    Fast crystallization altered microlite-melt chemistry in a Hunga eruption bomb

    What the study found Fast crystallization in an intact bomb from the 2022 Hunga eruption produced increasing microlite content toward the bomb interior and stronger chemical and textural disequilibrium in clinopyroxene and plagioclase microlites. The authors report that these far-from-equilibrium processes also created melt compositional trends that could resemble pre-eruptive fractional crystallization. Why the authors…
