The Shaytor apatite-rich iron deposit is located in the Kashmar-Kermantectonic zone in the central of the Iranian plat, which is an importantpolymetallic belt in Iran. The ore bodies are interbedded with the upperinferacaamberian calc-alkaline igneous rocks that show well-preservedporphyritic and volcaniclastic textures. The iron ores have massive,disseminated, and brecciated structures. Magnetite from the Shaytor deposit islow in Ti TiO2 = up to 0.70 wt.% and different ore types show similar rare earth element REEand trace element-normalized patterns with weak-to-moderate enrichment in lightREE and negative Eu anomalies, indicating a common source and genesis.The similar REE patterns for the magnetite and volcanic basaltic host rockssuggest their close genetic linkage and support a magmatic origin for thedeposit. The Shaytor deposit shows thetypical characteristics of Kiruna-type deposits with regard to the mineralassemblages, ore texture and structure, and the apatite and magnetitegeochemistry. We propose that the Kiruna-type Shaytor apatite-rich iron depositwas derived from Fe-P-rich melt through liquid immiscibility and the activity ofhydrothermal fluids.
