Alteration-mineralization, and radiometric ages of the source pluton at the Sangan iron skarn deposit, northeastern Iran

Iron and Fe–Mn mineralisation in Iran: implications for Tethyan metallogeny

“…The Cenozoic Sangan iron deposit is one of the largest worldwide skarn deposits that is located in the east of CIZ (Khorasan Province) and divided into eastern, western and central ore bodies (Golmohammadi et al 2014). The ore is hosted by Cretaceous calcareous sediments and associated with felsic volcanic (rhyolite, trachyte, dacite, andesite) and Upper Eocene intrusive rocks (syenite to syenogranite porphyry) (Figure 15b).…”

“…The ore is hosted by Cretaceous calcareous sediments and associated with felsic volcanic (rhyolite, trachyte, dacite, andesite) and Upper Eocene intrusive rocks (syenite to syenogranite porphyry) (Figure 15b). Skarn mineralisation occurs at the contact of the 39.1 § 0.6 Ma to 38.3 § 0.5 Ma Upper Eocene syenite to syenogranite porphyry pluton with Cretaceous carbonate rocks (Mazaheri et al 1994;Karimpour 2004;Golmohammadi et al 2014). Although the Sangan syenite to syenogranite porphyry pluton show potassium to shoshonitic affinity, it has been proposed as subduction related pluton (Golmohammadi et al 2014) in the CIZ.…”

The main ore mineral is magnetite with minor hematite, pyrite, chalcopyrite and pyrrhotite.…”

Multi-Gaussian kriging: a practice to enhance delineation of mineralized zones by Concentration–Volume fractal model in Dardevey iron ore deposit, SE Iran

“…Skarn mineralization happens at the contact of the 39.1 ± 0.6 Ma to 38.3 ± 0.5 Ma Middle Eocene syenite to syenogranite porphyry pluton with Cretaceous carbonate rocks (Malekzadeh Shafaroudi et al, 2013;Golmohammadi et al, 2015). The Sangan complex consists of several ore bodies such as Dardevey, Baghak, A, A′, B, C and C North.…”

Mineralization, Mineralogy and Geochemistry of Saheb Fe-Cu Deposit of Saqqez (Kurdestan), NW Iran

“…There are many iron skarns in Iran. Some economically important well-known iron skarn deposits in Iran are as: Sangan [1] Gelali, Baba Ali, Khosro Abad and Shahrak [2] and Astamal [3] [4]. According to this, Saheb Fe-Cu skarn deposit is North-West Iran and coordinated 34˚46' to 35˚46' east longitude and 36˚16' to 36˚17' north latitude (part of Sanandaj-Sirjan zone is enclosed).…”
