摘要
冀中坳陷晋南洼陷古近系充填了巨厚的陆源沉积岩 ,其沉积骨架为砂岩。通过薄片分析 ,系统地研究了砂岩的物质成分和结构特征 ,以及重矿物、常量元素特征并初步进行了物源分析 。
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.
