Immiscible hydrous Fe–Ca–P melt and the origin of iron oxide-apatite
Introduction. The origin of orebodies composed of low-Ti iron oxide minerals (magnetite and/or hematite) and apatite in (sub)volcanic rocks is controversial 1 – 12.These rocks, essentially free of silicates and sufficiently enriched in Fe to be recoverable, have been classified as Kiruna-type or iron oxide-apatite (IOA) deposits 1 – 3.Their enrichment in Fe and P has …

Geochemical and spectroscopic investigation of apatite in the
Apatite-rich carbonatite and glimmerite contain up to 30 vol% apatite, and apatite veins are essentially monomineralic (~80 vol% apatite; O'Brien et al., 2015). The Siilinjärvi mine produces about 11 Mt/yr, with ore reserves of 234 Mt at an average grade of 4 wt% P 2 O 5 (data for January 2014; O'Brien et al., 2015).
