摘要:

研究区的横向构造变换带根据其对区域构造分段作用的规模分为3个级别,分别控制了相邻区块的构造-沉积演化和构造线展布、构造样式与变形程度的差异;纵向变换带的特征主要表现为主逆冲断层和背斜系斜列分布、逆冲位移纵向斜列传递;构造变换带形成的主控因素主要与基底构造、先存构造、滑脱断层在走向和倾向上沿多层次滑脱的转变、沉积相和岩性差异以及挤压力的作用方式等有关;它的纵向分带、横向分段作用,控制了褶皱-冲断带不同区带、区段的变形样式,从而控制了油气勘探的有利构造分布。

Abstract:

The lateral tectonic transform zones in the fold-thrust belts at the southern margin of Junggar basin can be classified into three levels.They dominate the structural-sedimentary evolution,spreading of structural lines,structural pattern and deformation extent in the study area.While the vertical transform zones feature in echelon distribution of the main thrust faults and anticline systems. The main factors that control the formation of the la-teral and vertical tectonic transform zones are related to the basement structures,former structures,detachment faults,differences in sedimentary facies and lithology,and compression stress pattern and so on.They control the patterns of deformation in different areas and segments of the folded-thrust belt and the distribution of potential prospects in study area.

Key words: tectonic transform zone, main controlling factor, folded thrust belt, southern margin of Junggar basin
