Again, using cosmogenic 10 Be surface-exposure dating, Andersen and colleagues (Reference Andersen, Egholm, Knudsen, Linge, Jansen, Goodfellow, Pedersen, Tikhomirov, Olsen and Fredin 2019) found that boulders > 1600 m asl on the Reinheimen plateau, 20–40 km east of Øyberget, give a deglaciation age around 10.5 ka (global calibration dataset, Lal-Stone time-independent scaling scheme). more


Surface Exposure Dating – Kelsey Winsor -

12.05.2018 · Rockfalls and rock avalanches are a recurrent process in high mountain areas like the Mont Blanc massif. These processes are surveyed due to the hazard they present for infrastructure and alpinists. While rockfalls and rock avalanches have been documented for the last 150 years, we know very little about their frequency since the Last Glacial Maximum (LGM). more

Surface exposure dating with cosmogenic nuclides

Geomorphic method of geochronologic dating that uses lichen growth to determine the age of exposed rock, based on a presumed specific rate of increase in radial size over time. Measuring the diameter of the largest lichen of a species on a rock surface can therefore be used to determine the length of time the rock has been exposed. Wikipedia more
