Kuh-E-Faryadoon and Kouli Kosh iron deposits are hosted by regional metamorphic rocks of Sanandaj-Sirjan zone around Deh-Bid area. Plugs and domes of acid rocks protrude these metamorphic rocks. A mylonitization event is super imposed on acid rock and metamorphic complexes. Field, petrological and geochemical studies have shown that (1) Iron mineralization have occurred during mylonitization in...
To develop a novel and clean smelting process for the comprehensive utilization of Hongge vanadium titanomagnetite (HVTM), this work determined influence B2O3 on oxidation induration HVTM pellets (HVTMP). The degree, compressive strength, porosity, crystalline phase, microstructure, degree HVTMP were comprehensively investigated, relevant mechanisms discussed. results indicated that decreased p...
Eocene volcanic rocks in SW of Choupanan are exposed along the Choupanan fault as lava with andesite, trachyandesite to dacite composition and pyroclastic rocks. This area is a part of Central Iran (Yazd block). Andesite is the most predominant rock unit of the area and is composed of feldspars (andesine, oligoclase, and sanidine), amphibole (magnesio hastingsite, magnesian hastingsite, magnesi...
