The effects of a hydrogen-rich ground cover on cosmogenic thermal neutrons: Implications for exposure dating. Read Edit View history. Topographic shielding and shielding by snow, vegetation or soil is also taken into account. Cosmogenic nuclide samplng an erratic granite boulder with hammer and chisel on James Ross Island, January The basic principle states that a rock on a moraine originated from underneath the glacier, where it was plucked and then transported subglacially. In rock and other materials of similar density, most of the cosmic ray flux is absorbed within the first meter of exposed material in reactions that produce new isotopes called cosmogenic nuclides. Sample information and measured cosmogenic nuclide concentrations are listed in Table 1. We further report a first data set from a proglacial granite bedrock ridge in a small cirque in the Central Swiss Alps.
