Session Details

Cosmogenic nuclides have proven to be an amazingly versatile tool for the dating of landforms, deposits and in consequence events of the Quaternary period.
We envision this session as a format for active discussion on both established and new approaches to dating landforms, as well on fundamentals of calculation parameters from cosmogenic nuclide data. Presentations on cosmogenic nuclide methods of all kinds are encouraged, including but not limited to:
1. Dating approaches:
• dating boulders vs. amalgamated clasts vs. individual clasts vs. sand or gravel from alluvial landforms, also with respect to depth profiles;
• exposure dating quasi-active landforms such as active slope instabilities, active periglacial landforms (rock glaciers);
• approaches to dating deeply buried sediments with burial dating or isochron dating.
2. Methodological aspects:
• fundamental age calculation parameters, such as production rates, scaling parameters, depth profile shape (etc….);
• improved chemical separation techniques for Be, Al, and Cl which lead to better currents at the ion source;
• progress of the various laboratories in ¹⁴C quartz extraction systems;
• novel combinations of minerals and/or nuclides for dating or erosion rate determinations.
In this session we would like to bring together researchers interested in the ways that cosmogenic nuclides ³He, ¹⁰Be, ¹⁴C, ²¹Ne, ²⁶Al, and ³⁶Cl are used in geochronology.
