  • Geochemistry and origin of amphibolite and magnetite .

    It is suggested that the magnetite ore may have been derived by metamorphism of iron-rich sediment originally deposited in an environment of pelite-carbonate sedimentation. The chemical similarity of magnetite-bearing amphibolites from the Yangyang iron mine in Korea to mixtures of pelite and limestone or dolomite is consistently indicated by all the available chemical data.
