摘要
云南文山地区是滇东南的重要铝土矿成矿区带。关告—煤碳湾铝土矿主要赋存于上二叠统吴家坪组(P3w)地层中,矿床类型为原生沉积型铝土矿。分别从铝土矿的含矿岩系、古地理沉积相、气候、基底不整合面等方面分析了关告—煤碳湾铝土矿的成因,并总结了铝土矿的找矿标志,为今后在关告—煤碳湾地区进行地质找矿工作提供了一定的地质依据。
Wenshan area is an important bauxite metallogenic belt in southeastern Yunnan Province.Guangao-Meitanwan bauxite deposit is mainly hosted in the Upper Permian Wujiaping Formation(P 3w)strata,the deposit type is primary sedimentary bauxite deposit.The genesis of Guangao-Meitanwan bauxite deposit is discussed from the aspects of ore-bearing rock series,paleogeographic sedimentary facies,climate,basement unconformity and so on,and the prospecting criterias for the bauxite deposit are summarized,so as to provide reliable reference for the geological prospecting in Guangao-Meitanwan area in the further.
