New research supports volcanic origin of Kiruna-type iron ores

The origin of giant apatite-iron oxide ores of the so-called ‘Kiruna-type’ has been the topic of a long standing debate that has lasted for over 100 years. In a new article, published in Nature Communications, a team of scientists presents new and unambiguous data in favour of a magmatic origin for these important iron ores. The study was led by researchers from Uppsala University in Sweden.
