摘　　要：福泉白马山铝土矿是凯里—黄平铝土矿成矿带内的典型沉积型铝土矿矿床之一。对该铝土矿地质特征及控矿因素系统分析得出:矿体赋存于二叠系阳新统梁山组,呈似层状、透镜状产出于下奥陶统桐梓组古侵蚀面之上;矿石主要矿物成分为一水硬铝石,主要有致密状、碎屑状及豆鲕状三种矿石类型;赋矿地层、构造条件、古气候条件、岩相古地理条件等对铝土矿的形成有明显控制作用。The Baimashan bauxite deposit in Fuquan is one of the typical sedimentary bauxite deposits in the Kaili-Huangping bauxite mineralization belt.A systematic analysis of the geological characteristics and controlling factors of bauxite deposits in the area shows that:the ore body is located in the Liangshan Formation of the Yangxin Series of the Permian,appearing as a layered and lens shaped deposit on the ancient erosion surface of the Tongzi Formation of the Lower Ordovician.The main mineral composition of the ore is diaspore,which mainly includes three types of ore:dense,fragmented,and pisolitic.The formation of bauxite is significantly controlled by factors such as ore bearing strata,structural conditions,paleoclimatic conditions,and lithofacies paleogeographic conditions.
