Exposure ages of glacial deposits in the Prince Charles Mountains, East Antarctica

Most samples come from moraines deposited during the last glacial maximum, approximately 12,000 - 20,000 yr B.P. The ages are based on concentrations of the cosmic-ray-produced nuclides Be-10, Al-26 and Cl-36. 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.
