Structural Overview of the Halab-Gheydar Area,Southwest of Zanjan,Nw Iran

Understanding the folding style of a fold-thrust belt is crucial to understand the nature and structural history of structures that may trap natural resources within the belt. in this research,the geometry and mechanism of a number of fault-related folds has been investigated based on field data and satellite image interpretations. the main study areas are: the sohrevard and ushtaniyan anticlines,bahman and halab synclines,and gharahdagh,halab,and gheydar thrust faults,which have a nw-se direction. these thrust faults control the morphology and structural framework of the halab-gheydar area. geomorphic features of the folds suggest that they are fault-related folds. the structural style of the faults and associated folds indicate that these faults were reactivated during the alborz deformation event.
