[edit] Definition of mantle plume

I have restored my former definition of a mantle plume as an upwelling of abnormally (or anomalously) hot mantle, because some time ago, someone only identified by an IP has reverted it to an upwelling of molten rock. It is important to understand that this is wrong: in most parts of the plume, the rock is not molten, and even in those uppermost parts where it may be partially molten, it is far from being a 100% melt. I hope the new formulation helps to avoid in the future the misunderstanding that the earth's mantle is a magma ocean.--TomR 20:22, 14 June 2006 (UTC)

They do -- credit is given at the bottom of their page to Wikipedia.--Vsmith 00:28, 9 Sep 2004 (UTC) OK - I hit save and got an edit conflict - StoatBringer got there before me and did essentially the same editing :-) --Vsmith 00:34, 9 Sep 2004 (UTC)

D'oh, I didn't spot that (still a Wiki Newbie) StoatBringer
