Late Quaternary glaciation of the Tianshan, Central Asia, using cosmogenic 10Be surface exposure dating

Journal Article


Abstract


  • Glacial deposits are present at the head of the ��r��mqi River valley, Tianshan, Central Asia. 10Be surface exposure ages of 15 boulders from three sites along a 12��km valley transect range from 9 to 21��ka suggesting emplacement by glacial retreat and advance commencing at the global last glacial maximum (LGM) and most likely abating in the early Holocene. Although the age spread for a given locality is not small, perhaps indicating post-depositional reworking, maximum ages per site are either coeval with or are post-LGM and inconsistent with previous pre-LGM electron spin resonance ages. �� 2009 University of Washington.
