摘　　要：白水塘地区铝土矿赋存于上三叠统中窝组下部(T3z1～2),其分布在构造条件相对稳定的洼地,具一定时期的沉积间断。沉积相为局限海湾—泻湖—沼泽相。下伏地层为中三叠统北衙组灰岩。矿床成矿条件表明,该区具有一定的找矿前景。区内构造简单,古岩溶洼地对成矿有利。Baishuitang bauxite resides in the Upper Triassic Zhongwo Formation（T3z1~2）and can always be found on depression,where the structural setting is pediocratic,no-sequence is long.Sedimentary facies are gulf—lagoon—swamp.Underlying formation is the Middle Triassic Beiya formation limestone.There is a certain prospecting ore based on the analysis of the mineralization conditions.The structrue is simple in this area.The fossil karst depression is benefit for mineralization.
