Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

U-Pb Zircon Data for Igneous and Metaigneous Rocks of Interior and Southwest Alaska U-Pb Zircon Data for Igneous and Metaigneous Rocks of Interior and Southwest Alaska
This dataset contains U-Pb isotopic data and associated dates for sampled igneous, meta-igneous, and metamorphic rocks of interior and southwestern Alaska. Samples were collected during geologic mapping and mineral deposit research from 2019 to 2023. Mapping and research were funded by the Mineral Resources Program of the U.S. Geological Survey. Mineral separations were conducted at the...
Federal and Indian lands coal and other mineral production, value, and royalties by state, 1954-1980 and prior Federal and Indian lands coal and other mineral production, value, and royalties by state, 1954-1980 and prior
This data release includes a digitized version of the "Statistics by States, lands, products and years" section of the 1981 edition of the Federal and Indian lands coal, phosphate, potash, sodium, and other mineral production, royalty income, and related statistics publication. These data were published by the Conservation Division of the U.S. Geological Survey, which was tasked with the
High-resolution seismic imaging data from the West Napa Fault Zone acquired in 2015 at Hendry Winery, Napa, California High-resolution seismic imaging data from the West Napa Fault Zone acquired in 2015 at Hendry Winery, Napa, California
In February 2015, the U.S. Geological Survey conducted a high-resolution seismic survey across the West Napa Fault zone at Hendry Winery in Napa, California (Fig. 1). Geophones were deployed every 3 to 5 meters along a southwest-northeast trend to create an approximately 400-m-long linear array. Data were recorded by two Geometrics Stratavisor NZ-60TM seismographs. Both P-wave and S-wave...
Luminescence data for: Reconstructing the Quaternary depositional history using geologic mapping and a 3D model of the subsurface in the vicinity of Fort Morgan, Eastern Colorado Luminescence data for: Reconstructing the Quaternary depositional history using geologic mapping and a 3D model of the subsurface in the vicinity of Fort Morgan, Eastern Colorado
Centered on Fort Morgan, Colorado, this study is intended to build from previous work by adding a three-dimensional (3D) view of the subsurface to better understand the depositional history of Quaternary deposits. A 1:100,000 scale geologic map was made by combining previous geologic maps, regional soil maps, and recent field investigations. In addition to the geologic mapping, drill...
Datasets for Monitoring of a Passive-ISCO Experiment to Remediate a Chlorinated Ethene Plume, Naval Air Station Pensacola, Florida Datasets for Monitoring of a Passive-ISCO Experiment to Remediate a Chlorinated Ethene Plume, Naval Air Station Pensacola, Florida
Recalcitrant chlorinated ethenes in low-permeability units positioned adjacent to permeable aquifers are problematic because they are a prolonged source of contamination. Passive in situ chemical oxidation (P-ISCO) is a remediation method where the slow release of permanganate can oxidize chlorinated ethenes into less harmful chemicals. The success of P-ISCO is dependent on the...
Future U.S. Federal lease coal production and greenhouse gas emissions: Estimates 2024-51 - Data Future U.S. Federal lease coal production and greenhouse gas emissions: Estimates 2024-51 - Data
The dataset includes 2024-2051 estimates of projected United States Federal mineral rights lands coal production and the resulting greenhouse gas emissions (GHG) from mining, transporting, and combusting that fuel. The data cover six states and 30 coal mines. It is divided into four tables, one of coal production and three of GHG emissions. The coal production is presented with three...
