摘　　要：分析了焉耆盆地区域构造背景,认为盆地现今构造格局主要受近东西向(或北西西向)和北西向构造控制;在此基础上依据古地磁资料、盆地周缘张性构造、盆内张性构造、高地温梯度、沉积学特征判定焉耆盆地中生代原型盆地为伸展断陷型盆地。This paper analyzes the regional tectonic setting in Yanqi basin,and it is concluded that present tectonic framework is controlled by approximate east-west faults and north-west ones.Based on palaeomagnetic data,the periph-eral tensional structure,intrabasinal residual normal fault,high geothermal gradient and the characters of sedimen tary.Study shows that Yanqi Mesozoic basin is an extensional fault basin.
