摘 要：The Qaidam Basin is a typically continental potash-bearing basin, which is comparatively rare in other countries. The potash deposits are widespread in the Quaternary salt lakes of the mid-western basin. At the same time, there exist many favourable conditions for the formation of potash deposits: (ⅰ)the sufficient source of potassium, (ⅱ) the optimum migration and accumulation processes of potassium, and (ⅲ) proper physico-chemical environments for separating potash salts. Owing to the differences in the supplying conditions for the external water to lake-basin and in the chemical compositions of those salt lake brines, potash deposits of various models and various types were formed.
