High-Resolution Airborne Gravity Gradiometry, Magnetic, and Radiometric Data of Mountain Pass, Southeast Mojave Desert, California
A detailed airborne gravity gradiometry, magnetic, and radiometric survey of Mountain Pass, California was flown by CGG Canada Services Ltd. (CGG). The high-resolution helicopter survey was flown at a flight-line spacing of 100 and 200 m, a flight-line azimuth of 70 degrees, a nominal flight-line elevation above ground of 70 m, and consists of about 1,814 line-kilometers. Tie lines were spaced at
Geochemistry, geochronology, and isotope geochemistry data for rocks and zircons from Mountain Pass, California
This dataset contains geochemical, geochronologic, and isotopic data collected for rocks and zircons from Mountain Pass, California, USA. See accompanying Economic Geology publication described in the "Larger Work" section of this metadata file for a detailed description of this dataset.
Permafrost greenhouse gas and microbial data from the Alaska Peatland Experiment (APEX) 2017 to 2019
These data include permafrost gas concentration data from the Alaska Peatland Experiment at various depths, times, and locations
Enhanced Terrain Imagery of the Allentown 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution
This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Allentown 30 x 60 minute quadrangle in Pennsylvania and part of New Jersey. It also covers part of the Delaware River Basin. The source data used to construct this imagery consists of 1-meter and 2-meter resolution Lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acqui
Primary and supplementary data for estimating the the timing of crustal shortening and the initiation of left-lateral shear within the central Kunlun Shan, northern Tibet
This repository includes thermochronologic and geochronologic datasets generated for analysis and interpretation of the faulting history of the Kunlun Shan region of northern Tibet, as well as published timing of fault activity on other pertinent structures in the Tibetan Plateau.
Stillwater Complex, Montana: Logs of core drilled by Anaconda in the Nye Basin area, 1968 to 1982
This dataset includes TIFF (Tagged Image File Format) images of graphic drill core logs showing associated drill core information, a TIFF image of the explanation for the lithology and structure sections of the logs, an Esri shapefile of the locations of the drill holes, and fourteen individual .csv files of tabular data that were compiled from handwritten drill core logs. The drill core is from t
Thin section images of drill core from the Chrome Lake area in the Stillwater Complex, Montana
This dataset includes photographic images of thin sections of drill core from the Stillwater Complex, Montana, along with a shapefile representing the locations of the drill holes. The core was drilled in order to study contact-type copper and nickel sulfide mineralization in the Stillwater Complex. The images of the entire thin section, both in plane- and cross-polarized light, were taken using a
Thin section images of AMAX drill core from the Stillwater Complex, Montana
This dataset includes photographic and micrographic images of thin sections of drill core from the Stillwater Complex, Montana, along with a shapefile representing the locations of the drill holes. The core was drilled in order to study contact-type copper and nickel sulfide mineralization in the Stillwater Complex. See data release https://doi.org/10.5066/p9w5kp8u for accompanying drill log data.
Stillwater Complex, Montana: Logs of core drilled by Cyprus in the Chrome Lake area, 1971 to 1980
This dataset includes TIFF (Tagged Image File Format) images of graphic drill core logs showing associated drill core information, a TIFF image of the explanation for the lithology and structure sections of the logs, an Esri shapefile of the locations of the drill holes, and fourteen individual .csv files of tabular data that were compiled from handwritten drill core logs. The drill core is from t
Digital data from USGS OFR 83-250: Selected data for low-temperature (less than 90 degrees C) geothermal systems in the United States; reference data for U.S. Geological Survey Circular 892
The data in the csv and text files provided in this release are an update to the data tables originally published in USGS Open-File Report (OFR) 83-250 (https://doi.org/10.3133/cir892). Those data were published as paper tables and have until now only been available as pdf image documents that were not machine readable. USGS OFR 83-250 presented data for 2071 geothermal sites which are representat
Aeromagnetic data and design files related to testing of new drone-based magnetometer configurations and magnetic compensation software; 2020 Santa Cruz, CA, and Surprise Valley, CA
This dataset contains magnetometry data and design files related to testing of new drone-based magnetometer configurations and magnetic compensation software. Data were collected in Santa Cruz (CA) in September 2020 to compare two magnetometer systems that are flown with Unmanned Aerial Systems (UAS). Each system was flown using different suspension designs. To compare the systems and to characte
