摘　　要：在对研究区晚侏罗—早白垩世索瓦组地层进行路线调查与剖面测绘相结合的基础上,对该地层进行了单剖面相分析和区域上的沉积相带划分。证实了在晚侏罗—早白垩世索瓦组沉积时期,研究区古地理特征具南高北低,西高东低的特点。By combining the route investigation and the section survey of Suowa formation form Late Jurassic to Early Cretaceous,it analyses the single section facies and divides the regional facies belts of Suowa formation.It＇s proved that,in the sedimentary period of Suowa formation from Late Jurassic to Early Cretaceous,the paleogeographical features are raise south and west side,lower north and east side.
