Exposure ages of glacial deposits, Reedy Glacier, Transantarctic MountainsEntry ID: 2008_REEDY_GLACIER_UW_COSMOGENIC_NUCLIDE_DATA
Abstract: This data set consists of exposure ages for glacial deposits on nunataks and ice-free areas adjacent to Reedy Glacier, Transantarctic Mountains. Most
samples are glacially transported clasts exposed during the last glacial period or by subsequent retreat of the glacier, ca. 16,000 yr B.P. to present. There are also data from a few samples from older deposits, which may have more complicated ... exposure histories. For these samples, the exposure ages indicated should be treated as lower limits. The ages are based on concentrations of the cosmic-ray-produced nuclide Be-10. The primary data are sample locations and exposure ages. Ages are calculated using currently accepted nuclide production rates and correction factors, as described in the footnotes. The data set also contains chemical and isotopic data needed to re-compute exposure ages if nuclide production rates or correction factors are revised in future.
