摘要

 
    

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. The main factors which controlled the prototype of Bohu Depression during Jurassic depositional period were the structures in NE, NW and EW directions. 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.
