The dataset consists of the input data, parameters, and results output from mineral resource assessment calculations.
Stillwater Complex, Montana: Logs of core drilled by Anaconda in the Benbow area, 1969 to 1973
This dataset includes pdf representations of drill core logs showing associated drill core information, a pdf of the explanation for the lithology and structure sections of the logs, a shapefile of the locations of the drill holes, and eleven individual .csv files of tabular data that was compiled from hand written drill core logs. The drill core is from the Stillwater Complex, Montana and was dri
Microbial Carbon and Nitrogen Metabolism Across a Late Pleistocene Permafrost Chronosequence
This data release includes all of the data presented in the peer-reviewed publication "Life at the frozen limit: Microbial Carbon Metabolism Across a Late Pleistocene Permafrost Chronosequence". We collected permafrost from a Pleistocene chronosequence (19 ka to 33 ka) to examine (1) changes in the functional genetic potential of extant microbial communities to metabolize polysaccharides, (2) shif
Structure-from-Motion photos and derived point clouds from bluffs, Miami Park, MI, 2019
Images were collected using an unmanned aerial system over the bluffs of eastern shore of Lake Michigan in Miami Park rural residential area, Allegan County, MI. Images were collected in four separate instances on July 9, August 10, September 1, and October 18, 2019 and cover similar extent. Images were collected to monitor active bluff erosion in the area. The images are presented here in zipped
Field, geotechnical, and meteorological data of the 22 March 2018 narrow cold frontal rainband (NCFR) and its effects, Tuolumne River canyon, Sierra Nevada Foothills, California
This data release includes information used to support the manuscript "Linking mesoscale meteorology with extreme landscape response: effects of narrow cold frontal rainbands (NCFR)". The included datasets and supplement include information related to the 22 March 2018 NCFR and associated shallow landslides in the Toulumne Canyon triggered by this event. The three datasets and one supplemental inf
Field measurements of rainfall and soil moisture data used to support understanding of infiltration and runoff following the 2007 Canyon Fire, Malibu, CA, USA
This data release includes information used to support interpretations of relations between precipitation and soil moisture for a U.S. Geological Survey post-fire monitoring array installed near Malibu, CA following the 2007 Canyon fire. The 3 datasets are: 1) a time series of precipitation from three tipping bucket rain gages in individual files (Schmidt_2020_CANVQRG1.csv, Schmidt_2020_CANVQRG2.c
Stillwater Complex, Montana - Logs of core drilled by AMAX, 1969 to 1977
This dataset includes pdf representations of drill core logs showing associated drill core information, a pdf of the explanation for the lithology and structure sections of the logs, a shapefile of the locations of the drill holes, and sixteen individual .csv files of tabular data that was compiled from hand written drill core logs. The drill core is from the Stillwater Complex, Montana and was dr
High-Resolution Airborne Radiometric Survey of Mountain Pass, California
A detailed airborne 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 a 1-km interval with a flight-line
Density and magnetic properties of selected plutons (granitoids) in the Great Basin, parts of California, Nevada, Oregon, Utah, and Arizona
The U.S. Geological Survey (USGS) collected over 1,840 physical property measurements on selected plutons in the Great Basin, primarily in California and Nevada. Data include station identifier, geographic coordinates, rock type, density, magnetic susceptibility, remanent magnetization, declination, and inclination where available. Data are presented in ASCII format and include density and magneti
Geochronologic data from xenoliths near the Stillwater Complex, Montana
The Archean Stillwater Complex, a layered ultramafic-to-mafic intrusion, is exposed along the northern side of the Beartooth Mountains in Montana. To the north of the Stillwater outcrops, a gravity anomaly is located where Phanerozoic rocks may unconformably overlie the complex. These Phanerozoic rocks are intruded by Cretaceous plutons that have gabbroid inclusions that look like metamorphosed ro
Lithium Occurrences and Processing Facilities of Argentina, and Salars of the Lithium Triangle, Central South America
The "Li_Triangle_ARG_MRP_NMIC.gdb" geospatial database was developed by the U.S. Geological Survey for use in a geographic information system (GIS) to support mineral resource research and assessment of lithium resources in the Argentina portion of the central South American Lithium Triangle. The Lithium Triangle is host to significant amounts (nearly 60%) of the worlds known (identified) resource
Airborne electromagnetic and magnetic survey data, Stillwater Complex, Montana, May 2000 (ver. 2.0, June 2020)
A helicopter-borne electromagnetic/magnetic survey was flown over the Stillwater area, southwest Montana from May 5 to May 16, 2000. The survey was conducted over the Stillwater Igneous Complex, a Precambrian layered mafic-ultramafic intrusion which is characterized by igneous layering. Electromagnetic data were acquired using DIGHEM helicopter-borne electromagnetic system. Magnetic data were coll
