... of the Esfordi apatite-magnetite deposit. We have been working in the Bafq mining district of central Iran for almost eight years, resulting in three graduate theses on the mineralization of the area. Based on our field experiences and mineralogical and geochemical data, we wish to comment on the conclusion...

.... Esfordi, a funnel filled with 50 Mt of magnetite-pyroxene-apatite, is being explored. Anomaly XX is a large magnetite prospect associated with uranothorianite mineralization at Duzakh Darreh. Narigan is a manganiferous jaspilite deposit situated in the former moat. Kushk is a subaqueous-hydrothermal...

...Daniel E. Harlov; Corey J. Meighan; Ian D. Kerr; Iain M. Samson Abstract The Kiruna-type Pea Ridge iron oxide-apatite (IOA) deposit is hosted by a sequence of 1.47 Ga rhyolite tuffs of the St. Francois Mountains, southeast Missouri, USA. It consists of a series of altered zones composed mainly...

... of the Kiruna type are the single biggest source of iron in Europe (e.g., Islamovic et al. 2015 ). These large, high-grade, apatite-iron oxide deposits occur worldwide and are generally associated with volcanic to subvolcanic rocks. Notable examples of Kiruna-type deposits include: (1) the Kiirunavaara (Kiruna...
