摘要
该文用地质恢复法研究了内蒙古海拉尔盆地的拉张历史。结果发现:海拉尔盆地的拉张强度在平面上西强东弱,南强北弱;在纵向上可分为A,B,C,D四种不同的类型。拉张强度在一定程度上控制了盆地(断陷)中生油岩的发育。
Based on comparison of different methods, the authors deals with the extensional histories of Hailaer Basin using geological restoration method. It concludes that the extensional strength in the west and south is stronger than that in the east and north, and there are four types of extensional histories vertically in the basin. The extensional strength controlled the de-velopment of the source rocks in the basin.
