MODELING OF BURIAL AND SUBSIDENCE HISTORY IN SICHUAN BASIN
四川盆地埋藏沉降史模拟

Based on the stratigraphic thickness, ages, lithosphere, porosity and seismic sections, the sedimentary and subsidence history can be obtained from subsidence curves by using backstripping analysis. The study indicates that the difference between the total subsidence and the tectonic subsidence in Sichuan basin decreases with the decreasing geological time, implying the small amount of compaction when the stratum is young. The subsidence rate is different in the various periods. The subsidence rate is large during the old time and become small as the time is running.
