焉耆盆地博湖坳陷侏罗纪盆地原型与成因机制
|
摘要
焉耆盆地博湖坳陷侏罗纪盆地原型存在诸多争论.在参考前人研究基础上,利用地震资料采用层拉平和平衡剖面技术对焉耆侏罗纪原型盆地进行恢复.研究结果表明,盆地在该时期为类前陆盆地.侏罗纪沉积期,博湖坳陷原型盆地主控因素是EW向、NE向和NW向构造.在NS向直压应力作用下,博湖坳陷中间地块向北推移,西部和东部地块分别向西南和东南运移,形成宝浪走滑断裂带、四十里城走滑断裂带和种马场隆起带,控制着坳陷沉积.
The prototype of Yanqi basin is of great contention owing to its complex geological background.On the basis of previous studies,the Jurassic prototype of Yanqi basin was restored by bedding flattening and balanced section technology.The results indicate that the basin was foreland basin during Jurassic period.The main factors which controlled the prototype of Bohu Depression during Jurassic depositional period were the structures in NE,NW and EW directions.Under the directly compressive stress of north-south direction,the middle block of Bohu depression moved to the north.At the same time,east and west blocks moved to the south.After that,Baolang,Sishilicheng strike-slip faulted zone and Zhongmachang uplift zone formed.They all controlled the deposition inside and around Bohu depression.
