///The Yitong Basin is an oil-bearing basin with unique property in eastern China. Based on apatite fission track analysis for 5 samples from Luxiang fault-depression and Chaluhe fault-depression and on the basin modeling study, it was concluded that since Oligocene (36.6 Ma), the Chaluhe fault-depression was undergone two tectonic events during 24.9 ~19.1 Ma and 6.9 ~4.9 Ma, and the Luxiang fault-depression was also undergone two tectonic events during 30 ~27.8 Ma and 22.6 ~11.1 Ma. Both of the two uplift events moved from centre to north of the Yitong basin since Oligocene. Plotting of apatite fission track ages versus elevations for each sample showed a good linear positive correlation in the Chaluhe fault depression and the Luxiang fault depression in the Yitong basin. These preceding research results on thermochronology analysis were supported by the evidence of earth dynamics, volcanic event, stratigraphic division and correlation, indicating that the technique of apatite fission track is feasible for analyzing the tectonic uplift history of the strike-slip and tension basin similar to the Yitong Basin.
