Data

This publication provides digital flight line data for a high resolution horizontal magnetic gradient and radiometric survey over the Ironton, Missouri area of southeast Missouri. Data were collected using a fixed wing aircraft with magnetometers mounted in the tail stinger and each wing tip pod and a fully calibrated gamma ray spectrometer. The survey took place out of the Farmington, Missouri a

The State Geologic Map Compilation (SGMC) geodatabase of the conterminous United States (https://doi.org/10.5066/F7WH2N65) represents a seamless, spatial database of 48 State geologic maps that range from 1:50,000 to 1:1,000,000 scale. A national digital geologic map database is essential in interpreting other datasets that support numerous types of national-scale studies and assessments, such as

Airborne electromagnetic (AEM) and magnetic survey data were collected during October 2014 in a 553-square-kilometer area that includes the East Poplar oil field on the Fort Peck Indian Reservation in northeastern Montana, USA. Data surround the town of Poplar and extend south into the Missouri River floodplain. Data were acquired with the SkyTEM301 transient electromagnetic helicopter-borne sys

We developed and tested a new method for in situ characterization of the types and distribution of inorganic particles in biopsied lung tissue from three diverse human subject groups using field emission scanning electron microscopy with an energy dispersive analyzer. Backscattered electron and secondary electron images of particulate matter in lung tissue were acquired. Inorganic particulate matt

Twenty-five ore and gangue mineral separates from the Miocene-age Goldfield and Tonopah epithermal Au-Ag deposits in southwestern Nevada were analyzed to determine the helium, neon, and argon (He, Ne, and Ar) isotopic compositions contained in fluid inclusions. Four mineral separates from the Butte Main Stage vein deposit and two from the Bingham pyrite-enargite vein deposits were also analyzed. F

Gravity data were collected from 2006 through 2015 to assist in mapping subsurface geology in the southern San Luis Basin, northern New Mexico. This report gives principal facts for 567 new gravity stations that were acquired to fill in gaps in the public gravity data coverage.

This dataset was collected by Leah E. Morgan in the Argon Geochronology Laboratory of the USGS in Denver, Colorado in 2015. The dataset contains full raw argon isotopic data for samples presented in the manuscript: Characteristics and 40Ar/39Ar Geochronology of the Erdenet Cu-Mo Deposit, Mongolia. Imants Kavalieris, Bat-Erdene Khashgerel, Leah E. Morgan, Alexander Undrakhtamir, Adiya Borohul. Econ

Time-domain electromagnetic (TEM) soundings were made in the San Luis Valley, Colorado to map the location of a blue clay unit as well as suspected faults. A total of 147 soundings were made near and in Great Sand Dunes National Park and Preserve. An additional six soundings were made near Hansen Bluff on the eastern edge of the Alamosa National Wildlife Preserve. The blue clay is a significant hy

The titanium concentrations were obtained from a data set that is called the "National Geochemical Survey." This data set, as well as its documentation, are available in U.S. Geological Survey Open-File Report 2004-1001 (https://mrdata.usgs.gov/geochem/doc/home.htm). The titanium concentrations were measured in 3,457 samples of stream sediments from the coastal plain of the southeastern United Sta

This dataset is related to a 2017 journal article by A. J. Pietruszka and L. A. Neymark titled "Evaluation of laser ablation double-focusing SC-ICPMS for "common" lead isotopic measurements in silicate glasses and minerals" that is published in the Journal of Analytical Atomic Spectrometry (doi:10.1039/c7ja00005g).

This dataset contains *.rdata files that contain model objects returned from the glm{stats} function (v.3.3.0) in R. for 258 models derived for selected wells in the conterminous United States. The models are generalized linear models with a binomial response variable (glm family set to binomial) for forecasting the probability of groundwater levels declining or maintaining below specified low thr

Mineral groups identified through automated analysis of remote sensing data acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) were used to generate a map showing the type and spatial distribution of hydrothermal alteration, other exposed mineral groups, and green vegetation across the northwestern conterminous United States. Boolean algebra was used to combine
