Abstract:
Supplemental material for publication: Winslow, H., Lynn, K.J., Downs, D.T., Lerner, A., Andersen, N., Nalesnik, A., Trusdell, F. “Utilizing crystal records to determine the underlying architecture and timescales of magmatic processes during the 2022 Mauna Loa eruption” (2025) Bulletin of Volcanology. The supplemental material consists of mineral chemistry (pyroxene, plagioclase, olivine) collected via scanning electron microscopy with energy˗dispersive spectroscopy (SEM˗EDS) at the U.S. Geological Survey’s Cascades Volcano Observatory in Vancouver, WA. Additional mineral (pyroxene, plagioclase, olivine) and glass chemistry were collected via electron probe microanalysis (EPMA) at the U.S. Geological Survey’s California Volcano Observatory in Moffett Field, CA. Melt inclusion chemistry and barometry using fourier transform infrared spectroscopy (FTIR) analyses were conducted at the U.S. Geological Survey’s Cascades Volcano Observatory. Fe-Mg diffusion chronometry was conducted on three orthopyroxene populations to estimate pre- and syn-eruptive timescales. Diffusion chronometry is paired with melt inclusion barometry datasets to provide a robust understanding of pre-eruptive processes in both time and space. All data is from the 2022 Mauna Loa, HI eruption.
