استفاده از شیمی کانی آمفیبول برای دما- فشارسنجی گرانیتوئید بزمان، جنوب شرق ایران

The Bazman granitoid is located in the south margin of Lut block, and southeastern of Iran. It composed of granite, granodiorite, monzodiorite, quartz monzodiorite, diorite and gabbro. Plagioclase, feldspar, quartz, hornblende and biotite are the major minerals; sphen, apatite, zircon, magnetite and ilmenite are the main accessory minerals. Amphibole mineral chemistry is calcic in composition and is classified as actinolite and magnesio hornblende. These amphiboles are related to subduction and are consistent with proposed tectono-magmatic features for this granitoid (active continental margin related to subduction). Al-barometer accounts that pressure of amphibole crystallization is 1.06 to 4.13 Kbar. Hornblende-plagioclase thermometer shows 649 to 754 ºC for equilibrium of these two minerals. The estimated oxygen fugacity (-15.66 to -19.37) imply an oxidation magma and its formation convergent plate.
