Geomorphological surfaces of different age and origin in granite landscapes : an evaluation of the Schmidt hammer test

Auteur :
ERICSON, K.

Description :
Granite landforms in Sierra Nevada, California, and the southern part of Sweden were used to test whether a Schmidt hammer can be used to distinguish surfaces of different age and origin. Based on 3620 readings, statistically significant differences were obtained from surfaces formes and/or affected by different geomorphological processes. Aeolian, fluvial or glacially polished surfaces yield higher values than surfaces exposed to surface weathering, which are distinguishable from surfaces at a weathering front caused by deep weathering.
