摘要
By combining the route investigation and the section survey of Suowa Formation from 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.
