Data

Geochemical and isotopic data from the manuscript "Assessment of natural reference materials for U-Pb geochronology of grossular-andradite garnet" published in Geostandards and Geoanalytical Research. Table 1 is a summary of major and trace element geochemical characteristics of the three reference materials investigated in this study. Table 2 and Table 3 show the results of ID-TIMS analyses perfo

These data were collected to investigate how well wind speed and direction can be measured using a miniature sonic anemometer mounted in a joust configuration on a small uncrewed aircraft system (sUAS). Test flights occurred at a bog within Interior Alaska that was instrumented with an eddy covariance flux tower. Part of the tower's instrumentation was a highly accurate sonic anemometer which was

The East Pisco Basin is one of several forearc basins situated on the coastal plain of Peru between the Andean Cordillera and Peru-Chile Trench. During the Cenozoic, successive marine transgressions across the East Pisco Basin deposited sequences of Paleogene and Neogene age. Biochronologic studies suggest that a hiatus of approximately 12 million years (~32-20 Ma) separates the youngest Paleogene

These data include individual zip files which contain 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, Esri shapefiles of the locations of the drill hole collars, and .csv files of tabular data that were compiled from handwritten drill core logs. The dri

This product is a georectified and tonally balanced mosaic of aerial photographs collected in 1938 by the U.S. Bureau of Reclamation along the floodplain of the Colorado River in Mohave Valley region of Arizona, California and Nevada. This dataset is a primary resource for the development of a geologic map showing the floodplain and river channel characteristics along the Colorado River in Mohave

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 (10,000 sq mil

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 rubidium m

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 collected for an a

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 samples 84-6-1

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 structure,

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 provided in a zi

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-southeast of Ne
