摘　　要：上天梯膨润土矿位于昆仑—秦岭地槽褶皱带东延部位,大别山隆起北侧,是火山岩受不同水介质、不同物理化学条件的作用形成。通过分析区内矿床地质特征和测试矿石阳离子的碱性系数,矿区内的膨润土矿床分为钙质和钠质类型,并对不同类型矿床成因进行了探讨,指出区带上中、新生代盆地及中性、酸性火山岩分布区,具有进一步的找矿前景。The upper ladder bentonite mine is located in the eastern extension of the Kunlun-Qinling ground trough fold zone,and in the north of the Dabie Mountains Rise,which volcanic rock is formed by the action of different aqueous media and different physical and chemical conditions.By analyzing the geological characteristics of the deposit and testing the alkaline coefficient of ore cation,the bentonite deposits are divided into calcium and sodium types,and discusses the origin of different types of deposits,and points out that the middle and Cenozoic basins and neutral and acid volcanic distribution areas in the zone have further prospecting prospect.
