The Yellowstone Plateau Volcanic field consists of lavas from the last two million years. The most recent volcanic units are the Central Plateau Member and the older Upper Basin Member rhyolites (Christiansen, 2001). Investigations into the elemental and isotopic composition of these lavas can provide insight into the recent volcanic history of the different eruptive episodes and provide constraints on the hydrothermal fluid compositions that result from water-rock interactions occurring at depth within the hydrothermal system. In this Data Release, seventeen samples of Yellowstone rhyolite samples from Upper Basin and Central Plateau Member lava flows were analyzed for volatile element compositions via x-ray fluorescence...
Mineral compositions are reported for Quaternary volcanic rocks of the Matan volcanic center, northern Harrat Rahat, Saudi Arabia. Compositions were measured by wavelength-dispersive methods with the 5-spectrometer JEOL-8900 electron microprobe at the USGS facility in Menlo Park, California; background-corrected X-ray intensities were reduced to oxide weight concentrations with the JEOL proprietary version of the CITZAF reduction schema. These results are part of a collaborative study by the U.S. Geological Survey and Saudi Geological survey to assess the volcanic and seismic hazards associated with the northern Harrat Rahat volcanic field.
The Yellowstone Plateau volcanic field and surrounding region is made up of over 3 billion years of geologic history, with 300+ separate rock types. To increase our understanding of the evolution of this active system and direct priorities for sample collection and field study, we compiled whole rock geochemical datasets from numerous thesis and papers (17 in total). We present these data in a standardized format and include location information and details on analytical methods when available.
The Yellowstone Plateau Volcanic field consists of lavas from the last two million years. The most recent volcanic units are the Central Plateau Member and the older Upper Basin Member rhyolites (Christiansen, 2001). Investigations into the elemental and isotopic composition of these lavas can provide insight into the recent volcanic history of the different eruptive episodes and provide constraints on the hydrothermal fluid compositions that result from water-rock interactions occurring at depth within the hydrothermal system. In this Data Release, twenty-one samples of Yellowstone rhyolite samples from Upper Basin and Central Plateau Member lava flows were analyzed for major and trace element concentrations and...

In this Data Release, seventeen samples of Yellowstone rhyolite samples from Upper Basin and Central Plateau Member lava flows were analyzed for strontium isotopic composition. Analyzed samples...
The data are the results of mass spectrometer experiments to measure 40Ar/39Ar ages of groundmass and mineral separates from volcanic rocks in northern Harrat Rahat, Kingdom of Saudi Arabia. The data were collected using a MAP216 noble gas mass spectrometer at the USGS facility in Menlo Park, Calif. These data were collected as part of a collaborative study conducted by the U.S. Geological Survey and Saudi Geological survey to assess the volcanic and seismic hazards associated with the northern Harrat Rahat volcanic field.
The data are the results of mass spectrometer experiments to measure 40Ar/39Ar ages of sanidine crystals hosted in Yellowstone rhyolites. The data were collected using a MAP216 noble gas mass spectrometer and a Nu Noblesse noble gas mass spectrometer at the USGS facility in Menlo Park, Calif.

This dataset represents a variety of scientific measurements of basalt rock outcrops in central Oregon, United States. It consists of field observations, geochemical measurements, paleomagnetic directional measurements, magnetic susceptibility, and geochronology data (Ar-Ar methodology). This dataset was collected from 2014-2022 by the authors.
