| 英文摘要 | The Tarim basin is a typical large-scale superimposed structure which developed on a Archean Early Proterozoic crystalline basement, with stable craton properties. Its present day surface heat flux is only 43 mW.m(-2), with average geothermal gradient 21 degrees C.km(-1) and Moho temperature 550 degrees C. The low heat flow background value indicates that this basin experienced a process of secular cooling and thickening. However, for such a secular cooling process, previous studies only concentrated on Phanerozoic stage and did not cover the entire thermal history of Tarim. In this paper, we use the thermal data of the Tarim area as a constraint, and set up the bottom boundary conditions according to different mantle dynamic models. Then, the background thermal history of Tarim is reconstructed by forward modeling, which fills the gap in the study of thermal history before the Palaeozoic in this region. The results show that the background heat flow of Tarim was decreasing (reduced from 85 mW.m(-2) to 43 mW.m(-2)) and the lithosphere was thickening (increased from 130 km to 190 km) continuously since the basin's formation. On a long time scale, the thermal evolution model of the Tarim craton is secular cooling and thickening, which is similar to that of other typical cratons in the world. While, under the influence of short-term local tectono-thermal events, the thermal history of the Tarim craton was superposed by about 20 similar to 40 mW.m(-2) thermal disturbance on the trend of secular cooling. |
