摘要

In this paper, the authors reveal the burial histories of four seismic profiles spanning Bachu uplift and present the tectono-thermal history of this region by solving two-dimensional heat conduction equation.  Then, the authors employ the principle of isostatics to compute the burial depths of Moho surface during geological period. Finally, the authors calculate the basal and surface heat flow of the basin. The numerical results show that the tectono-thermal history of this region can be divided into seven stages. The maximum of the geothermal gradient and heat flow appeared in Triassic period with the value of 32 ℃/km and 73. 6 mW/m^2_,  respectively, and the minimum of them appears now, the values are 20 ℃ /km and 46.4 mW/m^2_, respectively.
