     Mylonitic acidic and mafic magmatic rocks are exposed in the Kervian area (about 40 km. Southwest of the Sagez in Cordestan provience). These rocks are engaged with the meta pellitic and carbonates throw the imbricate structures. Tow different age of Precambrian and Cretaceous already were supposed to these rocks respectively. This study presents structure and fabrics of these rocks and clears that, despite the real age, they belong to one unique sequence that ductilly deformed in northeasterly trending shear zone. Various shear sense indicators present southwest vergence.
