How much Zinc produced at Sudbury? So there are different areas with different minerals. Amazing. Not much nickel or gold in Kidd Creek either. Your nemesis. The Vermillion Mine. Yes it kinda destroys the neat magmatic only theories of Sudbury. What is this cu-zn VMS deposit doing in the Whitewater seds in the middle of the basin? Insignificant? Or the thin edge of the VMS wedge. What I mean is that this flow/intrusion has a rather obvious bottom contact with the gneiss. I presume you think that that is it paleo bottom as a sill, n'est-ce pas? I think it is the sea bed trough that it flowed into from a feeder dyke. The only difference here is that I aver that there was nothing on top of it but 5,000 feet of seawater. You seem to think that there was 40,000 feet of sediment that has subsequently eroded. But If that were true I don't think you would see these late volcanics and sediments so nearby. At what age do you presume it to be exposed and the volcanics subsequently layed down nearby? If the volcanics were earlier how do they exist at the same erosional level? re papers: I am still looking for the best one done in 1948. You could always try authors. Start with Fairbairn and Hutchinson. Study the Redstone Deposit. EC<:-}

talk about getting off the topic but there has been zinc production in the Sudbury Basin, not associated with the the Ni ores, but with the younger overlying felsic volcanics. There are Ni deposits associated with flows - komatiites in composition, they do show flow structure, someone mentioned the Timmins NI deposit -Redstone?? I believe this to be an example as are the famous ones in Kambalda, Australia. But most geologists would agree with a magmatic theory for Sudbury and Voiseys. Its too early to speculate on NWI unless some of the writers have seen the core?? geo in Denver
