摘要: 松辽盆地北部断陷断裂分布呈现了东西分带、南北分块的构造特征,深层具有两隆三凹一斜坡的构造格局.在解释和分析大量的地震剖面的基础上,从断陷的形成和演化角度出发,建立起两种形成模式和两种类型四种演化模式.形成模式:箕状断陷、双断式断陷.两种类型四种演化模式:一种类型为发展型,包括加强式、扩展式;另一种类型为改造型,包括掀斜式、隆起式.松辽盆地北部断陷呈现幕式演化特征,整个演化过程可划分:初始张裂阶段、扩张阶段、萎缩阶段.

Abstract: The distribution of fault depression and fault in the northern Songliao Basin is seen in zonal arragemeng on WE direction and in blocky on NS direction.Deep structures show two more tracks, three fault depression tracks and one incline in the tectonic framework based on the formation and evolution of fault depression, two fault depression formation patterns and four evolution patterns are established by explaining and analyzing plenty of seismic profiles.The formation patterns include single fault depression and double fault depression.The evolution pattern include two types, one is developed type including strengthened pattern and expanded pattern, and another is modified type including titled pattern and upwelling denotation pattern.The fault depressions in the northern Songliao Basin have the characteristics of episodic evolution, and the whole evolution process of them can be divided into initial tension fracture stage, expanding stage and atrophy stage.

Key words: Songliao Basin, fault depression, tectonic characteristics, episodic evolution, fault depression pattern
