Schmidt hammer exposure-age dating of periglacial and glacial landforms in the Southern Swiss Alps based on R-value calibration using historical data

As a contribution to the palaeoenvironmental history reconstruction of the Alpine periglacial domain, this study focuses on the Schmidt hammer exposure-age dating (SHD) of (peri-)glacial landforms using rebound-value (R</spa...
