摘要

•IOCG mineralization in the south occurred at 2.72–2.68 Ga and 1.88 Ga.•IOCG mineralization in the north occurred 2.60–2.45 Ga.•Nickel-PGE deposits are hosted by 2.76 Ga mafic–ultramafic bodies.•Polymetallic Cu-Au deposits occurred 1.88 Ga synchronous with A-type granites.•Hypogene BIF-Fe mineralization is Proterozoic.
