Compositional Data Analysis (CoDA) of Clinopyroxene From Abyssal Peridotites

Compositional Data Analysis (CoDA) of Clinopyroxene From Abyssal Peridotites

Abstract We analyze a large database of abyssal peridotite clinopyroxene compositions using log‐ratio transformation, principal component analysis (PCA) and k‐means clustering, to better understand clinopyroxene compositional systematics in abyssal peridotites. We combine this analysis with open‐sys...
