University of Isfahan Petrological Journal 2228-5210 3 11 2012 11 21 The study of minerals chemistry, thermobarometry and tectonic setting of plutonic rocks from Sarabi Tueyserkan area (Hamedan province) The study of minerals chemistry, thermobarometry and tectonic setting of plutonic rocks from Sarabi Tueyserkan area (Hamedan province) 39 58 16106 FA Ali Asghar Sepahi Garoo دانشگاه بوعلی سینا Kazem Borzoei Seddigheh Salami Journal Article 2016 06 14 Sarabi area of Tueyserkan is located in Hamedan province which is a part of Sanandaj-Sirjan zone. Rocks of the area include igneous and metamorphic types in which the igneous rocks vary from gabbro to granite. The gabbros include olivine-gabbro, gabbro-norite, norite and gabbro. Considering different methods of thermometry for gabbros, the highest temperature belongs to olivine-gabbros which is about 1300 °C and the least temperature is about 950 °C for mafic rocks. Clinopyroxene-plagioclase barometry suggests nearly 6 Kbar pressure. Clinopyroxene, biotite and particularly amphibole were used to determine magma composition and tectonic setting. The results suggest a calc-alkaline to tholeiitic magma with approximately high oxygene fugacity during crystallization in a VAB tectonic setting.
