Abstract :
Robat Zangijeh granitoidic pluton is located in the 85 Km of southwest of Bardscan and south of Zeber-Kuh mountains. The area is part of central zone of han in Tabas Block and mainly consists of granodiorite, monzogranite, syenogranite and granite. The most important textures are granular, micro-gramular-porphyritic, porphyrogranular, graphic, perthite and mylonite. In some part of the area different myrmekite textures, overgrowth of K-feldspars with albite and cross shape twinning are present and sphene is abundant mineral. Such a petrographic and location of samples in geochemical diagrams suggest the presence of metasomatism in the area. The intrusion located in a shear zone which is related to Niband fault and cataclastic and mylonitic textures could be evidence for the role of high pressure fluids during metasomatism.
