Zonation of Structural Pattern in the Bozhong Depression and Its Adjacent Area
详细信息   
摘要
Based on structural assemblages and direction in map view, structural patterns in seismic profiles and Bouguer gravity anomaly in the eastern Bohai Bay Basin, the authors  propose that the Bohai Basin is characteristic of zonation of structural pattern.  Because the Tanlu fault cut through this belt, there developed many strike-slip faults and branch faults characteristic of string-shaped Bouguer gravity anomaly. The zonation of structural pattern is controlled by multi-phase tectonic movement related to development of the Tanlu fault, and this has an important effect on the distribution in the hydrocarbon in this area. The western and eastern horseback belts have become crucial target for hydrocarbon exploration due to their weaker movements and higher altitude.
