I know, I know! I will not say (so that E.C may once again impress us with his brilliance <g>) but I will say that I very confident that NWI has the one we want! (coarse grained or fine grained pentladite)

Well yes the coarse stuff is supposed to be better but in my opinion they are saying that for totally fraudulent reasons. The people who are putting that opinion forward are the magmatic theorists or those who aver the deposits may have settled out of a crystal mush on cooling of the rock mass. This is false in the case of the Lynn Lake and Sudbury Orebodies as the ore post dates the Gabbro and the Norite respectively. Besides, there are many hydrothermal features of the deposit in both cases, despite the Frood's mixed disseminated nature in the quartz diorite host. You will find that these deposits are independent of the size of the gabbroic host and that therefore the possibility that the mafics are directly related any more than the felsics is moot. In fact you will find that the gneiss is the controlling factor as it is the only rock with enough nickel in it to act as a source. So if the gabbro was earlier than the ore and lacks nickel, what role could it play in deposition? Answer: none. If it were crystal settling by gravity then the orebody would have to be on the paleo bottom of the gabbro. That demands that the contemporary orientation of the gneiss to be underneath the gabbro! Well what was on top, if this was an intrusion, the volcanics? Bingo..! the magmatic differentiation theory suffers a credibility gap. Why would the ore be in a shear as well? The best you could do with that theory is have a late Gabbro sill, then a volcanic overlaying episode. That MAY have happened but I doubt it.

So let's travel now, shall we, to a happier land. The land the theorists first played in an 1955 and then again in 1961. The land Park and McDiarmid pointed to and the one the cu-zn children are so happy with. It is mysterious but correct world of hydrothermal ore. Visit the water-borne rumpus room and your problem orebodies fade away. The troubling low temperature thermal evidence and late dykes are no longer a problem. The ore is where it should be and you know what kids? You can find all the orebodies' friends, because you now know where they play.. along the volcano-sedimentary vent pile in gniess-gneiss nickel-packer land. Ask for father Hutchinson to show you the way to the vent playroom. Mr. Franklin will guide you when you get there. It is by the magic Redstone hill.
