Diffusion chronometry and the timescales of magmatic processes
Volcanic eruptions can represent major societal hazards. Placing tighter bounds on the
timescales of magmatic processes that precede eruptions is, therefore, important for volcano …

[HTML][HTML] Igneous meteorites suggest Aluminium-26 heterogeneity in the early Solar Nebula
The short-lived radionuclide aluminium-26 (26Al) isotope is a major heat source for early

Plagioclase alteration and equilibration in ordinary chondrites: Metasomatism during thermal metamorphism
In ordinary chondrites (OCs), feldspar is present both in chondrules as a primary, igneous
phase, and as a secondary phase that results from crystallization of chondrule mesostasis …

Element and Sr isotope zoning in plagioclase in the dacites from the southwestern Okinawa Trough: Insights into magma mixing processes and time scales
The processes and time scales of magma mixing in shallow silicic magma chambers prior to
eruptions in the Okinawa Trough (OT) are still poorly understood. Here, we employed in situ …
