A glacial stage spanning the Antarctic Cold Reversal in Torres del Paine (51° S), Chile, based on preliminary cosmogenic exposure ages / C.J. Fogwill, P.W. Kubik.
Title: | A glacial stage spanning the Antarctic Cold Reversal in Torres del Paine (51° S), Chile, based on preliminary cosmogenic exposure ages / C.J. Fogwill, P.W. Kubik. |
Author(s): | Fogwill, C. J. Kubik, P. W. |
Date: | 2004. |
In: | Geografiska Annaler. Series A. Physical Geography. (2004.), Vol. 87A(2) (2004) |
Abstract: | Presents cosmogenic ¹⁰Be data from former ice limit in Torres del Paine. These indicate short-lived stillstand or readvance of Patagonian ice culminating at 12-15 kyr BP, with mean age of 13.2 ± 0.8 kyr BP. Glacier extended 40 km beyond present ice margin, within 15 km of presumed Last Glacial Maximum limits. Timing of glacier stage spans Antarctic Cold Reversal revealed in ice cores, implying glaciers in these latitudes out of phase with those in northern hemisphere, reflecting instead climate structure of Antarctica during last glacial-interglacial transition. |
