OFF Topic I agree with 1king and Naldrett about Voisey's Bay being magmatic. The esteemed Mr. Charters has apparently misidentified the Tasiuyak paragneiss beneath the VB massive sulfides. I (like many worked the VB deposits) believe the Tasiuyak is very important as the sulfure source for Voisey's Bay. New U-Pb isotope interpretations (D. Scott, Precambrian Research, vol. 91, 1998, p.91-107) suggest the Tasiuyak rocks were trench sediments which underplated the over-riding Nain Plate. (For those non-geos on the board--paragneiss is metamorphosed rock from initial sedimentary rock; orthogneiss is from igneous rock.) Such a re-interpretation of the Tasiuyak as trench sediments (+1300 kms in strike length and remarkable homogeneous and probably analogous to today's Sunda Trench sediments) rather than Rae (formerly called Churchill) sediments may be very important to Labrador exploration for VB-style mineralization. On Wednesday at the Annual SME-SEG Meeting I presented a new tectonic model which utilizes Scott's isotope work. It may explain why Harp Lake (South Voisey) and Okak Bay are uneconomic (Sorry, Teck and now(?) Falco). It would also explain why the 1.3-Ga age giant troctolites in Greenland are barren too. Finally is nicely explains the eastern plunge of almost all Voisey's Bay orebodies. Ore Geology Review (Elsevier) wants me to publish soon. Maybe the esteemed Mr. Charters can "critique" our magmatic models in the scientific journals too. (Mr. Charters may be pleased to know, that the Archean prospectors who resampled Ryan's gossan (in 1994) thought it was related to VMS-copper mineralization at first too.) Best Regards, Terry J.

You drilled it. But your eyes saw what they wanted to see. Your mind is brainwashed by the necessity of regurgitating to professors the necessary dogma. Remember replacement ores? How long did people worship at that cathedral of nonsense before they excommunicated it? Was it a 100 years where students wrote of replacement and people wondered practically how it can happen? And where did the materials go that the ores replaced? Un Huh.. so it's science?

Would you like to remove the quartz clasts from you gneiss? Ok. I will do that if you like.

I think you were in ophiolitic terrane.
