X-ray Fluorescence Geochemistry of Columbia River Basalt Group Rocks in the Western Columbia River Gorge X-ray Fluorescence Geochemistry of Columbia River Basalt Group Rocks in the Western Columbia River Gorge
This table contains geochemical data collected for whole-rock samples from the Columbia River Basalt Group in the western Columbia River Gorge in Oregon and Washington. Most samples were collected by Russell C. Evarts and Richard M. Conrey from 2002 to 2014. Samples were collected during traverses along roads, streams, ridgecrests, and other areas as part of ongoing geologic mapping...
Sr concentrations and 87Sr/86Sr data used to determine the Sr-chronostratigraphic age of sirenian fossils on Santa Rosa Island, Channel Islands National Park, California, USA Sr concentrations and 87Sr/86Sr data used to determine the Sr-chronostratigraphic age of sirenian fossils on Santa Rosa Island, Channel Islands National Park, California, USA
This data release includes a table of Sr concentrations and 87Sr/86Sr data used to evaluate primary seawater isotope compositions of marine invertebrate shell material used to estimate the Sr-chronostratigraphic age of sediments hosting early Miocene sirenian fossils on Santa Rosa Island of the Channel Island National Park, Ventura County, California
Digital database of the previously published Geologic Map of the Lamar Quadrangle, Colorado and Kansas Digital database of the previously published Geologic Map of the Lamar Quadrangle, Colorado and Kansas
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...
Digital Database of the Previously Published Geologic and Structure Contour Map of the La Junta Quadrangle, Colorado and Kansas Digital Database of the Previously Published Geologic and Structure Contour Map of the La Junta Quadrangle, Colorado and Kansas
This digital dataset release of the La Junta, Colorado and Kansas quadrangle is composed of previously published elevation contours, structure contours on the limits of the Morrison, Dakota, and Purgatorie Formations, and geologic formational data. The digitizing of this map is to provide a more accessible dataset to be available for public usage. The original dataset was part of an...
Digital database of the previously published geologic map of the Scottsbluff 1° x 2° quadrangle, Nebraska and Colorado Digital database of the previously published geologic map of the Scottsbluff 1° x 2° quadrangle, Nebraska and Colorado
This data release contains a digital compilation of geologic data from the Scottsbluff 1° x 2° quadrangle of western Nebraska and northeastern Colorado, a region predominantly characterized by Quaternary and Tertiary sedimentary and extrusive igneous rocks. This geodatabase, digitized from published resources, includes the position of volcanic ash-bed localities, structural data of...
Digital database of the previously published Geologic maps and cross sections showing configurations of bedrock surfaces, Broken Bow 1 degree x 2 degree quadrangle, east-central Nebraska Digital database of the previously published Geologic maps and cross sections showing configurations of bedrock surfaces, Broken Bow 1 degree x 2 degree quadrangle, east-central Nebraska
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...
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.
Demographic and potential biological removal models identify raptor species sensitive to current and future wind energy Demographic and potential biological removal models identify raptor species sensitive to current and future wind energy
A central challenge in applied ecology is understanding the effect of anthropogenic fatalities on wildlife populations and predicting which populations may be particularly vulnerable and in greatest need of management attention. We used 3 approaches to investigate potential effects of fatalities from collisions with wind turbines on 14 raptor species for both current (106 GW) and...
Wildland-urban interface maps for the conterminous U.S. based on 125 million building locations Wildland-urban interface maps for the conterminous U.S. based on 125 million building locations
The wildland-urban interface (WUI) is the area where urban development occurs in close proximity to wildland vegetation. WUI maps for the conterminous U.S. were generated using building point locations, offering higher spatial resolution compared to previously developed WUI maps based on U.S. Census Bureau housing density data (Radeloff et al., 2017). Building point locations were...
