Sar Cheshmeh
Kerman (southeast), Iran
PorphyriesCu-Mo (Au)
- Type
- Cu-Mo porphyry (Urumieh-Dokhtar magmatic arc)
The largest copper-molybdenum deposit in Iran, with reserves of 1,200 Mt at 0.7% Cu, 0.03% Mo and 0.06 g/t Au. The Miocene stock consists of diorite, granodiorite and quartz monzonite emplaced in several magmatic-hydrothermal pulses. Molybdenum concentrated early and copper later.

| 18.6 | sulfides (concentrates, without strong phyllic alteration) Value described as fairly uniform in the abstract, with no precise range in the sources consulted. Two samples cut by sericite veins are more radiogenic. | Shahabpour et Kramers 1987, Lead isotope data from the Sar-Cheshmeh porphyry copper depos… |
