One hypothesis invokes direct crystallization immiscible Fe-rich melt that separated from a parent silicate magma, while the deposition Fe-oxides hydrothermal fluids either or crustal Here, we present new model based on O stable isotopes trace major element geochemistry data ∼350 Mt Los Colorados IOA deposit in Chilean belt merges these divergent into single sequence events explains all characteristic features curious deposits. We propose concentration takes place preferred wetting magnetite, followed buoyant segregation early-formed magnetite-bubble pairs, which become rising suspension massive regional-scale transcurrent faults. Our demonstrate unambiguous origin, consistent with namesake analogue Kiruna district, Sweden. Further, our observed coexisting purely hydrothermal-magmatic allows genetic connection between oxide–copper–gold deposits, contributing global understanding valuable exploration efforts.
