A DISCUSSION ON THE LOWER CRETACEOUS IN THE DUNHUA BASIN

Author information unavailable

Open publisher page 0 citations

Abstract

Previous researchers interpreted the Lower Cretaceous in the Dunhua Basin as detrital rock of fluvial or lacustrine facies based on outcrop observations. In this paper, by analyzing drillcore cutttings in the DunCan1 core, seismic data from sixteen 2D seismic cross-sections,and basin evolutionary stages, we came to the following conclusions: 1) the Lower Cretaceous in the Dunhua Basin exists in two types: epimetamorphic rocks in the main part of the basin and sedimentary rocks in other parts of the basin. 2) the scale of this Early Cretaceous basin is limited in a NNE narrow trough. 3) In the Early Cretaceous period,this basin was at the early rifting stage. 4) the Lower Cretaceous can not be targeted as a potential source rock.
