The Sanandaj-Sirjan metamorphic zone experienced a polyphase deformation history, which is related to Zagros orogenic belt. At North-West part of Sanandaj-Sirjan zone many Pegmatoied dykes intruded in Jurassic Phylite and Schist. These dykes have a various mineralogical composition and texture. Various zones such as Aplitic bearing graphic texture and enclave , corse grain pegmatite , layered pegmatite, Aplitice without enclave zones. Pegmatites contains Albite, alkali feldspar, tourmaline, quartz and muscovite minerals. At the top of the pegmatites Aplitic zone are formed that had enclaves with intergrowth of quartz and feldspar. According to the field observations and satellite images pegmatoieds dykes have often trend NW-SE trend and some of dykes N-S and NE-SW trends.These have yary length ,even more than one kilometer. They have variable thickness and has been viewed more than 10 meters. Dyke slip is variable but often high and almost vertical slip, but at a low angle dikes are observed at the field observations. Based on field studies and satellite images NW - SE trending dikes younger than other dikes and cut other trends of dikes. Internal structures of dikes clearly show e kinematics extension to formation of dykes. Internal structure such as orientation of tourmaline and layering are shown in these dykes. Tourmaline crystals oriented perpendicular to the wall and strike of dikes coresponding to the extension direction. Microstructure analysis of these dykes reveals these dykes are deformed. Quartz grain show migration boundary deformation and chess extinction. Deformation twining formed at the plagioclase. Other kinematic evidence are preserved in this area. Syn-taxial pegmatite veins, en echelon pegmatite vein and intersecting vein usually seen in this area. Some of vein are folded and some of veins are formed in multi stages. Orientation and deformation of dykes and other kinematic evidence suggested non coaxial progressive deformation for this area. Thi
