The Karmozd coal mine in Mazandaran Province (Iran) is one of the largest and oldest active coal mines in Central Alborze Coal Basin. A complete geochemistry and mineralogy characterization of Karnozd coal has been conducted in summer, 2005 by sampling of coal, coal tailing and country rock coal Basin.The coal layers (Lias) is embedded in the middle of Karmozd litostratigraphic unit. It is comp...

The Kahrizbeyg pluton is located northwest of Iran in Central Iran zone. It is emplaced into the Cretaceous limestones in which contact metamorphism has happened. Meanwhile, rock fragments of this pluton are found in conglomerate units of Early Oligocene Lower Red Formation. Therefore, the relative age of pluton is between Cretaceous and Oligocene. The Kahrizbeyg pluton consists of granite and ...

Gazu prospect area is located about 65Km southeast of Tabas in the southern part of Shotori range. Sub­­-volcanic intermediate intrusive rocks (Upper Cretaceous?), monzonitic to dioritic in composition, intruded into carbonate rocks of Shotori Formation (Triassic) which are the main source for copper mineralization in Gazu district. Alteration zones associated within the intrusive are: Quartz- ...

Pillow lavas are one of the important rock units of Nain ophiolite. Rock forming minerals of Nain ophiolite pillow lavas are chloritized olivine, plagioclase, clinopyroxene (augite), Cr-spinel, magnetite, amphibole, chlorite, pumpellyite, epidote, prehnite and calcite. Whole rock geochemical analyses and composition of clinopyroxenes and chromian spinels of these rocks indicate that they are si...
