Structural modeling and structures related to mineralization in northeast Shahr-e-Babak

This article attempts to investigate the relation between mineralization and structural evolution of elements، while it is using field surveys and satellite image analysis in NE Shahr-e- Babak، which is part of Urmie-Dokhtar volcanic belt. Structural analysis indicates a close relationship presents between mineralization and structural evolution of elements in the region. T1، T2، R' and R fractures are the most important fracture types in the area which are resulted from the large scale folding and right- lateral faulting in the region. Analysis indicates riedel that the T2 extended fractures with an E-W trend are the oldest fractures in the area which are dependent to the folding and have been filled by magma forming dike swarms. At the second stage، R' fractures have formed which are dependent on the movement of faults in the area having NE-SW trends and left- lateral with normal kinematic component cutting the T2 fractural and porphyry copper deposit have formed at their intersection. Some other extended fractures in the area include T1 that is extended fractures with N-S trends in which valuable veins with isolated dikes have been emplaced. Riedel fractures dependent on anti-riedel shear fracture with NW-SE process lack filling and bare mineralization has been done in them. Structural analysis and offset fractures indicate that anti-riedel fractures have been formed before riedel fractures in right lateral transpression system which itself a reason for the uplift in the region. Hence، structural elements have had a direct impact on the mineralization in the region.
