Based on the analysis and comparison of a number of Ro data,this study established maturity equations (Ro -H) of the Jiyang depression of both the Cenozoic and the Upper Paleozoic,through which the eroded thickness of the discontinuity surface between the Mesozoic and the Paleozoic in the Jiyang depression was restored.
与新生界镜质组反射率(Ro)值比较,济阳坳陷晚古生界Ro值整体上出现了显著的异常,通过对济阳坳陷大量的晚古生界Ro异常数据点与新生界Ro数据点的分析、比较,建立了济阳坳陷新生界成熟度方程(Ro-H方程)和晚古生界古成熟度方程,利用这些古成熟度方程,对济阳坳陷Mz/Pz间断面剥蚀量进行了初步恢复,研究结果表明东营凹陷、沾化凹陷、车镇凹陷Pz/Mz间断面剥蚀量分别达3。
