The study area is located in Hamedan Province adjacent to Alvand plutonic body in the Sanandaj-Sirjan zone. Various contact and regional metamorphic rocks, from low to high grade exist in contact of Alvand plutonic body including schists, hornfelses and migmatites. Kyanite-bearing rocks volumetrically are not widespread but occur as various outcrops (in migmatite, hornfels and quartz-kyanite ve...

The Maherabad gold-rich porphyry copper prospect area is located in the eastern part of Lut block, east of Iran. This is the first porphyry Cu-Au prospecting area which is discovered in eastern Iran. Fifteen mineralization-related intrusive rocks range (Middle Eocene 39 Ma) in composition from diorite to monzonite have been distinguished. Monzonitic porphyries had major role in Cu-Au mineraliza...

The studied volcanic rocks are located in south of Sarab at the northern part of the Bozghoush mountaion. The rocks are megaporphyry andesite flows and trachy andesite basalt lavas associated with tuff. In the northern part of the study area these rocks are covered with younger sediments of Quarternary age. These rocks are containing phenocrysts of analcime, olivine, pyroxene and plagioclase. T...

Kahang porphyry copper deposit is located in Isfahan Province, in the middle of Urmia-Dokhtar Magmatic Belt. Based on field investigations and petrography of thin sections and core samples, igneous rocks in eastern part of the deposit are divided into three types of host-rocks, source and mineralizing rocks, and post-mineralizing barren dikes. Quartzdiorite has formed more than 70 percent of th...

Deylaman area lies on Paleogene volcanic rocks in Western Alborz near the border between Central and Western Alborz structural zones. The succession of Paleogene rocks in the area is comprised of three separate phases each of which representing one stage of volcanic events. The main purpose of this paper is to study the lithologic sequence and geochemical characteristics of phase two volcanic r...

The major syenitic bodies of Iran are spread on northwestern part, East Azerbaijan Province, which belong to late Eocene, early Oligocene magmatisem. Abbasabbad–Bashkand pluton is one of these intrusions, which is located as some minor and autonomous bodies in western side of the main Bozghush nepheline syenite pluton. Porphyritic, microgranular and porphyritic microgranular are common textures...

about 50 Km northwest of Bardeskan, Eocene volcanic and volcano sedimentary rocks of magmatic belt of north central Iran structural zone are host of Abri copper deposit. Volcanic rocks dominantly have andesitic, basalt and andesitic basalt composition, and manifested such as submarine lava flows, brecciated lavas in the present of water (agglomerate), or ash and fragmented volcanic rocks (tuffi...
