TL;DR: In this article, glass inclusions record the progressive transition of melt compositions dominated by an early calc-alkalic, high Mg andesitic stage to a younger tholeiitic stage over a time period of 11 Ma.
Journal ArticleDOI

TL;DR: In this article, the bubble number density (BND) of a crystal-free rhyolitic liquid with ≈ 6.6 wt. % H2O was measured at a pressure range from 250 MPa to 30-75 MPa in order to characterize effects of magma ascent rate and temperature on bubble nucleation kinetics.
Journal ArticleDOI
Classification of geochemical data based on multivariate statistical analyses: Complementary roles of cluster, principal component, and independent component analyses
Hikaru Iwamori,Kenta Yoshida,Hitomi Nakamura,Tatsu Kuwatani,Morihisa Hamada,Satoru Haraguchi,Kenta Ueki +6 more
TL;DR: In this paper, the authors show the relationship and complementary roles of k-means cluster analysis (KCA), principal component analysis (PCA), and independent component analysis(ICA) to capture the true data structure.
