Compositional Data Analysis (CoDA) of Clinopyroxene From Abyssal Peridotites
Geochemistry, Geophysics, Geosystems, 2022 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 ...

Large Silicic Eruptions, Episodic Recharge, and the Transcrustal Magmatic System
Geochemistry, Geophysics, Geosystems, 2020 Large silicic eruptions result from rapid evacuation of large, upper crustal reservoirs of silicic magmas. These silicic magmas are thought to be replenished by melt extracted from underlying crystal‐rich source mushes, but the timescales and mechanisms ...

Porosity evolution of mafic crystal mush during reactive flow
Nature Communications, 2023 The emergence of the “mush paradigm” has raised several questions for conventional models of magma storage and extraction: how are melts extracted to form eruptible liquid-rich domains?
