Title: Iron oxide-apatite deposits of the Bafq district, Central Iran: An overview from geology to mining [Magnetit-Apatit-Lagerstätten im Bafq-Distrikt, Zeirtral-lran -Ein kurzer geologisch-bergbaulicher Überblick]
The Bafq metal province in Central Iran hosts important Kiruna-type iron oxide-apatite deposits with a total resource of around 1.5 Gt iron ore (> 20 % Fe). The apatite content of the deposits varies between a relatively low-P magnetite ore (Choghart mine; 216 Mt @ 60 % Fe, 0.92 % P2O 5, 0.08 % S) to magnetite-apatite ore (Chador-Malu mine; 400 Mt @ 55 % Fe, 2.15 % P2O5, 0.19 % S) to apatite-(magnetite) ore (Esfordi mine; 17 Mt @ 14 % P2O5, 17.2 % Fe). All deposits are mined by the open-pit method. There is a distinctive alteration zoning in the ore systems from sodium alteration (albite) at deeper levels to potassic (K-feldspar) and then sericitic and actindrte alteration at higher levels which can be used as an exploration tool along with geophysical prospecting for new blind orebodies. Recent reinterpretation of the gee-tectonic setting of the magnetite-apatite deposits as of Andean-type, provides new exploration potential for the more than 1000 km long Kashmar-Kerman Tectonic Zone in Central Iran.
