Assessment tract permissive of potash-bearing brine in China
|Deposit type||potash-bearing brine|
|Basin type||continental closed basin|
|Geologic unit||not identified|
|Notes:||Quaternary alluvial, lacustrine- and playa-related sediments of the Qaidam Basin likely to contain or be underlain by potash-bearing surface and subsurface brines.|
|Known K sites?||Yes|
|Quality of information||C: Commonly less than twenty sources of information are available, and detailed information is limited or much of the information is not tied to specific location.|
|Assessors||Greta J. Orris (USGS)|
|Qualitative assessment||R1: Tract contains known economic reserves, and at least some of the undiscovered resources are believed to be economic.|
|Tract delineation||The Qaidam tract consists of the part of the Qaidam Basin that may be underlain by potash-bearing brines. The tract was defined by Neogene to Quaternary alluvial, lacustrine and saline sediments as identified on a 1:1,000,000-scale geologic map of the Qinghai Province (Qinghai Bureau of Geology and Mineral Resources, 1991) and a figure showing the distribution of salt lakes in the Qaidam Basin (Chen and Bowler, 1986).|
