This digital data release contains spatial datasets of bedrock geology, volcanic ash bed locations, test hole locations, bedrock outcrops, and structure contours of the top of bedrock and the base of the Ogallala Group from a previously published map (Souders, 2000). The GeologicMap feature dataset contains separate feature classes for the Ogallala Group map unit (ContactsAndFaults and
Digital database of the previously published Geologic map of the Limon quadrangle, Colorado and Kansas Digital database of the previously published Geologic map of the Limon quadrangle, Colorado and Kansas
This digital data release contains geospatial geologic and paleontological data of the 1° x2 °, 1:250,000 Limon quadrangle covering eastern Colorado and western Kansas. The dataset is a digital reproduction of previously published U.S. Geological Survey field mapping which illustrates the spatial configuration of primarily Quaternary surficial units overlying upper Miocene, Oligocene...
Aeromagnetic Data of Portola, California, and Surrounding Areas Aeromagnetic Data of Portola, California, and Surrounding Areas
This data release provides access to an aeromagnetic survey over a part of northern California, an area that includes the cities of Portola, California, and Reno, Nevada. The survey extends across the northern part of the Sierra Nevada from Honey Lake in the north to Lake Tahoe in the south and over parts of the Sierra Nevada foothills. These data were acquired between March 3 and May 3...
Data Release for Luminescence: Geologic map of Scoggins Dam, Henry Hagg Lake, and the Scoggins Valley area, Washington County, Oregon Data Release for Luminescence: Geologic map of Scoggins Dam, Henry Hagg Lake, and the Scoggins Valley area, Washington County, Oregon
The Bureau of Reclamation's Scoggins Dam lies within the Gales Creek fault zone southwest of Hillsboro, Oregon. Recent geologic mapping shows the dam to overlie a potentially active strand of the fault. This report describes the geology of the dam in detail and confirms that the dam overlies a strand of the Gales Creek fault. The report documents small faults in the reservoir and off the...
Data release for geochronology and geochemistry of volcanic rocks in the Southern Rocky Mountains and Taos Plateau volcanic fields and other Oligocene to Pleistocene volcanic rocks within the southern San Luis Basin and San Juan Mountains, southern Colora Data release for geochronology and geochemistry of volcanic rocks in the Southern Rocky Mountains and Taos Plateau volcanic fields and other Oligocene to Pleistocene volcanic rocks within the southern San Luis Basin and San Juan Mountains, southern Colora
The dataset includes whole-rock geochemistry and 40Ar-39Ar geochronology for Pleistocene to Oligocene volcanic and intrusive rocks. These data support figures and tables in days 2 and 3 of the Field-trip guide to continental arc to rift volcanism of the southern Rocky Mountains-Southern Rocky Mountain, Taos Plateau, and Jemez Mountains volcanic fields of southern Colorado and northern...
Detrital zircon geochronology and geochemistry data from the seafloor of the Bering Sea and adjacent river systems Detrital zircon geochronology and geochemistry data from the seafloor of the Bering Sea and adjacent river systems
This dataset archives geochronology and geochemistry measurements from detrital zircons collected from samples taken from the Bering Sea and its major feeder rivers.
Literature compilation of paleocurrent data from the Late Paleozoic Ouachita orogen, Oklahoma-Arkansas, U.S.A. Literature compilation of paleocurrent data from the Late Paleozoic Ouachita orogen, Oklahoma-Arkansas, U.S.A.
This digital geospatial compilation gathered paleoflow indicators from current-formed sedimentary structures throughout the Paleozoic Ozark uplift, Arkoma foreland basin, and Ouachita fold-thrust-belt of eastern Oklahoma and western Arkansas from existing publications. This dataset consists of unidirectional and bidirectional paleocurrents observed from a variety of bedform types...
Data Release - Digital subsurface data from previously published contoured maps of the tops of the Mowry Shale, Morrison Formation, and Minnelusa Formation, Powder River basin, Wyoming and Montana Data Release - Digital subsurface data from previously published contoured maps of the tops of the Mowry Shale, Morrison Formation, and Minnelusa Formation, Powder River basin, Wyoming and Montana
This digital data release contains previously published contours on the tops of the Mowry Shale, Morrison Formation, and Minnelusa Formation. The maps are from a series of U.S. Geological Survey Miscellaneous Field Studies (MF) showing computer-generated structure contours, isopachs, and cross sections of selected formations in the Powder River basin, Wyoming and Montana (Crysdale 1990...
Digital subsurface data from previously published maps of the base and thickness of post-Eocene continental deposits in the Sacramento Valley, California Digital subsurface data from previously published maps of the base and thickness of post-Eocene continental deposits in the Sacramento Valley, California
Post-Eocene (predominantly Pliocene) continental sedimentary rocks of the Sacramento Valley, CA are up to 1,200 m thick beneath the valley. These rocks contain most of the fresh ground water in the valley, forming a key component of the total water budget for the valley. A 1974 study by the U.S. Geological Survey was an early attempt to develop detailed knowledge of the subsurface...
A geodatabase of Surficial Geology of the Allentown 30x60-Minute Quadrangle in Pennsylvania digitized from the original map of Braun, 1996 A geodatabase of Surficial Geology of the Allentown 30x60-Minute Quadrangle in Pennsylvania digitized from the original map of Braun, 1996
This Scientific Data Release is a spatial geodatabase representation of Braun, D. D., 1996, Surficial geology of the Allentown 30x60-minute quadrangle: Pennsylvania Geological Survey, 4th ser., Open-File Report 96-48, 17 p., 1 map, scale 1:100,000. These geospatial data depict surficial geologic materials in the Pennsylvania portion of the Allentown 30 x 60-minute quadrangle in eastern
Digital subsurface data from previously published contour map of the top of the Wilcox Group, northern Gulf of Mexico coastal region Digital subsurface data from previously published contour map of the top of the Wilcox Group, northern Gulf of Mexico coastal region
The lower Paleogene Wilcox Group crops out around the northern edge of the Gulf of Mexico Basin and is a major coal-bearing unit and a primary oil and gas producer in the lower Paleogene section of the Gulf Coast region. The outcrop distribution of the Wilcox Group and other coal-bearing strata of the Gulf Coast region was compiled as part of a U.S. Geological Survey National Coal...
Fault data collected between 1996 and 2019 from the Buffalo River watershed area, northern Arkansas Fault data collected between 1996 and 2019 from the Buffalo River watershed area, northern Arkansas
Information on the locations and characteristics of faults were collected while conducting fieldwork between 1996 and 2019 in support of geologic mapping in the Buffalo River watershed area of northern Arkansas. A total of 1274 entries on faults were recorded at 452 sites. The observations associated with faults include seven categories of increasing completeness of information.
