Boroujerd granitoid pluton geologically is part of Sanandaj-Sirjan zone. Evidence of ductile deformation such as mylonitic fabric In most parts of the study area and changed Borujerd granitoid to mylonitic granite. Mylonitic fabric includes mylonitic foliation and stretching lineation is visible and , measurable at unweathered granite part. Most foliation are dipping low-to-moderate and changed 10-55 degrees. At north part of pluton foliation have NE-SW strike and in the south part of Boroujerd pluton chenged to NW-SE. At the north part foliation are dipping to SE and in the south part foliation are dipping to NE. stretching lineation are low angle plunging between o-25 to NW, NE and SE plunging. Due to the slope of the mylonitic foliation and shear sence indicator, normal and reverse dip-slip movement was determined for mylonitic granite. Collection of evidence in this area for tectonic setting determine of Boroujerd pluton show syn tectonic (Syn D2 deformation) emplacmet . After deformation and formation of mylonitic fabric in Boroujerd pluton, this pluton again deformed and Mylonitic and Stretching lineation arefolded.
