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
