中文摘要：

四川盆的热历史用一个 paleo 热流动方法在盆从地上凿穿基于 vitrinite 反射被重建。结果证明四川盆经历了一个相对低的热流动时期在早古生代，并且提高的paleo热流动，变化有象在 259 妈附近的 100 mW/m2 一样高的最大值的 6080 mW/m2 ，从开始对目的晚古生代早二叠，并且减少的paleo热流动从对晚二叠晚三叠纪，然后维持对将近稳定今日。在有广泛的 Emeishan 洪水暗岩或隐藏了爆发了在之间的暗岩的地方，晚古生代的 paleo 热流动相当高早并且晚二叠，例如四川盆的西南、东北的区域。根据 paleo 热流动的分发，这能被推断，尽管有 Emeishan 洪水暗岩的缺乏，东北四川盆被 Emeishan magmatic 活动也在 Dongwu 运动期间影响。另外，四川盆的热历史重建的结果为 Emaishan 披风羽毛的存在和发作提供 paleogeothermal 证据。

英文摘要：

Thermal history of the Sichuan basin is reconstructed based on vitrinite reflectance from boreholes in the basin using a paleo-heat flow method. The results show that the Sichuan basin experienced a relatively low heat flow period in the Early Paleozoic, and an elevated paleo-heat flow, ranging 60-80 mW/m^2 with a maximum as high as 100 mW/m^2 around 259 Ma, from the beginning of the Late Paleozoic to the end of the early Permian, and a decreased paleo-heat flow from the late Permian to the late Triassic, and then maintained nearly stable to the present. The Late Paleozoic paleo-heat flow was quite high where there were extensive Emeishan flood basalts or concealed basalts which erupted between the early and the late Permian, such as the southwestern and northeastern areas of the Sichuan basin. According to the distribution of paleo-heat flow, it can be inferred that, the northeastern Sichuan basin was also influenced by the Emeishan magmatic activity during the Dongwu movement though there was lack of Emeishan flood basalts. In addition, the results of thermal history reconstruction of the Sichuan basin provide paleogeothermal evidence for the existence and onset of the Emaishan mantle plume.
