Record #191648:

Edge-roundness of boulders of Torridonian Sandstone (northwest Scotland): applications for relative dating and implications for warm and cold climate weathering rates / Martin P. Kirkbride, Cara M. Bell.

Title: Edge-roundness of boulders of Torridonian Sandstone (northwest Scotland): applications for relative dating and implications for warm and cold climate weathering rates / Martin P. Kirkbride, Cara M. Bell.
Author(s): Kirkbride, Martin P.
Bell, Cara M.
Date: 2010.
In: Boreas. (2010.), Vol. 39(2) (2010)
Abstract: Describes inexpensive technique for differentiating boulder deposits of different glacial re-advance periods, usable as reconnaissance tool prior to boulder sampling for cosmogenic nuclides. Technique establishes relative chronology from changes to radii of curvature as boulder edges weather. Describes tests of a priori patterns of deposit age, using ¹⁰Be ages for verification. Demonstrates method by distinguishing between Wester Ross Re-advance (WRR) and Younger Dryas (YD) deposits using differences in boulder edge-roundness, and explores climatic controls on boulder weathering rates over the Last Glacial-Interglacial Transition. Results indicate rates of boulder weathering 2-5 times higher in glacial climates than during interglacials, with implications for exposure dating using cosmogenic nuclides.
