摘要
通过对青海察尔汗盐湖盐系地层中碎屑物的研究,发现有风积物存在。风积物的大量出现一般代表着湖水相对浓缩。盐系地层中光卤石层位于碎屑层之上及其超覆现象和“珍珠盐”的形成均与风的作用有密切关系。这对于盐湖地质理论研究及开展我国的找钾工作有一定意义。
Size analysis of the elastics mixed into the salt-bearing sequences in Qaerhan salt lake, Qinghai, from which the quartz particles are examined on surface textures, proves out aeolian sand, malan type-like loess, aeo-lian-offshore mixture, malantype-like——shallow mixture four types ofaeolian sediments except for littoral to shallow type.In studying densification of saline waters or evolution of salt-bearing sequence, it must be emphasized that the large bulk of elastics in the sequences can be in no way attributed to the desalination of the saline water .Contrary to that, a great quantity of aeolian elastics just marks the densification.Lapping of the carnallite beds of salt-bearing sequence over the clastic sequences or the others, as well as forming of the pearly halite, is relative closely to wind force.
