LanpingSimao basin is the only known basin producing solid potash with its reserve probably to be increased as exploration goes forwards, providing supports in China’s crop production and security. This paper reviews published references regarding LanpingSimao basin in potash mineralization. 1) LanpingSimao basin is located within Tethys potash mineralization domain with only a small discovery Mengyejing sylvite mine with potential for large discovery; 2) Basin is composed of MesozoicCenozoic cap, with lower Triassic missing due to lift, middle to upper Triassic marine facies, Jurassic marine continental transitional facies, and Cretaceous and upper continental sediments; 3) The strata bearing potash is Mengyejing formation with sylvite and carnallite; 4) Br and δ11B、δ34SCDT、87Sr/86Sr imply a marine source, and less blended with continental and volcanic resource; 5) Its chemicals, potash mineralization source and age are similar with Thai Khorat basin whose major potash mineral is carnallite. This paper presents suggestion for exploration in Lanping Simao basin in further clarifying the source of potash and mineralization age and in boosting mode comparison with its adjacent potash areas.
