摘　　要：针对多期构造运动叠加盆地的特点,运用镜质体反射率建立了句容盆地三个构造层的古地温梯度,分析了各套古地温系统对地层剥蚀厚度赋存的特征。经与粘土矿物演化温度、裂缝充填物中的包裹体温度、苏北盆地古新统的古地温资料对比以及古地温梯度的成因分析,三套古地温系统符合句容盆地的构造演化史。在此基础上,估算了各构造层的地层剥蚀厚度。According to the features of multi - stage tectonic movement superposition basin, the paleo - geothermal gradient of three tectonic layers in Jurong Basin was established by using vitrinite reflectance data. It was analyzed the characteristics of thickness of eroded formation for each paleo - geothermal system. By compared with temperature of clay mineral evolution, temperature of inclusions in fracture filling and other paleo - geothermal data of Paleocene in Subei Basin, and causes of paleo - geothermal gradient, three paleo - temperature systems were accorded with structural evolution history of Jurong Basin. On these bases,it was estimated denudation thickness of each tectonic layer.
