Description
Summary:ABSTRACT: In Mexico, very recently some iron-rich ore bodies were re-classified as belonging to the IOCG type deposits. Their disposition is roughly parallel to the Pacific Coast, but mimic the disposition of Chilean deposits into two distinctive Belts: (1) an older, Mesozoic belt located near the Pacific border, constituted by magnetite-rich bodies with Cu-Au accumulation; (2) a Tertiary belt, located inland Mexico, grossly parallel to the Mesozoic belt, made up by magnetite-haematite or haematite-rich deposits, with many similarities with the Kiruna (Sweden) or El Laco (Chile) types.
