This digital map database, which is compiled from previouslyunpublished and open-filed U.S. Geol. Survey reports (Wesling andHelley, 1989), represents the general distribution and identity ofQuaternary deposits in eight 7.5 minute quadrangles in the southernSan Francisco Bay region, California.
The Washington DC Area geologic map database (DCDB) provides geologic map information of areas to the NW, W, and SW of Washington, DC to various professionals and private citizens who have uses for geologic data. Digital, geographically referenced, geologic data is more versatile than traditional hard copy maps, and facilitates the examination of relationships between numerous aspects of the geology and other types of data such as: land-use data, vegetation characteristics, surface water flow and chemistry, and various types of remotely sensed images. The DCDB was created by combining Arc/Info coverages, designing a Microsoft (MS) Access database, and populating this database. Proposed improvements to the DCDB include...
This is a digital map database version of a previous U.S.Geological Survey Open-File Report, OF92-179. It contains 3Arc/Info formatted coverages, distributed in Arc Interchangeformat, a plottable map representation of the database at1:24,000 scale in Postscript and Adobe PDF formats, and theoriginal map explanation pamphlet in text, Postscript, andAdobe PDF formats.
New 1:24,000-scale geologic mapping in the Storm King Mountain7.5' quadrangle, in support of the USGS Western Colorado I-70Corridor Cooperative Geologic Mapping Project, provides new dataon the structure on the south margin of the White River upliftand the Grand Hogback and on the nature, history, anddistribution of surficial geologic units.Rocks ranging from Holocene to Proterozoic in age are shown onthe map. The Canyon Creek Conglomerate, a unit presently knownto only occur in this quadrangle, is interpreted to have beendeposited in a very steep sided local basin formed bydissolution of Pennsylvanian evaporite late in Tertiary time.At the top of the Late Cretaceous Williams Fork Formation is aunit of sandstone,...
This spreadsheet contains the results of open-bore auger samples collected by the U.S. Geological Survey in Maryland and Virginia for the Federal Highways Administration Turner-Fairbanks Highway Research Center. 19 sites were selected in 14 different locations across northern Virginia and southern Maryland by FBGC scientists to drill boreholes for the development of the TFHRC’s In-situ Scour Testing Device (ISTD) and to investigate the sedimentological properties of different layers of the near-surface soil column. Each worksheet in this excel workbook contains the detailed log information for one site, including its name, gps coordinates, surface elevation, borehole depth, information about the drilling rig used...

The State Geologic Map Compilation (SGMC) geodatabase of the conterminous United States (https://doi.org/10.5066/F7WH2N65) represents a seamless, spatial database of 48 State geologic maps that range from 1:50,000 to 1:1,000,000 scale. A national digital geologic map database is essential in interpreting other datasets that support numerous types of national-scale studies and assessments, such as those that provide geochemistry, remote sensing, or geophysical data. The SGMC is a compilation of the individual U.S. Geological Survey releases of the Preliminary Integrated Geologic Map Databases for the United States. The SGMC geodatabase also contains updated data for seven States and seven entirely new State geologic...

A GIS database of geologic units and structural features in Vermont, with lithology, age, data structure, and format written and arranged just like the other states.
This data set maps and describes the geology of the Devore 7.5' quadrangle, SanBernardino County, California. Created using Environmental Systems Research Institute'sARC/INFO software, the data base consists of the following items: (1) a map coveragecontaining geologic contacts and units, (2) attribute tables for geologic units(polygons), contacts (arcs), and site-specific data (points). In addition, the dataset includes the following graphic and text products: (1) A PostScript graphicplot-file containing the geologic map, topography, cultural data, a Correlation of MapUnits (CMU) diagram, a Description of Map Units (DMU), an index map, a regionalgeologic and structure map, and a key for point and line symbols;...
This Open-File report is a digital geologic map database. Thisdigital map database is compiled from previously published sourcescombined with some new mapping and modifications in nomenclature.The geologic map database delineates map units that are identifiedby general age and lithology following the stratigraphicnomenclature of the U. S. Geological Survey. For detaileddescriptions of the units, their stratigraphic relations, sourcesof geologic mapping, and data on exploratory wells consult Yerkes(1997), and Yerkes and Showalter (1990).
Mapped surficial units of the Springdale Quadrangle, Nye County,Nevada
This digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents the general distribution of bedrock and surficial deposits in the mapped area. Together with the accompanying text file (cdbegeo.txt or cdbegeo.ps), it provides current information on the geologic structure and stratigraphy of the area covered. The database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U.S. Geological Survey. The scale of the source maps limits the spatial resolution (scale) of the database to 1:24,000 or smaller.

The Palisade 1:24,000 quadrangle is in Mesa County in westernColorado. Because the map area is dominated by various surficialdeposits, the map depicts 22 different Quaternary units. Twoprominent river terraces are present in the quadrangle containinggravels deposited by the Colorado River. The map area containsmany mass movement deposits. Extensive landslide deposits arepresent along the eastern part of the quadrangle. These massivelandslides originate on the flanks of Grand Mesa, in the GreenRiver and Wasatch Formations, and flow west onto the Palisadequadrangle. In addition, large areas of the eastern and southernparts of the map are covered by extensive pediment surfaces.These pediment surfaces are underlain...
