The Discovery of Deep Potassium and Lithium Resources in the Huangjinkou Anticline, Northeast of Sichuan

Important clues have been found for potassium prospecting in the Huangjinkou anticline of the northeast Sichuan Basin in the 1970s (Zheng et al., 2015; Lin et al., 2004). In 2008, China Geological Survey launched a prospective investigation of potash resources in the western region of China, and the local governments and private-owned enterprises also responded positively. Then, during 2015−2016, the Land and Resources Department of Sichuan Province deployed potash prospecting drilling (borehole ZK601) in the Huangjinkou anticline, and obtained deep potassium and lithium resources. These results may give a direction of marine potash prospecting in the Sichuan Basin.
