Assessing the age-weathering correspondence of cosmogenic 21 Ne dated Pleistocene surfaces by the Schmidt hammer

Auteur(s) et Affiliation(s)



Description :
The AA. compare data obtained by both methods, Schmidt Hammer (SH) and Terrestrial Cosmogenic Nuclide (TCN), for c. 150 ka bp glacial and fluvial erosive granite surfaces from 2 study areas of northwest Spain. : Serra de Queixa-Invernadoiro with a lithology of alkaline two micas granite and O Pindo Massif developed on biotic granite. Rebound values (R) have been firstly compared with the rock density to assess the correlation with the rock strength, independently from influence of factors such as wetness and roughness in the R-values. Results show that age inferences exclusively based on R-values may not be realistic, but SH studies could be a useful tool for selecting surfaces for TCN dating.
