cosmogenic surface exposure dating-51

Integration of the snow-corrected exposure ages with field observations provided a detailed chronology of a progressive downwasting of ice from the maximum LGM ice volume with a gradual reorganization of the ice flow pattern and a southward migration of the ice divide.

In a study on the evolution and reorganization of ice streams entering the Weddell Sea, Antarctica, during the last deglaciation, ice sheet modelling was combined with in situ 14C and 10Be analysis.

In a study on the Gotthard Pass, Central Swiss Alps, in situ 14C-10Be exposure dating was combined with extensive mapping of glacial erosional features.

Data from both cosmogenic nuclides are in overall good agreement with each other confirming continuous exposure of the Gotthard Pass area throughout the Holocene.

The principles of dating sliding surfaces are more explained in the publication on the Oppstadhornet slide on Otrøya. 16.6 to 14.2 kyrs ago and past long-term displacement rates are in the order of 2 mm/yr.

Displacements rates measured today by differential Global Navigation Systems Satellite Systems (GPS) indicate the same velocity suggesting that the rockslide has been moving nearly constantly over the past 14 thousand years.

Surface exposure dating using terrestrial cosmogenic nuclides (TCN) is an established and reliable method to date landforms and has been applied for dating glacial advances and retreats, erosion history, lava flows, meteorite impacts, fault scarps, and other geological events.
