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

Iwamori,2015_200.png

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.
