Hi Pete! You make a valid point. But it is not relevant here! ;) <gg> The general low gravity indicates a thicker crust (ie, the heavier material on which the lithosphere floats is further away), and therefore has cooler roots, meaning diamonds can survive in the stability field ... a deeper keel means cooler crust... -- This all pertains to the classical kimberlite model. It is a supported theory that this environment is needed for emplaced kimberlites to be diamondiferous (as the kimberlite volcanoes spew upward, through this field as far as 300km down, they collect the diamonds and carry them to surface ). -- Remember gravity is used as a qualitative tool, but it sure seems to be the one common denominator across N.American diamondiferous kimberlite fields, I'm learning. I am obviously a rookie here (forgive my inaccuracies), but Rick Boulay, prez. of Marum Resources, will be offering answers to this and much else I am sure, in a prepared "FAQ" document which he'll be passing along to me and I will be posting to the Marum thread, at least. Feel free to go to that SI thread and post any questions. -- Mr. Boulay monitors the thread and will offer any answers he feasibly can (by including them in the FAQ paper!).
