Gravity and physical property data, basin depth of the Hayfork graben, and horizontal gradient maxima of the southern Klamath Mountains, California Gravity and physical property data, basin depth of the Hayfork graben, and horizontal gradient maxima of the southern Klamath Mountains, California
This data release contains principal facts of gravity measurements collected by the U.S. Geological Survey in 2013-2022, a compilation of existing and new density and magnetic susceptibility data, horizontal gradient maxima derived from gravity and magnetic potential fields, and depth of Cenozoic basin fill in the Hayfork basin from inversion of gravity data of the southern Klamath...
Portable Raman spectroscopic analysis of bulk crushed rock Portable Raman spectroscopic analysis of bulk crushed rock
This study presents a simplified method and empirical relationships for determining organic matter thermal maturity using a portable Raman system equipped with a 785 nm laser, for analysis of crushed, whole-rock samples. Several sets of rocks comprised of shale and coal samples with various mineralogical composition, thermal maturity, total organic carbon (TOC), and age were used to test...

This Geologic Map Schema (GeMS) database contains all the geologic map information used to publish the Preliminary Surficial Geologic Map of Leuhman Ridge and the Surrounding Area, Edwards Air Force Base and Air Force Research Laboratory, Kern and San Bernardino Counties, California, U.S. Geological Survey Open-File Report 2023-1014. This digital map database represents the general...
Collection of digital structure contour maps from previously published USGS studies Collection of digital structure contour maps from previously published USGS studies
Under the direction and funding of the National Cooperative Geologic Mapping Program (NCGMP) with guidance and encouragement from the United States Geological Survey (USGS), there has been a decadal strategic plan in place to call for geologic mapping across the nation. This call has been increasing the need for digital data that has not yet been made available. With such a demand...
Aeromagnetic Data and horizontal gradient maxima of Blythe, California, and Surrounding Areas in California and Arizona Aeromagnetic Data and horizontal gradient maxima of Blythe, California, and Surrounding Areas in California and Arizona
This data release provides access to an aeromagnetic survey and magnetization boundaries over Blythe, California and surrounding areas in southern California and western Arizona. The survey extends east of Joshua Tree National Park across the Colorado River and west over the Dome Rock, Trigo, and Plomosa Mountains in Arizona. The survey was flown north of the Chocolate Mountains Gunnery...
Gravity data and geophysical gradient data of the Stockton 30 x 60 minute quadrangle, California Gravity data and geophysical gradient data of the Stockton 30 x 60 minute quadrangle, California
This data release presents point data associated with the geologic and geophysical maps of the Stockton 30 x 60 minute quadrangle, California. Data include principal fact information for new gravity measurements collected by the U.S. Geological Survey from 2015 to 2018 and for existing gravity data. Gravity and magnetic gradients were also calculated in the Stockton 30 x 60 minute...
Aeromagnetic Data and horizontal gradient maxima of Garlock, California, and Surrounding Areas in California Aeromagnetic Data and horizontal gradient maxima of Garlock, California, and Surrounding Areas in California
This data release provides access to an aeromagnetic survey and magnetization boundaries over Garlock, California and surrounding areas in southern California. The survey extends from the city of Bakersfield across the southern Sierra Nevada and Tehachapi Mountains and west over Indian Wells Valley and the towns of Mojave and Rosamond to just northwest of the town of Barstow. These data...
Digital database of the previously published geomorphic-structural map of the Ouachita Mountains Digital database of the previously published geomorphic-structural map of the Ouachita Mountains
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...
Zircon U-Pb data for ash-fall tuffs and sandstones of the Cenozoic Amargosa Valley and Bat Mountain Formations exposed on Bat Mountain, southern Funeral Mountains, California, USA Zircon U-Pb data for ash-fall tuffs and sandstones of the Cenozoic Amargosa Valley and Bat Mountain Formations exposed on Bat Mountain, southern Funeral Mountains, California, USA
This document includes two suites of zircon U-Pb data that establish a detailed chronostratigraphy for Cenozoic strata exposed on Bat Mountain of the southern Funeral Mountains, California, USA. The first suite of data includes detrital zircon U-Pb age distributions that characterize the maximum depositional age and provenance of five sandstone samples from the Oligocene-Miocene Amargosa...
Digital subsurface database of previously published well tops, structural features, and contour maps of the Inyan Kara Group, Minnekahta Formation, Minnelusa Formation, Madison Group, and Deadwood Formation, Black Hills region, South Dakota and Wyoming Digital subsurface database of previously published well tops, structural features, and contour maps of the Inyan Kara Group, Minnekahta Formation, Minnelusa Formation, Madison Group, and Deadwood Formation, Black Hills region, South Dakota and Wyoming
This digital data release presents multiple previously published elements of the structural configuration of the Black Hills regional subsurface. The original data within this geodatabase is sourced from multiple U.S. Geological Survey Open File Reports into the hydrology of the Black Hills, stored on the USGS Water Mission Area NSDI Node (Driscoll, 1992; Strobel et al., 1999; Williamson...
Microfossil, grain size, and petrographic data for the Cabin Branch and Cabin Creek (Cappy Avenue) outcrops, Prince George's County, Maryland Microfossil, grain size, and petrographic data for the Cabin Branch and Cabin Creek (Cappy Avenue) outcrops, Prince George's County, Maryland
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...
