Digitized sonic velocity and density log data of Sacramento Valley, California Digitized sonic velocity and density log data of Sacramento Valley, California
Sonic velocity and density well logs in the Sacramento Valley 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 transit times and bulk density measured downhole in oil and gas wells in the region. Sonic velocity and density data were also...
Gravity, aeromagnetic, magnetic potential, and physical property data of the Bartlett Springs fault zone and surrounding areas, California Gravity, aeromagnetic, magnetic potential, and physical property data of the Bartlett Springs fault zone and surrounding areas, California
This data release contains principal facts of gravity measurements collected by the U.S. Geological Survey in 2020-2022, a compilation of existing and new density and magnetic susceptibility data, and gridded magnetic and magnetic potential data of the Bartlett Springs Fault Zone and surrounding areas, northern California. These data support modeling of gravity and magnetic anomalies to
Gravity data of southern Washoe County and adjacent areas, Nevada and California Gravity data of southern Washoe County and adjacent areas, Nevada and California
This data release provides principal fact information of gravity data collected and compiled in southern Washoe County, Nevada and adjacent areas in Nevada and California. These data were collected from 1983 to 2011. Data were collected as part of a larger effort by Washoe County, University of Nevada, Reno and the U.S. Geological Survey to investigate the crustal structure of the region...
Aeromagnetic and derivative gridded data, and magnetization boundaries of northeastern California Aeromagnetic and derivative gridded data, and magnetization boundaries of northeastern California
This data release contains gridded aeromagnetic data from a dataset that merges two aeromagnetic surveys of northeastern California. Data from the Alturas and Burney surveys were gridded and merged to provide a continuous, detailed aeromagnetic dataset of the region. The merged dataset was then corrected for the inclination of the Earth's magnetic field (reduced to pole or rtp); match...
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...
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...

Aeromagnetic map of Burney and the surrounding area, northeastern California Aeromagnetic map of Burney and the surrounding area, northeastern California
An aeromagnetic survey was conducted to improve understanding of the geology and structure in the area around Burney, northeastern California. The new data are a substantial improvement over existing data and reveal a prominent north northwest-trending magnetic grain that allows extension of mapped faults, delineation of plutons within the Mesozoic basement in the northern Sierra Nevada...

Influence of pre-existing structure on pluton emplacement and geomorphology: The Merrimac plutons, northern Sierra Nevada, California (USA) Influence of pre-existing structure on pluton emplacement and geomorphology: The Merrimac plutons, northern Sierra Nevada, California (USA)
In much of the western Cordillera of North America, the geologic framework of crustal structure generated in the Mesozoic leaves an imprint on later plutonic emplacement, subsequent structural setting, and present landscape morphology. The Merrimac plutons in the northern Sierra Nevada (California, USA) are a good example of the influence of pre-existing structure at a larger scale. This...

Depth to bedrock based on modeling of gravity data of the eastern part of Edwards Air Force Base, California Depth to bedrock based on modeling of gravity data of the eastern part of Edwards Air Force Base, California
We describe a gravity survey acquired to determine the thickness of basin-fill deposits (depth to bedrock) and to delineate geologic structures that might influence groundwater flow beneath the eastern part of Edwards Air Force Base, California. Inversion of these gravity data combined with geologic map and well information provides an estimate of the thickness of basin-fill deposits...

Santa Rosa's past and future earthquakes Santa Rosa's past and future earthquakes
Santa Rosa is no stranger to earthquakes. This northern California city was damaged several times in the late 19th and early 20th centuries by shaking from earthquakes, culminating in the devastating earthquake of 1906, whose rupture passed 20 miles to the west of the city on the San Andreas Fault. Then in 1969, Santa Rosa was again strongly shaken and buildings were damaged by a pair of...

Strike-slip fault interactions at Ivanpah Valley, California and Nevada Strike-slip fault interactions at Ivanpah Valley, California and Nevada
Ivanpah Valley is flanked by high mountain ranges, and represents one of the most imposing valleys of the eastern Mojave Desert. Its sinuous shape implies a complex origin as does the fact that it is not bordered by prominent range-front normal faults like valleys of the Basin and Range Province. In Addition, its deepest sedimentary basin is restricted to a small part of the valley near...
