Abstract :

Fariman-Torbat-e-jam belt granitoidic pluton approximate (40km2) is located in capital of Razavi of khorasan province and 35 km of southeast Fariman city. This pluton intruded in perecambrian mikaschists and suffered a typical contact metamorphic rocks. The rock types consist of: diorite‚ granite‚ alkali granite‚ granodiorite‚ which formed of following mineral assemblages: quartz‚ alkali Feldespar‚ plagioclase‚ Biotite‚ amphibole‚ apatite‚ sphene‚ turmaline‚ Colorite‚ Opaque. In considerable phenomena that existences in this rocks can point on serisitizasion‚ sosoritizasion‚ caolinitizasion. also Mainly granular‚ porphyric‚ granophyric‚ rapakivi‚ pertite and antipertite textures is observed. disintegrate of high tempreture Fero magnesian minerals، catacelastic and milonytic texture‚ none linear trends in Rb-Sio2،Na2 o+K2o diagrams and descenty trend in Sio2 -Na2o diagram altogether are portend of metasomatism in this studied pluton.
