This release contains geospatial data digitized from the Map Showing Geology, Structure, and Oil and Gas Fields in the Sterling 1x2 Degree Quadrangle, Colorado, Nebraska, and Kansas (Scott, 1978) and was compiled as part of the National Geologic Synthesis project. The geospatial data depicts the geology of this quadrangle, which is dominated by Quaternary alluvial and aeolian deposits overlying Tertiary and Cretaceous sedimentary rock, including the Ogallala formation, the Fox Hills sandstone, and the Pierre shale. The included database includes spatial data depicting the locations of mapped geologic contacts and faults, polygons denoting the mapped surficial extent of geologic formations, and structural contours...

This shapefile contains cumulative fish habitat condition index (HCI) scores as well as specific disturbance indices for local and network catchments of Southeast Alaska. Catchments were created in support of Jared Ross's Master’s thesis. The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for assessing fluvial fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) broadly representative of conditions in the past 10 years, and (4) of sufficient spatial resolution that they could be used to make valid comparisons among local catchment units.

USGS Geochron is a database of geochronological and thermochronological dates and data. The data set contains published ages, dates, analytical information, sample metadata including location, and source citations. The following analytical techniques are represented in the data set: 40Ar/39Ar, K-Ar, U-Th-Pb, Sm-Nd, Rb-Sr, Lu-Hf, fission track, luminescence, U-series, (U-Th)/He, Re-Os, 10Be and 26Al cosmogenic, and radiocarbon. This data set incorporates data previously hosted in the National Geochronological Database (Sloan and others, 2003), as well as data from published journal articles and ScienceBase data releases. These data are primarily from the United States, but data from other parts of the world are also...

Landforms along the Pacific, Gulf of Mexico, and Atlantic coastlines for the conterminous United States are attributed with the relative vulnerability of horizontal erosion due to sea-level rise to characterize coastal zone stability. The position and extent of landforms are geospatially indexed as line-events where these coastal zone features are intersected by the linear-referenced 2013 - 2014 U.S. Geological Survey National Hydrography Dataset Coastline, which corresponds to the National Oceanic and Atmospheric Administration (NOAA) 2013 - 2014 mean high water level datum delineated in intertidal zones open to oceans, behind barrier coasts in bays, lagoons, and estuaries, and sometimes where tidal currents reach...

The Ouachita Mountains record the late Paleozoic Laurentia-Gondwana orogenic event along southern Paleo-North America during Pangea supercontinent formation. This data release contains a digital compilation of geomorphic-structural information from the Ouachita Mountains of southeastern Oklahoma and southwestern Arkansas as previously published by Arbenz (2008). The geodatabase, presented herein, contains feature classes that include contact, fault, fold, and cross section lines with map unit polygons characterized by predominantly siliciclastic material with primarily Paleozoic depositional ages. Spatial data are also disseminated as shapefiles, accompanied by applicable non-spatial tables detailing the data sources,...

This digital data release contains geospatial geologic data compiled for the Lamar 250k quadrangle, a region in eastern Colorado and western Kansas, which is predominantly covered by Quaternary deposits that overlay Cretaceous bedrock. Geologic data, compiled from published sources, include the location and characteristics of geologic contacts and faults, mapped geologic polygons, and ammonite fossils. The geologic database includes spatial feature classes that collectively contain the geologic information that are presented in the previously published map plate. The spatial data are accompanied by non-spatial tables that describe the sources of geologic information, a description of geologic map units, a glossary...
