| Abstract: | Terrigenous sedimentary rocks developed with a great thickness in the rift basin of the South Jinxian Sag, Jizhong Basin, and stratigraphic framework is sandy sediments. On the basis of observing and describing the macro characteristics of the sandstones of detail, the mineral composition and texture of the Paleogene sandstones are studied by means of thin section and grain size analysis, and the provenance is roughly studied. We consider that the study of the change in the detrital composition of sandstones can be helpful to the analysis of the stratigraphic sequence. |
