Magmatism at Incipient Rift, Galapagos Triple Junction: Tapping the Off-Axis East Pacific Rise Melting Regime
Journal Article Geophysical Research Letters · October 28, 2025 Incipient Rift (IR) is the latest in a sequence of short-lived rifts that form ridge-ridge-ridge triple junctions with the East Pacific Rise (EPR) in the Galapagos triple junction region. IR extends ∼65 km southeastward from its intersection with the EPR a ... Full text CiteEvidence of South American lithosphere mantle beneath the Chile mid-ocean ridge
Journal Article Earth and Planetary Science Letters · October 15, 2023 Numerous geochemical studies on mid-ocean ridge basalts have established the presence of both compositional and lithological heterogeneities in the upper mantle. These studies have successfully constrained the composition and age of the chemical heterogene ...

Journal Article American Mineralogist · May 1, 2023 Trace concentrations of H2O in olivine strongly affect diverse mantle and magmatic processes. H2O in olivine has been difficult to accurately quantify due to challenges in sample preparation and measurement, as well as significant uncertainties in standard ... Full text CiteRecent Grants
