits. Data are provided in Esri file geodatabase, shapefile, and CSV formats.

Includes known resources and permissive tracts with estimates of the number of undiscovered resources likely to be present in the permissive tracts.

Geographic areas within the US where deposits of certain critical mineral resources might be found. With state agencies and other organizations, USGS intends to conduct studies that will help locate critical mineral resources within these areas.

Delineated permissive areas for undiscovered porphyry copper deposits, compiled a database of known deposits and significant prospects, estimated undiscovered deposits within those areas and made probabilistic estimates of their metal content.

New geologic map to reflect mapping of late Cretaceous to Tertiary clastic sedimentary rocks, park-wide mapping of surficial deposits, and a newly revised volcanic stratigraphy.

Gridded aeromagnetic anomaly data, along with aeromagnetic observations obtained during 2008.

Locations of focus areas to be used for planning and collection of geophysical, geological, and topographic (lidar) data pertaining to the study of rare earth element resources in the US.
