Abstract

Detailed geological and structural analysis of north of TORUD-Moalleman area (Central Iran), between Anjilu fault in north and TORUD fault in the south, led to tectonic elements of this limit such as FRACTUREs and relative of their mechanism with left lateral sheared zone of two main faults. This study provides a movement system of Chalu, Gandi and Hafez faults in this shear zone. On the basis of kinematics findings and using general methods of fault slip analysis (orientation of slip plane, slip vector, shape of STRESS ellipsoid and angle of internal friction) region STRESS field were calculated after determining the angle of internal friction for each one of fault limits. Then, the main STRESS orientation determinates for combination data that values of s1, s2, s3 were 195/10, 339/78 and 104/07 respectively. The shape of STRESS ellipsoid was defined on the basis of shape factor, [R= (s2-s3) / (s1-s3)], (Angelier, 1975). The R-value for whole studied regions was about 0.5 and deformation type was mainly left lateral transpressional with reverse component. Such results are evident from N-NE (N195) trending s1 in the region and northward movement of the lithosphere. These finding are in line with field research results of FRACTUREs, faults and mechanism in this general shear zone.
