The feature of oxygen isotope for magnetite from Abagong iron deposit reflects that the water in the fluid of mineralization resides in the initial magma, implying the magma genesis of mineralization. The similaritary features of REE and trace elements for coexisting apatite with magnetite in the Abagong, the Kiruna type and the Ninwu porphyrite iron deposit show their common genesis, indicating that Abagong iron deposit resulted from the intrusion of late ore magma due to the magma differentiation. The characteristic of sulfur isotope composition implies that the Abagong iron deposit resides in basaltic magma from mantle resource.
