Feb 27, 2019 (Sheree Hinz) - Martite is an alternate term for hematite that is pseudomorphous after magnetite and, rarely, after pyrite. The martite occurrence may best be described as a skarn deposit. It is composed of dense, fine-grained rocks comprising garnet, pyroxene, amphibole epidote, magnetite, pyrite, pyrrhotite and carbonate, with minor chalcopyrite.
