<<<Rates of erosion and deposition generally have been suggested in Canada of as much as 1 mile per 10 my. Even if such rates are off by a factor of 4 on the craton which has been subjected to the deepest ice scouring, can you imagine how much kimberlite and surface rock have been eroded over the suggested age of this deposit?>>> If this is true, there must be hundreds of thousands of diamonds scattered all over the tundra to the South East of Snap Lake. Perhaps the volcanic eruptions of this time buried the deposits in hundreds of meters of ash and volcanic debris, protecting Snap from this erosion for many, many thousands of years. If all events were erosional, we would not be uncovering any dinosaur bones, and the mountains in B.C. and elsewhere would not exist. Cratons are believed to be more stable,...but who was there to know for sure. <<<Can anyone confirm whether there were modest ratio's of G10's vs G9's plotted for Snap Lake? If G9's are significantly more numerous, then I believe this suggests that there was a higher rate of reabsorbtion which may be suggestive of deeper solidification, heat retention hence probably a root zone.>>> My discussion with Winspear people suggested the presence of G11's and G12's. How do these fit into your equations. They felt they indicated a superior source of diamonds. Who am I to argue. Much is still to be learned. To think that the chemical trends discovered in Southern Africa can be used to explore the volcanic events in cratons in the NWT, Alberta, Ontario and Brazil etc., is rather dogmatic,...don't you think. My experience shows few sites display exactly the same characteristics. Of course, prudence suggests we look at the past to describe the present. Sometimes true, sometimes not (gggggggggggggggg).
