Shatsky Rise consists of thick (∼30km maximum) basaltic crust with various geochemical compositions. Geochemistry data indicate that four magma types exist on the plateau; namely normal, low-Ti, high-Nb, and U1349 types. The normal type is the most a...

Baksi (2012) claims that a number of radiometric ages presented in Barry et al. (2010) are statistically invalid and that many of the samples were altered, thus not able to date the eruptions, and that there is no compelling evidence for a limited du...
