Digitized sonic velocity and density log data of Central Coast Ranges, California Digitized sonic velocity and density log data of Central Coast Ranges, California
Sonic velocity and density well logs in the Central Coast Ranges in California were digitized by hand. These logs are available as scanned files (pdfs and tiffs) on the California Division of Oil, Gas, and Geothermal Resources website and the data consist of interval transit times and bulk density measured downhole in oil and gas wells in the region. Sonic velocity data were also...
New U-Pb Geochronology and Geochemistry of Paleozoic Metaigneous Rocks from Western Yukon and Eastern Alaska New U-Pb Geochronology and Geochemistry of Paleozoic Metaigneous Rocks from Western Yukon and Eastern Alaska
This data release contains three tables of U-Pb zircon isotopic data generated from analyses of 40 metaplutonic and metavolcanic rocks from the Yukon-Tanana Upland of western Yukon and east-central Alaska and one sample from southern Yukon. One of the tables also reports U-Pb data for two titanite analyses for one of the samples. U-Pb zircon ages from analyzed samples range from 363.5...
Digital database for the geologic map of the Parker NW, Parker, and parts of the Whipple Mountains SW and Whipple Wash quadrangles, California and Arizona Digital database for the geologic map of the Parker NW, Parker, and parts of the Whipple Mountains SW and Whipple Wash quadrangles, California and Arizona
This geologic database is a digitized version of the 1:24,000-scale original analog geologic map titled "Geologic map of the Parker NW, Parker, and parts of the Whipple Mountains SW and Whipple Wash quadrangles, California and Arizona", published by the U.S. Geological Survey (USGS) in 1980. The map area straddles the Arizona-California border and includes the community of Parker, AZ...
Marine magnetic data from twelve cruises of Pioneer and Rehoboth in 1955 and 1956 off British Columbia, Washington, Oregon, and California Marine magnetic data from twelve cruises of Pioneer and Rehoboth in 1955 and 1956 off British Columbia, Washington, Oregon, and California
This shapefile contains total‐field marine magnetic data from eleven cruises of the USCGS ship Pioneer (OSS‐31) and one cruise from the USS Rehoboth (AGS‐50) in deep water off the west coast of the United States and southern British Columbia in 1955 and 1956. Magnetic anomalies are calculated with the latest definitive geomagnetic reference field (DGRF) included in the 12th Generation of...
Digital terrain model of upper North Fork Toutle River valley, Washington, derived from historical topographic maps Digital terrain model of upper North Fork Toutle River valley, Washington, derived from historical topographic maps
This digital terrain model represents historical elevations along the valley of the North Fork Toutle River upstream of its confluence with the Green River in Cowlitz and Skamania Counties, Washington. Most elevations were derived from U.S. Geological Survey 1:62,500 scale topographic quadrangle maps published from 1953 to 1958 that were derived from aerial photographs taken in 1951 and...
Phytostabilization in Polymetallic Tailings using Compost and Endophyte Additions Phytostabilization in Polymetallic Tailings using Compost and Endophyte Additions
Mining wastes can pose environmental hazards. These hazards can be mitigated by promoting the growth of native plants that can stabilize the mine wastes and potentially toxic elements in situ (i.e., phytostabilization). We grew a widespread perennial grass species (Bouteloua curtipendula) in dolomite amended polymetallic tailings from a historic mine in southeastern Arizona (USA). We...
Abiotic sorption of glucose, glutamic acid, hydroxybenzoic acid, and oxalic acid onto amorphous aluminum hydroxide, feldspar, ferrihydrite, and kaolinite Abiotic sorption of glucose, glutamic acid, hydroxybenzoic acid, and oxalic acid onto amorphous aluminum hydroxide, feldspar, ferrihydrite, and kaolinite
Abiotic sorption experiments were conducted with four carbon substrates (glucose, glutamic acid, oxalic acid, para-hydroxybenzoic acid) on four clay minerals (kaolinite, feldspar, ferrihydrite, amorphous aluminum hydroxide) after sterilization by gamma irradiation. The adsorption isotherms were carried across a range of substrate carbon concentrations (0, 20, 100, and 500 mg carbon per L...
Digital data documenting the evolution of Miocene normal and dextral faulting in the lower Colorado River region near Blythe, California, USA Digital data documenting the evolution of Miocene normal and dextral faulting in the lower Colorado River region near Blythe, California, USA
These datasets provide the measurements and analytical data used to describe the evolution of Neogene faulting near Blythe, California. The data include structural measurements and results from Ar-Ar and U-Pb geochronology that address the research questions of the associated publication. Structural measurement datasets provide fault surface kinematic measurements and tabulations of...
Stress transfer modeling of Great Basin, USA structural discontinuities; Data and MATLAB functions (ver. 1.1, June 2023) Stress transfer modeling of Great Basin, USA structural discontinuities; Data and MATLAB functions (ver. 1.1, June 2023)
This digital dataset contains the stress transfer modeling code (MATLAB functions) and folder tree needed to calculate stress transfer modeling on ten different common structural settings for hydrothermal systems in the Great Basin. Some of these functions were written or adapted from other published work. When this is the case the citation/location of the original code is noted in the...
Mapped polygons of landslides triggered by the 2016-2017 storm season, eastern San Francisco Bay region, California Mapped polygons of landslides triggered by the 2016-2017 storm season, eastern San Francisco Bay region, California
The winter rainy season of 2016-2017 brought abundant rainfall to the state of California, including the San Francisco Bay region. Thousands of shallow landslides were triggered as a result of saturated soils and intense rainfall from strong winter storms in January and February 2017. The highest concentration of landslides from these storms occurred in the eastern part of the bay region...
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...
Gravity Data in the eastern Mojave Desert, California and Nevada Gravity Data in the eastern Mojave Desert, California and Nevada
The U.S. Geological Survey (USGS) collected gravity data in the eastern Mojave Desert, California and Nevada as an aid to characterizing the regional geologic framework. Gravity stations were located between approximately lat 35°10’ and 35°50’ N. and long 115°05’ and 115°50’ W. and were distributed from west to east across parts of Shadow Valley, Clark Mountain Range, Mescal Range...
