摘　　要：下石炭统松喀尔苏组分布于卡拉麦里山南麓复背斜南、北两翼,搞清松喀尔苏组的岩性特征及其与上下层位的接触关系,可为该地区的油气勘探提供基础资料。东部双井子地区为陆相粗碎屑岩,与下伏的塔木岗组呈不整合接触;西部(老鹰沟东—五彩湾)为大套火山岩建造夹沉积岩。西部松喀尔苏组可分为下(C1sa,以火山岩为主)、上(C1sb,以沉积岩为主)2个亚组,2个亚组间呈整合接触。原五彩湾、尖山沟—沙丘河地区划为巴塔玛依内山组的地层应属松喀尔苏组下亚组。The Songkaersu formation of Lower Carboniferous is distributed in the south and north sides of anticlinorium in south piedmont of Kelameili mountain. To understand the lithological feature of it and contact relationship with above and beneath horizons can provide fun damental data for petroleum exploration in this area. The study shows that the eastern Shuangjingzi area occurs continental coarse clastic rock and unconformable contact with underlying Tamugang formation; the western Shuangjingzi area （i.e. east LaoyinggouWucaiwan area） appears large volcanic formation interbedded with sedimentary rock. The west＇s Songkaersu formation can be divided into lower subforma t/on （Cls, dominated by volcanic rock） and upper one （C1s by sedimentary rock）, they are in conformable contact. The Batamayineishan strata in original Wucaiwan area and JianshangouShaqiuhe area should belong to the lower subformation of Songkaersu formation.
