Thermal evolution of Andean iron oxide-apatite (IOA) deposits as revealed by magnetite thermometry (Nature, 2021)Magnetite is the main constituent of iron oxide–apatite (IOA) deposits, which are a globally important source of Fe and other elements such as P and REE, critical for modern technologies. Geochemical studies of magnetite ...
