2013年3月第33卷第1期 四川地质学报 Vo1.33 No.1 Mar.,2013 2)雅布赖盆中生代为张扭断裂和张剪走滑断裂系,新生代为逆冲断裂(可能兼扭动)和逆冲断裂系。 在盆地与造山带接壤的区域普遍发育新生代山前冲断带和逆掩推覆体,这是盆地目前实现突破的重点勘 探区带。 参考文献: [1].甘肃省地质矿产局.甘肃省区域地质志[M].北京:地质出版,1989:244^一260.

Structural kinematics is modeled based on which na approach to the multiple structural superimposition,oil—gas migrationand accumulationaremade.
