Abstract

Disseminated pyrrhotite-chalcopyrite. Host rocks are ophiolitic metabasites. Protoliths of the ore horizon were hydrothermally altered mafic rocks with silica and sulfides. Large-scale stockwork-alteration system. The predominant garnet-gedrite(-biotite-staurolite) assemblages of the ore horizon are products of polyphase metamorphism which was isochemical with respect to nonvolatile components.--Modified journal abstract.
