摘　　要：通过对漠河盆地南缘地层层序、构造特征等进行的实际地质调查,认为漠河盆地南部盖层主要为中侏罗统的河流相、河漫滩相、湖相沉积岩以及上侏罗统和白垩纪火山岩,盆地南部受拉张作用影响,正断层、铲形断裂发育,盆地南缘具断陷盆地特征,盆地形成时间较长.同时厘定出漠河盆地南部边界位于绣峰林场二支线附近.With field geological survey, the stratigraphic.sequences and structural characteristics of the southern margin of Mohe Basin are studied. The result shows that the south of the basin is covered mainly by Middle Jurassic fluvial and lacustrine sedimentary rocks and Upper Jurassic and Cretaceous volcanic rocks. Affected by the extensional process, normal faults and spade faulting are developed in the south of the basin. The southern margin of the basin has the characteristics of fault-depression basin. The basin is formed in a long course. The southern boundary of the Mohe Basin is also determined by the study.
