Analyses of historic U.S. Bureau of Mines samples for geochemical trace-element and rare-earth-element data from tin occurrences associated with the Ohio Creek pluton, south-central Alaska This report and digital data release presents 82 new rock geochemical analyses on historic U.S. Bureau of Mines (USBM) samples. These samples were originally collected by the USBM as part of their critical and strategic minerals project, which investigated tin occurrences associated with the Ohio Creek pluton, south-central Alaska. Historic USBM sample materials were retrieved by DGGS from the DGGS Geologic Materials Center (GMC), where the USBM samples were transferred as part of the federally funded Minerals Data and Information Rescue in Alaska (MDIRA) program in the late 1990s and early 2000s.
