Abstract:
This
data set consists of exposure ages for glacial deposits and glaciated
bedrock surfaces in the Ford Ranges, Marie Byrd Land, West Antarctica. Most
samples are glacially transported clasts exposed during the retreat of ice
since the last glacial maximum, 10,500 yr B.P. to present. There are a few
bedrock samples with longer and more complicated exposure histories. The
... ages
are based on concentrations of the cosmic-ray-produced nuclides Be-10 and
Al-26. The primary data are sample locations and exposure ages. Ages are
calculated using currently accepted nuclide production rates and correction
factors. The data set also contains all details of the chemical and isotopic
analyses needed to re-compute exposure ages if nuclide production rates or
correction factors are revised in future.
