Continental Transpression Evidence Checking along the Fault Dena: Iran, Middle Zagros

Dena Fault is one of the fundamental and main structures with more than 130 km. One of the most important structural properties of this fault is changing in its trend so that at least three structural trends are detectable along this fault. Some continental transpression evidences along fault Dena are checked. These evidences are: Fold’s axis has configuration step and mutual desire. Fold’s axis average preferred orientation makes angles less than 45 degrees with preferred orientation of the boundary faults. Strike-slip faults are arranged overlapping and territory. P harmonic sections are more than harmonic sections R. In the central and southern parts the type is transpression Trust and in the northern part the type is transpression shear. In the present strike-slip component right lateral of this fault is dominant to its trust component and Fault function in the present era, is right lateral reverse.
