Abstract:More than 10 maifanites deposits have been found in Shandong province, and “Taishan maifanite”, “Xuehuashan maifanite”, “Qingdao maifanite” are typical ones. They are weathered to semi-weathered hypabyssal rocks. Their chemical compositions are identical with ones of the typical maifanites deposits in Japan and China. Their major physical-chemical properties are dissolving, absorbing, in-out regulating, organic living-effect and repeating-use.
