| Abstract: | The Upper Permian Wujiaping Formation, Lower Member of Longtan Formation and Quaternary are the Al - bearing rock series in Southeast Yunnan. The bauxite deposit can be divided into 2 types of original sedimentary deposit and Quaternary karst laterite accumulation deposit. The metallogenetic materials of them are separately originated from the bauxite - bearing fragment - laterite formed by weathering, denudation and leaching of basic basalt in the Emeishan Major Igneous Province or the weathering sedentary, sedentary - slope wash of nearby original sedimentary bauxite deposit. |
