| 摘 要： | 渤海沿岸盆地东濮凹陷内发育的“高阻红”地层的地质时代归属和划分对比问题长期以来一直存在争议。通过区域地层对比、黏土矿物同位素年龄测试、古生物分析和“高阻红”地层赋存状况等的分析,确认该区“高阻红”地质年代属早三叠世,它与华北地区中—西部广泛分布的下三叠统刘家沟组以及和尚沟组可以对比。

| Abstract: | The geological age, stratigraphic subdivision and correlation of the “High Resistivity Red Bed” in the Dongpu Depression,Bohai Sea Coastal Basin, has been an unresolved question. Based on regional stratigraphic correlation, K-Ar dating of clay minerals, and micropalaeontological data, the present paper proposes that the “High Resistivity Red Bed” is Early Triassic in age. It can be correlated with the Lower Triassic Liujiagou Formation and the Heshanggou Formation, which are widespread in the central-western North China Platform. |
