Argon data for Hugub Area, Kesem-Kebena-Dulecha, Ethiopia

Tephra samples were collected by Leah Morgan (now at the U.S. Geological Survey (USGS)) from the Hugub Area, Kesem-Kebena-Dulecha, Afar, Ethiopia. Sanidine grains were separated from the bulk sample and analyzed by argon geochronology at the Scottish Universities Environmental Research Centre, Scotland.

X-ray diffraction data of sediment samples from Hastings, Nebraska

X-ray diffraction (XRD) data was collected by the U.S. Geological Survey (USGS) in 2015 and 2016 on sediment core samples collected near Hastings, Nebraska, by the University of Nebraska at Lincoln (UNL) to inform aquifer sediment composition, mineralogical composition of operationally defined size fractions, and geochemical modeling. The sediment cores were collected near Ha
