The Oshvad skarn type deposit was formed during the intrusion of a felsic mass into the Permian and Triassic carbonate rocks and ion exchange occurred between the intrusion mass and these units. In order to determine the properties of the mineralizing fluid in this skarn, several fluid inclusions in quartz and calcite minerals of the mineralization...

Introduction Gold deposits formed during mountain-building processes in Phanerozoic terranes that formed in metamorphic environment have a great dispensation in the world (Goldfarb et al., 2001). They constitute an economically important type of gold mineralization called orogenic gold deposits (Groves et al., 2003). The Sanandaj-Sirjan zone is one...

The Se-Chahun Fe-P ore deposit is located in the Bafq mining district in the Central Iranian tectono-magmatic zone and contains REE and Th mineralization. The ore deposit consists of a magnetite-apatite massive ore that is significantly modified by late-stage metasomatic fluids that finally formed brecciated rocks within and at the margin of the or...

The Ti- Fe mineralization in Bafq 15 anomaly located 35 Km NW of Bafq city, and is a part of Poshte Badam Block in the Central Iran. Mineralization including magnetite, titanomagnetite, ilmenite, and minor pyrite which hosted by gabbro and pyroxenite intrusions syngeneticly. Based on the whole rock chemistry, FeOt, TiO2, CaO, Ni, Cr and V show a po...

Khormuj area is a major phosphate prospect area in the southwest of Iran. The area is located in the Khormuj anticline which is a part of Zagros folded geo-tectonic zone. Pabdeh Formation (Paleocene) is host of the sedimentary phosphate mineralization. Pabdeh Formation is often composed of marl, limestone, nodular cherty limestone containing glauco...

The Bondar Hanza porphyry Cu deposit, hosted by a granitoid stock, is located 120 km south of Kerman city in the elongated NW-SE trending Urumieh-Dokhtar magmatic arc (UDMA), Iran. The granitoid stock is a multiphase intrusive body, 2 km 2 in surface area, which comprises microdiorite-microquartz diorite and granite-grano-diorite. Petrological and...

The Oshvand Skarn Deposit is the largest copper, gold, and iron ore deposit in western Iran that is located in the Sanandaj Sirjan metamorphic-magmatic zone in the vicinity of Oshvand village, ten kilometers east of Nahavand city. This deposit is the first metal deposit introduced in Nahavand county and the first possible gold deposit of Hamadan pr...

The mafic-ultramafic intrusion in the Bafq anomaly Iron located 35 Km northwest of Bafq city, Central Iran. The 15 th anomaly intrusion intruded the Rizu sequence series, stratigraphically attributed to early Cambrian magmatism in the west of Posht-e-Badam block. The Rizu sequence series is composed of carbonate rocks of upper Neo-Proterozoic-early...

The Saghand Anomaly 5 is located in the Bafq-Saghand metallogenic province in the Central Iranian geostructural zone and contains Ti, REEs, Y, U, and Th mineralization.
