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 replacements, veins and stockworks. Chemical Th-U-total Pb dating of high-Th monazite in apatite by electron microprobe analysis yields an isochron age of 515 ±21 Ma (initial PbO intercept = 68 ppm), or 529 ±21 (forced initial PbO = 0), which is contemporaneous with the emplacement of the volcano-plutonic host rocks of the magnetite-apatite mineralization, as well as with widespread sedimentation of Late Proterozoic to Cambrian evaporitic rocks in Central Iran. The monazite age and the mineralogical and geochemical data suggest that the magnetite-apatite deposits are likely related to large-scale brine circulation induced by Cambrian felsic magmatism.
