RESTORATION OF THE WEST BOUNDARY OF THE LINQING DEPRESSION DURING LATE JURASSIC-EARLY CRETACEOUS AND ITS SIGNIFICANCE

In order to study the palaeo-tectonic setting of a basin,the location of the westboundary of the Linqing Depression during Late Jurassic-Early Cretaceous and its sedimentation are restored,on the basis of the data from seismic survey and drilling wells.Moreover,it is stiggested that the basin marginal facies in the belt of Weixixan-Huaiqiaois the favourable facies zone for hydrocarbon acccumulation.
