| 摘 要： | 利用磷灰石裂变径迹反演计算了塔里木中部地区3口井志留纪以来的热历史。研究认为,塔中地区志留纪以来的大地热流变化不大,为56～62mW/m2。志留纪、泥盆纪大地热流较低,约为58mW/m2;石炭纪大地热流略有增高,二叠纪时大地热流可能达到62mW/m2;中生代期间,大地热流逐渐降低,中生代末约为57mW/m2;新生代期间,大地热流略有增高,现今大地热流约为60mW/m2。塔中地区的热历史与其构造演化史密切相关。

| Abstract: | Apatite fission tracks of the samples from the Wells TC1, TZ12 and TZ45 in central Tarim were measured and analyzed. Using the measurement data, the heat flow evolution history from the Silurian to the Cenozoic in these wells was studied by the method of inversion calculation. According to the results of inversion calculation, the heat flow did not change a lot from the Silurian, varying at the range of 56 mW/m2 to 62 mW/m2 in central area of the Tarim Basin. From the Silurian to the Devonian, the heat flow was smaller, about 58 mW/m2. The heat flow increased gently in Carboniferous and up to 62 mW/m2 in the Permian. In the Mesozoic, the heat flow decreased gradually, which was about 57 mW/m2 at the end of Mesozoic. The heat flow increased again slightly during the Cenozoic, which was about 60 mW/m2 in the present. Heat flow evolution history was controlled by the tectonic evolution in central area of the Tarim Basin. |
