"Let us devote ourselves
to pursuit of the ultimate truth about nature by
studying what we can find around us. Of course we
must respect and value existing theories, but it
is important not to place too much confidence in
them. We should be free from authority and convention
and modest before Mother Nature.
We should investigate books and
articles written by famed scholars. The most critical
thing, however, is to observe nature with unbiased
eyes, experiment with our own hands, honor fresh
ideas gained from natural materials, and nurture
them in a lively environment."
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
