| 摘 要： | 根据不同剥蚀量恢复方法的特点和松辽盆地滨北地区实际地质情况,采用不同的方法对滨北地区T5和T4不整合面进行剥蚀量恢复。利用镜质体反射率法和体积平衡-沉积速率法相结合对T5不整合面进行剥蚀量恢复;应用镜质体反射率法、地层趋势分析法和沉积速率法相结合对T4不整合面进行剥蚀量恢复。研究结果表明T5不整合面因经历较长时间的剥蚀,剥蚀量较大,剥蚀量在700~2800m之间;T4不整合面剥蚀量多在200~1000m,在经历剥蚀时间较长的地区和靠近断陷盆地边缘的地区剥蚀量大。

| Abstract: | In combination with the characteristics of different erosion restoring methods and the geologic conditions of Binbei Area of Songliao Basin, different methods are deployed to conduct an erosion restoration of T_5 and T_4 unconformities in Binbei Area. The method of vitrinite reflectance is combined with the method of volume balance-sedimentation rate to have restoration to T_5 unconformaty, and the method of vitrinite reflectance is combined with stratum trend method and sedimentation rate method to have a restoration to T_4. The result shows that T_5 is of high erosion because of a long erosion period with erosion rate being between 700~2800m, the erosion in T_4 is at the most of 200~1000m.The erosion rate is the highest for longer erosion period and near the margin of the basin. |
