In the last stage of Late Pleistocene, the sedimentary environment in the China continental shelf region was mainly cold and dry. The environment changes were due to monsoonal circulation brought about by the Mongolion High Pressure. Dunes and loess deposits and several sandy geomorphologic types comprised the sedimentary environment. The primary characteristics of sedimentation was desertization and occurrence of its derivative deposits. The main evidences of desertization deposits are: endless erosion surface, large range of mixed deposits, universal "angle of repose" texture, dune type deposits, long distance interface of the most intense desertization and slightly intense desertization.
