Global Fe–O isotope correlation reveals magmatic origin of Kiruna-type apatite-iron-oxide ores

The origin of giant Kiruna-type iron ores has been debated for nearly 100 years. This study employs extensive stable isotope data from Kiruna-type ores worldwide and magmatic and hydrothermal reference materials to show that iconic Kiruna-type ores originate primarily from ortho-magmatic processes.
