It is indicated that the deposits of the same type have similar fluid inclusion geochemical features and physicochemical parameters though they belong to different minerogenetic series, while the compositions of inclusions are not conditioned by deposit types but closely related 关 键 词：south-central SECTOR of the Da Hinggan MOUNTAINS METALLIC ORE deposit fluid INCLUSION geochemistry
