Summary
Abstract: This data set consists of cosmogenic nuclide concentrations in samples from
bedrock surfaces in the Ford Ranges, Marie Byrd Land, West Antarctica. These
surfaces have been exposed by ice retreat since the last glacial maximum,
approximately 10,500 years ago. However, the majority of samples contain
nuclide concentrations indicating much longer and more complicated exposure
histories.

The primary data are concentrations of the cosmic-ray-produced nuclides Be-10
and Al-26 measured in quartz, and Cl-36 measured in K-feldspar, sample
locations, and the duration of recent exposure inferred from measurements on
co-existing glacial erratics. In addition, the data set contains detailed
information about the sites and samples, chemical compositions of the minerals
analyzed and compositions of the host rocks, as required to compute nuclide
production rates. This information is provided so that the data can be
re-interpreted if nuclide production rates or correction factors are revised in
future.
