Aeromagnetic and aeroradiometric data acquired over parts of Grant, Hidalgo, Luna, Sierra, and Socorro Counties, New Mexico Aeromagnetic and aeroradiometric data acquired over parts of Grant, Hidalgo, Luna, Sierra, and Socorro Counties, New Mexico
NV5 Geospatial, in collaboration with EDCON-PRJ, Inc. acquired high-precision airborne magnetic and radiometric data over southwestern New Mexico. Survey flight-lines were flown in an east-west direction and are spaced at 200 meters. North-south tie lines are spaced at 2000 meters. The survey contained 142,673 line-kms (88,650 miles) of data and covered an area of over 25,900 sq. km (10...
Grade and tonnage data for lithium, cesium, and rubidium pegmatite deposits Grade and tonnage data for lithium, cesium, and rubidium pegmatite deposits
Pegmatites are a major host of global lithium, cesium, and rubidium resources. However, the existing grade and tonnage dataset for lithium pegmatites that was published in 1992 does not represent the current industry parameters used to delineate resources. There are no existing grade and tonnage datasets for cesium and rubidium. We present grade and tonnage data for lithium, cesium, and...
Magnetotelluric and TEM Data from the Umatilla Indian Reservation Geothermal Resources Assessment: Phase 2, 2020 Magnetotelluric and TEM Data from the Umatilla Indian Reservation Geothermal Resources Assessment: Phase 2, 2020
This data set consists of 19 wideband magnetotelluric (MT) and 23 transient electromagnetic (TEM) soundings collected by the U.S. Geological Survey in June 2020 as part of the Umatilla Indian Reservation Geothermal Resources Assessment: Phase 2 project. Each MT station had 4 components, 2 orthogonal magnetic induction coils and 2 horizontal orthogonal electric dipoles. Data were...
Data Release for "Apatite and monazite geochemistry record magmatic and metasomatic processes in rare earth element mineralization at Mountain Pass, California" Data Release for "Apatite and monazite geochemistry record magmatic and metasomatic processes in rare earth element mineralization at Mountain Pass, California"
The dataset includes .csv spreadsheets which provide whole rock geochemical data for the alkaline silicate and carbonatite samples from which apatite and monazite were analyzed, as well as geochemical data collected via electron microprobe and laser ablation ICP-MS for the apatite and monazite mineral grains. Whole rock geochemical data were collected by SGS Labs, except carbonatite...
Gridded gravity, magnetic, and pseudogravity data of the Sierra Nevada, California and Nevada Gridded gravity, magnetic, and pseudogravity data of the Sierra Nevada, California and Nevada
This data release presents gridded data associated with the geologic and geophysical maps of the Sierra Nevada Digital Earth Science Atlas led by the California Geological Survey and U.S. Geological Survey. Grids are provided in ASCII and geotiff formats. Complete Bouguer and isostatic gravity data were gridded from nearly 29,000 gravity measurements to provide information on crustal...
Sediment Thickness Data in the Deep-Sea Basins of the Bering Sea Sediment Thickness Data in the Deep-Sea Basins of the Bering Sea
A raster grid of sediment thickness in GeoTIFF format (BeringSeaBasins-SedimentThicknessGrid.tif) of the Aleutian, Bowers, and Komandorsky Basins was created by merging GeoTIFF grids of the Aleutian and Bowers Basins and of the Komandorsky Basin, provided in other sections of this data release. The raster grid file, along with a corresponding CSDGM FGDC-compliant metadata file, is...
Argon ages near Parker, AZ, and Needles, CA Argon ages near Parker, AZ, and Needles, CA
Reported here are argon age data for samples collected to better understand lower Colorado River corridor landscape evolution, the history of the Colorado River, and define the age of geologic units being mapped. Samples of basalts, ashes, and sand were collected in the Cactus Plain southeast of Parker, AZ, the Whipple Mountain piedmont north-northwest of Parker, AZ and washes east...
Optical Petrography, Bulk Chemistry, Micro-scale Mineralogy/Chemistry, and Bulk/Micron-Scale Solid-Phase Speciation of Natural and Synthetic Solid Phases Used in Chromium Sequestration and Re-oxidation Experiments with Sand and Sediment from Hinkley, CA Optical Petrography, Bulk Chemistry, Micro-scale Mineralogy/Chemistry, and Bulk/Micron-Scale Solid-Phase Speciation of Natural and Synthetic Solid Phases Used in Chromium Sequestration and Re-oxidation Experiments with Sand and Sediment from Hinkley, CA
This data release contains macro and microscale datasets describing the abundance, valence states, and mineral residence(s) of chromium, iron, and manganese in natural and synthetic mineral mixtures used in laboratory experiments designed to simulate dynamic conditions in an engineered aquifer system [see Izbicki and Groover (2018) and Miller and others (2020)]. The landing page contains...
Fluorite Samples from the Western United States - The Ronald G. Worl Collection Fluorite Samples from the Western United States - The Ronald G. Worl Collection
This dataset describes fluorite- and manganese-bearing samples collected and compiled by USGS Commodity Specialist, Ronald G. Worl during the 1970's. The dataset corresponds to a physical collection of fluorite- and manganese-bearing samples re-established under the National Geological and Geophysical Data Preservation Program. The collection includes samples that were used in the...
Digital Elevation Model (DEM) Derived Topographic Indices Across Sequoia Groves in Sequoia-Kings Canyon National Park and Yosemite National Park Digital Elevation Model (DEM) Derived Topographic Indices Across Sequoia Groves in Sequoia-Kings Canyon National Park and Yosemite National Park
This dataset provides topographic indices derived from 1 m resolution DEMs for sequoia groves in both Sequoia-Kings Canyon and Yosemite National Parks. All mapped sequoia groves in Sequoia-Kings Canyon National Park and two groves from Yosemite National Park, Merced and Mariposa, are included. For each grove, aspect, slope, the stream network, height above nearest drainage (HAND), depth...
Soil data release of legacy data collected from a soil chronosequence in Northern Michigan Soil data release of legacy data collected from a soil chronosequence in Northern Michigan
In July 1992 soils were sampled from six dune fields in the northern Lower Peninsula of Michigan near Wilderness State Park, about 10 miles southwest of Mackinaw City. The dune fields represent a soil chronosequence, where all soil forming factors except time are held constant (climate, organisms, relief, and parent material). These sandy lake terrace soils are Entisols and Spodosols...
Soil data release of U.S. Geological Survey Bulletin 1590, collected across the Western United States between 1975 and 1983 Soil data release of U.S. Geological Survey Bulletin 1590, collected across the Western United States between 1975 and 1983
Early studies of soil formation highlighted several key factors that together determine the degree of soil pedogenesis, which include climate, organisms (including vegetation), topography, and parent material (Jenny H.; 1941; Factors of Soil Formation, a System of Quantitative Pedology; https://doi.org/10.2134/agronj1941.00021962003300090016x). A soil chronosequence is defined as a...
