| 摘 要： | 依据海西期A型花岗岩,周缘张性构造,侏罗纪泛盆,高地温梯度,盆内张性角砾岩及残留正断层,沉积史特征,箕状断陷,古地磁等八个方面资料论证了中生代焉耆盆地处于转换一伸展状态；从区域重、磁场,大地电磁测深资料,塔里木、吐哈盆地基底最新研究成果等三个方面探讨了中生代焉耆盆地形成机制──拆离滑脱。

| Abstract: | Based on A-type granite in Hercynian period, the peripheral tensional structure, Jurassic extensive basin, high geothermal gradient, intrabasinal tensional breccia and residual normal fault, sedimentary evolution history,dustpan-like fault-depression and palcomagnetic data, this paper identified Yanqi Mesozoic basin's transition-extension state. The decoupling-detachment formation mechanism of Yanqi Mesozoic basin was discussed for three aspects as follows: regional gravity and magnetic data, MT data and the latest study on the basement of Tarim and Turpan-Hami basins. |
