This dataset contains high-resolution digital photographs of sediment cores collected from a boring drilled to bedrock near Nantucket Sound in East Falmouth, Cape Cod, Massachusetts. Following collection and transportation to a processing facility, the upper half of each core was scraped to form a flat surface along the length of the core. Digital photographs were taken of 8-inch (20-centimeter) sections of each core. The digital images were composited by using Adobe Illustrator to create a photographic log of each core. Abbreviations used in this metadata file: cm, centimeter; mm, millimeter; ft, foot; in., inch. This data release is associated with the following publications: Hull, R.B, Johnson, C.D., Stone,...
This database portrays the surface and shallow subsurface geology of the greater Charleston, S.C. region east of 80°30′ west and south of 33°15′ north. The region covers the entirety of Charleston County and portions of Berkeley, Colleton, Dorchester, and Georgetown Counties. Units locally exposed at the surface range in age from middle Eocene to Holocene, but most of the area is covered by Quaternary interglacial deposits. These are, from oldest to youngest, the Okefenokee, Waccamaw(?), Penholoway, Ladson, Ten Mile Hill, and Wando Formations and the Silver Bluff beds. Two cross sections (not included in the database), one running southeast from Harleyville to the coastline on James Island and the other running...
The U.S. Geological Survey (USGS), in cooperation with the Arkansas Geological Survey (AGS), has gathered available geophysical logs and related data from the USGS office archives in Arkansas and Tennessee as a basis for developing a hydrogeologic framework for the Southeast region of the United States. Similar efforts were undertaken by the Mississippi Embayment Regional Aquifer Study (MERAS) and the Regional Aquifer-System Analysis (RASA) Program. The logs compiled for these older efforts were difficult to access from the paper files; however, and partly because of this, older and newer logs were compiled into a single digital database for the current study.

This dataset includes a grid raster and contour line file representing the estimated altitude of the top of the Pennsylvanian-age units in western Sarpy County, Nebraska. This dataset was developed as part of a cooperative study between the PMRNRD and USGS which began in 2017. The goal of this study was to develop a hydrogeologic visualization model of western Sarpy County using GeoScene3D. In 2016, the Papillion-Missouri River Natural Resources District (PMRNRD) contracted airborne electromagnetic surveys (AEM) of the area to be completed to better understand the stratigraphy and hydrogeology of the western Sarpy County area. The PMRNRD determined that they wanted to incorporate the AEM data into a visualization...
Digital file containing a bedrock geology polygon coverage for British Columbia. Polygon coverage of geology compiled at 1:100,000 scale as part of the B.C. Ministry of Energy and Mines, BC Geological Survey Branch mineral potential project, 1994-1996. Original coding revised and rationalized in 2001-2002 by D.G. MacIntyre, updated and revised in 2002-2004 by N.W.D. Massey. Coverage generalized on lithostratigraphic map unit (MAPLABEL) designation. New mapping completed after 1996 is being added to this file on an ongoing basis. Bedrock Geology - This theme consists of a single layer of bedrock geology polygons. Polygons depict the nature of the bedrock geology based on a compilation of all geologic mapping done...
Lithostratigraphic and hydrogeologic observations for the unconfined aquifer of western Cape Cod are limited near coastal groundwater-discharge areas. In spring 2015, a 310-foot-deep boring was drilled and a well was installed to 100 feet below land surface to facilitate detailed study of aquifer characteristics along the southern coast of Cape Cod. Characteristics of interest included the depth and character of the freshwater/saltwater interface and bedrock surface, and vertical variations in grain size, bedding structure, and hydraulic conductivity. Sediment cores were collected from land surface to the bedrock surface at 305 feet below land surface. Bedrock cores were collected from 305 to 310 feet below land...

This data release contains digital data generated by the U.S. Geological Survey under cooperative agreements with Sonoma County Water Agency and the California State Water Resources Control Board to characterize the three-dimensional hydrogeology and water quality of the Russian River Watershed, located in the northern part of the California Coast Ranges section of the Pacific Border province. This dataset contains borehole lithologic and hydrologic data used to support development of the framework model . The borehole dataset is released as a series of .csv ascii files including (1) individual borehole location and construction information, (2) downhole lithologic interval data derived from well driller’s lithology...
The Cabin Branch and Cabin Creek (Cappy Avenue) outcrops are located along two small creeks in Prince George’s County, Maryland. The Cabin Branch outcrop contains exposures of silty sands of the Upper Cretaceous Severn Formation, and both outcrops contain Paleocene silty quartz and glauconitic sands of the Danian Brightseat Formation and highly fossiliferous glauconitic quartz sands of the Selandian Aquia Formation. Data from these two locations were generated in order to designate a Principal Reference Section for the Danian age Brightseat Formation. The Cabin Branch outcrop consists of disjunct exposures along an approximately 0.4-mile section of the creek. At the nearby Cabin Creek (Cappy Avenue) outcrop a more...
The database for the Preliminary Geologic Map of the Cherry Hill Quadrangle, Dinwiddie, Sussex, and Greensville Counties, Virginia geographically straddles the Coastal Plain and Piedmont Provinces along the Tidewater Fall Line. Rocks of the eastern Piedmont Roanoke Rapids terrane crop out in the western part of the quadrangle and consist of greenschist- to amphibolite-facies Neoproterozoic felsic to intermediate metavolcanic rocks, some of which contain flattened quartz phenocrysts and are locally isoclinally folded; greenstone that is locally primary layered; and intrusive metadiorite and metagabbro, much of which has been altered to amphibolite. Most of these rocks are strongly foliated and jointed. Greenschist-facies...
This dataset is a raster representing the estimated altitude of the top of the Pennsylvanian-age units in western Sarpy County. This dataset was developed as part of a cooperative study between the Papillion-Missouri River Natural Resources District (PMRNRD) and USGS which began in 2017. The goal of this study was to develop a hydrogeologic visualization model of western Sarpy County using GeoScene3D. In 2016, the PMRNRD arranged for airborne electromagnetic surveys (AEM) of the area to be completed to better understand the stratigraphy and hydrogeology of the western Sarpy County area. The PMRNRD determined that they wanted to incorporate the AEM data into a visualization tool (Geoscene3D) that would allow PMRNRD...

The Blue Ridge belt in northwestern North Carolina and northeastern Tennessee is composed chiefly of 1,000-million to 1,100-million-year-old metamorphic and plutonic rocks that have been thrust many miles northwestward across unmetamorphosed Cambrian(?) and Cambrian sedimentary rocks of the Unaka belt. The Blue Ridge thrust sheet is rooted on the southeast along the Brevard zone, a zone of strike-slip faulting along which metamorphic and plutonic rocks of the Inner Piedmont belt are juxtaposed with rocks of the Blue Ridge. Near the southeastern edge of the Blue Ridge belt, the Blue Ridge thrust sheet is breached by erosion, and the rocks beneath are exposed in the Grandfather Mountain window, which is 45 miles long...

This dataset contains geospatial data of a three-dimensional hydrogeologic framework model (3D HFM). The 3D HFM was constructed using methods from previously published reports. Sources of 3D HFM construction methods can be found in the metadata. The geospatial database contains a polygon feature class that is a 2-dimensional representation...
The Denver fossil algae database were gathered from the inception of Denver Region in 1953 by Richard Rezak. His specialty was algae, carbonate platforms, and off-shore modern reefs. He developed a very useful litho-stratigraphic tool while studying Proterozoic algae and stromatolites in Glacier National Park. This lead to his studies of modern analogs in the Caribbean and South Seas. This collection contains 1001 fossil localities. This collection was originally created and maintained by U.S. Geological Survey (USGS) and as of March 2020 has been transferred to the Smithsonian National Museum of Natural History.
