...F. M. Torab; B. Lehmann Abstract The Bafq mining district is in the Early Cambrian Kashmar-Kerman volcano-plutonic arc in Central Iran and hosts important ‘Kiruna-type’ magnetite-apatite deposits. The hydrothermal magnetite-apatite mineralization occurs mostly as massive orebodies, metasomatic...

... southeast of Tehran and 35 km northeast of Bafq. It is one of the most P rich of more than 34 major magnetite-apatite occurrences in the Bafq district, which contains an overall resource of 750 Mt of high-grade Fe ore ( National Iranian Steel Corporation, 1979 ). Production from the Esfordi open pit mine...

.... As temperature declines and the fluid chemistry evolves, localized REE leaching takes place within fluorapatite and leads to secondary allanite and monazite crystallization. Such processes have been observed experimentally and inferred in IOA deposits ( e.g ., Kiruna district in Sweden, Bafq district in Iran...
