Dodehak granitoid stock with tonalite to granodiorite compos ition is exposed south of Dodehak vi llage, north of Ab-e-Gann (Mahalat) in Urumieh-Dorhtar volcanic belt of Iran. Based on petrography and point analysis (EPMA). plagioclase crystals show nonnal zoning with graph ic tex.ture is present. Samples from SE of the intrus ion are different and myrmekite texture is present in the rocks...

The Miocene Qohrud granitoid intrusion consists of granite, granodiorite and tonalite and is located in the Urmia-Dokhtar magmatic belt. Intrusion of magmatic rocks into the various sedimentary rocks including shale, sandstone, limestone and marl, with Jurassic to Eocene age, has caused contact metamorphism of the surrounded rocks. Varity of hornfelses and skarns are formed in this regards. Hyd...

In southeast of Bardsir (Kerman Province), there is a volcanic complex belongs to Uromieh-Dokhtar volcanic belt.This complex mainly contains basaltic-andesite and basalt lava flows with the Eocene age, alternative with pyroclastic rocks. Petrographic evidences include zoning, sieve texture and rounded crystal in plagioclase and pyroxene phenocrysts disequilibrium conditions between crystals and...

Kalchoyeh copper deposit is located about 110 km east of Isfahan, in Central Iran, Urumieh- Bazman volcanoplutonic belt. Host rocks of this deposit are Eocene volcanic rocks and tuffs which are pyroxene andesitic lava and sandy and lithic tuffs. Sandy tuffs are the main host rocks of the deposit. Ore mineralization is taken place as veins and veinlets and quartz is the main gangue mineral. Hypo...

Sarvian intrusion is located in northeast of Delijan in the Orumieh-Dokhtar magmatic belt. Sarvian pluton consists of acidic and intermediate units and is composed of granite, granodiorite, tonalite and quartz-diorite. Main minerals of the intrusion are plagioclase, amphibole, biotite, quartz and K-feldspar. In this research, based on the EPMA analyses, thermobarometry of the rocks investigated...
