Correlated strontium, carbon and oxygen isotopes in carbonate gangue at the Nanisivik zinc-lead deposits, northern Baffin Island, N.W.T. Canada

We have analysed the Sr and C isotopic composition of samples of white sparry dolomite (WSD) interbanded with sulfides, vug-filling dolomite and calcite, and host dolostones associated with lead-zinc mineralization at Nanisivik, N.W.T. Canada. Ore stage WSD and late stage carbonates are considerably more radiogenic in 87Sr and depleted in 13C and 180 than dolomite of the host rocks. Within single WSD bands there is a negative linear correlation …
