In the vicinity of Zunyi city, there occur potassium-bearing rocks of steady productive layer, good quality ores, widespread distribution, and rich amount of resource.

On basis of analysis of regional geology in the southern part of Shaanxi and distribution of potassium bearing rocks in the study areas, preliminary conclusion has been come that the rocks are all located around margins of a platform or a geosyncline, probably grouped into four types: detrital rock, volcanic lava, syenite and pegmatite.

The Dajinshan potassium bearing rock deposits is situated in the eastern end of the southern margin of North China Platform,the potassium bearing stratum preserves in the Ruyang Group of middle Proterozoic.

The shale could be broken directly prior to being utilized for agricultural purposes,based on the measured contents of its rapidly available kalium and slowly available kalium, in the remote area of Guizhou where there is abundant in the resources of shale containing kalium.

It is found that the accumulative potash terrane thickness from 2400 m to 3600 m of the basin is about 100m by the composition analysis study of extrinsic feature and energy spectrum element on the tertiary debris with potash in Xinjiang Kuche basin with electron microscope.
