"The greatest compliment that was ever paid me was when[some]one asked me what I thought, and attended to my answer."
Henry David Thoreau Andy Moore suggests: A useful source of information on recent publications is Gillian Foulger's mantle plume website www.mantleplumes.org
Gillian is trying to engage people to submit ~ 1000 word summaries of recent pro- or anti- plume papers to encourage debate.
This site is for those who are interested in the origin of "hot spots", or melting anomalies. For over 30 years the interrelated, but usually viewed as independent, plate tectonic and plume theories have been the two most important paradigms in the solid Earth sciences. The plume theory, invoked to explain “hot spot” or “anomalous” volcanism, is currently under vigorous debate. The primary objective of www.mantleplumes.org is to encourage this discussion by making a broad suite of relevant information easily available to students, specialists in all branches of the Earth sciences, and lay people.
