摘要
滇东南含铝岩系为上二叠统吴家坪组(龙潭组)底部和第四系,铝土矿床类型分原生沉积型和第四系岩溶红土堆积型两大类,成矿物质分别来源于峨眉山大火成岩省的基性玄武岩的风化、剥蚀、淋沥所形成的含铝土矿碎屑—红土物质,以及邻近的原生沉积型铝土矿的风化残积、残坡积。
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.
