Abstract

1-Introduction In this research with application of petrofabric studies and Finite strain analysis quantitative changes of strain have been evaluated in the Gachsaran rock units in the hanging wall of Ramhormoz thrust fault. Thirteen samples were selected for strain analysis in the normal section to the Fault strike along natural trench in the study area. Porphyroclasts have used as strain markers for future strain studies. The results of petrofabric studies reveal a dextral component of shear in the study area. Results of strain analysis show relative relationship between amounts of strain and distance from the fault. Three dimensional analysis of Strain ellipsoid shows three axial oblate ellipsoid shape for Strain ellipsoid. Kinematic vorticity analysis in the XZ principal plane of Strain ellipsoid shows 0. 39Wk>0) (Passchier and Trouw 2005). Pure and simple shearing components contribute equally to the instantaneous flow at Wk=0. 71 (Law et al. 2004). There are several methods for determination of the Kinematic vorticity number. In this research kinematic vorticity analysis was made based on Rxz-θ nomogram (Bailey et al., 1999). Rxz and θ are strain ratio in the XZ principal plane of Strain ellipsoid and the angle between long axes of the Strain ellipsoid related to the reference line, respectively. Results show 0. 39
