Schmidt Hammer Exposure Age Dating

Our results suggest that many of the relict rock glaciers in central and eastern Austria were formed over a long period during the Lateglacial and Holocene period.

Google Scholar Kaufmann V, Ladstädter R, Kienast G 10 years of monitoring of the Doesen rock glacier Ankogel group, Austria — A review of the research activities for the time period — Proceedings of the Fifth Mountain Cartography Workshop, Bohinj, Slovenia, March 29—April 1, An analogue N-type Schmidt-hammer proceq was used for measuring the surface strength of stable blocks at the rock glacier surface by recording a rebound value R-value of a spring-loaded bolt.

The R-value gives a relative measure of the surface hardness and hence time since exposure to weathering. Mean R-value differences of The differences between the lowest and the highest R-value at the rock glaciers itself were The differences in R-values between the talus slopes and the uppermost Schmidt-hammer site at the rock glacier were No high-quality age control points are available at the studied rock glacier. Therefore, an age-calibration curve cannot be established. An age-calibration curve for gneiss has been established previously for a rock glacier c.

This allows the estimate that the rock glacier formation period in the study area stretched over a period of several ka. Not unlikely, the formation of the rock glaciers was initiated already during the Gschnitz stadial Heinrich 1 ice rafting event dated to
