摘　　要：查干哈达石膏矿含矿地层为一套内陆湖相红色碎屑岩系,石膏矿赋存于中始新统阿山头组(E_(2)a^(2)),呈近水平层状产出,石膏矿层与泥岩互层产出。初步认为石膏矿在相对封闭的环境下沉积而成,属内陆湖相蒸发盆地沉积成因。The strata of Chaganhada gypsum deposit is a set of red clastic rocks of inland lacustrine facies.Gypsum deposits occur in the middle Eocene Ashantou formation(E_(2)a^(2))in a nearly horizontal layer,and interbedded with mudstone.It is preliminarily considered that the gypsum mine was deposited in a relatively closed environment and belongs to the sedimentary origin of the inland lacustrine evaporation basin.
