    dct:description "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 Hastings, Nebraska, and were collected, preserved, and processed by University of Nebraska at Lincoln (UNL)." ;
