Abstract: The saline mineral resources which in Qinghai are very rich, the Chaidamu Basin which is known as goldmine is the permary rich areas that in saline mineral resources, which potential economic value accounted for about 97 percent of the thtal value, and have the objed advantage. The salt products that based on potash enjoyed a good reputation in China and abroad. We summed up the distribution laws of saline mineral resources which based on potash in Chaidamu Basin through analysis and reseaech the pervious geology materials, hoped it will play a role that use the little to get the big gology in finding mineral in the future time.
