摘要: 柴达木盆地盐湖干盐滩上分布有大面积的沙丘、沙垅、沙地,表面被盐壳覆盖,盐湖含盐系中掺杂有大量的风成砂。风成砂形成时代最早为中更新世晚期,晚更新世晚期至全新世为盐湖中风成砂形成的鼎盛时期,也是整个柴达木盆地沙漠化过程的主要时期

Abstract: There is vast expanse of sand dune fields,dune ridges and sand sheet distributed around the salt lakes in the Qaidam Basin. And the salt deposits in the lakes also contain a large quantity of windblown sand.Researches showed that the earliest deposition of windblown sand in the lakes occurred in the late period of mid-Pleistocene and it reached a high-peak period between late Pleistocene and Holocene. This is also consistent with the development processes of desertification in the Qaidam Basin.

Key words: Salt lake, Windblown sand, Qaidam Basin
