松辽盆地南部孤店逆断层活动性研究

Gudian Thrust Fault Activity Research in Southern Songliao Basin

通过地层去压实校正使地层厚度恢复到沉积时期的厚度,根据地层古厚度计算出孤店逆断层不同时期的落差和生长指数。研究表明,营城组沉积时期孤店逆断层活动强烈,到泉头组沉积时期其活动性降低,嫩江组沉积末期孤店逆断层发生反转。

Through the strata to the compaction correction to return to the thickness of sedimentary strata of the thickness of the period,according to the ancient stratigraphic thickness calculated Gudian thrust fault at different times of the gap and the growth index.Studies have shown that during the deposition of Yingcheng, Gudian thrust fault activity is strong,to the spring of their activities during the deposition of the first group have reduced the deposition of the late Nenjiang Gudian thrust fault reversed.
