The U.S. Geological Survey, California Volcano Observatory (CalVO) in collaboration with the State of California Governor’s Office of Emergency Services and the California Geological Survey, are working to understand the State’s exposure to volcanic hazards by integrating volcanic hazard information with geospatial data on at-risk populations, infrastructure, and resources. These data are from the geospatial analysis of the assets against volcano hazard zones (near vent, lava flow, lahar, flood, and ash fall) for California volcanoes ranked as Moderate, High, or Very High Threat in the US Geological Survey's 2005 report entitled “Volcanic Threat and Monitoring Capabilities in the United States” available on-line...

This data release includes 40Ar/39Ar data from the U.S. Geological Survey for samples from the Santa Cruz Basin, Arizona. Mineral samples were collected by Kenzie Turner and William Page from the upper Santa Cruz Basin, Arizona. Potassium-bearing mineral grains were separated from the bulk sample and analyzed by argon geochronology at the U.S. Geological Survey Argon Geochronology Laboratory in Denver, Colorado. The data provide age constraints on units in the relevant geologic mapping area.

Summary: Siliceous sinter samples were collected from multiple geysers in the Upper Geyser Basin of Yellowstone National Park in 2018. These silica sinter samples were collected and analyzed as a part of a multi-year research investigation into the age and geochemistry of hydrothermal features in the Upper Geyser Basin. Samples were collected along the stratigraphy of each feature. From these samples, we report 10Be, U-series, and 14C ages. Samples collected from Giant and Castle Geyser were further analyzed for their mineralogy, major and trace element concentrations, water content, and rare earth elements. This research was conducted under Yellowstone Research Permit YELL-2018-SCI-8030 and YELL-2018-SCI-5910....
