"Contrary to received opinion a theory... is not normally rejected merely because it is falsified... falsifications and discovery of counter-examples and exceptions merely spur one on to greater ingenuity... in modifying the theory to accommodate the nuisance...”

Check out the Wikipedia Talk:Mantle plume controversy page and add your three ha'pence worth–or 10¢ if you work in bucks.–Gillian R. Foulger
Dear WM, A new gravity map shows thousands more of seamounts, mostly not in linear chains, as summarized in this news article. The great majority of seamounts are scattered across the oceans in independent groups and individual volcanoes. They are not part of linear volcanic chains, and we should note that magmas of most seamount volcanoes appear to be similar and must form the same way. This fact does not support the wildly generalized models in which intraplate volcanoes are created by narrow, deep mantle plumes. Instead, we must develop models that link lithospheric structures to linear volcanic chains where such exist, and also allow most volcanoes to form as individual features, all in a common origin from the upper mantle.–Greg McHone
Dear WM, in the recent paper by Courtillot & Fluteau, the 59th plume type is defined–the "killer plume".–Michele Lustrino
