Abstract

Noranda-type massive sulphide deposits in some Archean greenstone belts of the Canadian shield occur in tholeiitic volcanic sequences, the tholeiitic rocks belong to basalt-ryholite bimodal suites with low AlO, high Na/K ratios, high iron contents, and well-defined iron enrichment trends.
