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...

The Chalu Fe skarn developed at the contacts of the part of intrusive body with monzodiorite composition and Cretaceous carbonate rocks. Endoskarn which occurs in a limited area is characterized by andradite rich garnet (Ad90Gr5Sp3) and clinopyroxene. The calcic exoskarn shows a continuous mineralogical evolution and zonation with increasing distant from contact. It is composed mainly of coarse...

Senjedak II & III prospect areas are part of eastern anomalies of the Sangan mine, which is located in northwest of Khaf. The geology of the area consists of Pre-Cambrian schistes, Jurassic and Lower Cretaceous sedimentary rocks, and tuff and biotite monzonite porphyry intrusion with Eocene age. Skarn types in the Senjedak III include pyroxene–garnet skarn, garnet–pyroxene skarn, garnet skarn, ...

The study area is located about 30km northwest of Kashmar, southwest of Keriz village and east of Siah Kuh mine. Based on field and mineralogical studies, the rocks are mainly polutonic, sub-volcanic and volcanic, aged Eocene. The carbonate unit, with Permian age, is exposed extensivelly in the area. The mineralization in the area appears as veins, lenses, massive and dissiminated forms. Vein a...

Dehzaman iron deposit is located southwest of Bardaskan, Khorasan Razavi province, and northeast of Kashmar-Kerman Tectonic Zone. Geology of the study area consists of late-Neoprotrozoic-lower Cambrian metamorphsed volcano-sedimentary units, including slate- phyllite, sericite schist, recrystallized carbonate rocks, metarhyolite-metarhyodacite and granitic intrusions. Mineralization is hosted b...

The study area is located at the Soghanchi village (east of Miyandoab city, NW of Iran). The Oligocene age Soghanchi stock is intruded into Permian carbonate rocks during Pyrenean orogenic epoch. Petrographically, the main minerals of this intrusive are plagioclase, biotites, pyroxenes, olivines, hornblendes, and alkali-feldspars. The microscopic and geochemical assessments of intrusive, show g...

Khanlogh magnetite-apatite deposit is located in northwest of Neyshabour. This area is situated in Binaloud structural zone and east of Tertiary Quchan-Sabzevar magmatic arc. Geology of the area is dacitic volcanic rock intruded by Oligocene subvolcanic rocks with composition of quartz monzodiorite and granodiorite. Miocene sedimentary rocks trusted on them. The magmatism in the area shows char...
