摘要
The provenance and palaeocurrent direction of the Upper Cretaceous Nenjiang Formation in the northern Songliao Basin was analyzed by means of strata slicing in seismic-sedimentologic studies and combined with detrital and heavy mineral components tests.It was concluded that the deposition of the Nenjiang Formation was controlled by the eastern and northeastern deltas.The northeastern sources played important roles during the deposition of the 1st member of the Nenjiang Formation and the palaeocurrents were SN oriented along down-slop.The sedimentary model provides geologic support for petroleum exploration in Heidimiao reservoir in the north of the Songliao Basin.
