Iwamori et al., (2015) Isotopic heterogeneity of oceanic, arc and continental basalts and its implications for mantle dynamics


By mining geochemical data of basalts from databases, such as PetDB, Iwamori and Nakamura created a large data set of isotopic values from Mid-ocean Ridge Basalts, Ocean Island Basalts and Continental Basalts. Independent Component Analysis was found to be applicable in capturing the overall structure of the data, including mantle geochemical end-members.
