Basic principles and methods of denuded strata comeback;

Study the Erosion Thickness Restoration of Qianjiang Formation in Qianjiang Depression;

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.

Based on thermal history reconstruction and estimation of eroded thickness, the maturation and stages of hydrocarbon generation have been investigated for the pre_Tertiary(mainly Permian) source rocks in South basin, the southern Yellow Sea.

There are many ways in seeking the eroded strata thickness by the method of apatite fission track length distribution.

In this article, technique of apatite fission track length, the seismic strata velocity method, R_o method, sound wave time difference method and geologic extrapolation are used to get the eroded strata thickness of Tertiary, Jurassic and Cretaceous in the Bohai Bay basin area.

Application of stratum structure extrapolation method in the multi-stage denudation thickness estimation of the Paleozoic in Tazhong Uplift;

Recovering denudation thickness by interval transit-time;

The authors estimated the Mesozoic stratigraphy denudation thickness and recovered the thermal evolution history of the main source rock by using the "seismic profile method","R_o method","matter balance method",and "sonic-time method".
