Abstract

Geomorphic features and Pleistocene deposits on Huangshan have been attributed to glaciation. Recent reassessment questions this interpretation. Quartz sand grains from deposits identified as glacial boulder clays were analyzed by scanning electron microscope for evidence of their sedimentary history. Surface textures found on the boulder-clay grains were compared with those on grains with known sedimentary histories. The similarity with the colluvial grains and the outcrops'structures suggest an alluvial/colluvial origin for the deposits and points to warm climatic conditions in east-central China for at least part of the Pleistocene
