Reconciling petrologic magma ascent speedometers for the June 12th, 1991 eruption of Mt. Pinatubo, Philippines

M Harris, B Hosseini, M Myers, L Bouley - Volcanica, 2024 - jvolcanica.org
We investigate whether decompression rates derived from three often-disparate petrologic
techniques (microlites, bubbles, and melt embayments) can be reconciled or integrated for a …

[HTML][HTML] Melt embayments record multi-stage magma decompression histories

B Hosseini, M Myers - Journal of Volcanology and Geothermal Research, 2024 - Elsevier
Over the last decade, the melt embayment has proven its merit as a robust petrological tool
capable of recording magma decompression rates for explosive eruptions. However, the …

Deciphering clues regarding magma composition encoded in quartz‐hosted embayments and melt inclusions through direct numerical simulations

Z Wei, AC Ruefer, AS Pamukcu… - Journal of Geophysical …, 2024 - Wiley Online Library
Crystal‐hosted melt embayments and melt inclusions partially record magmatic processes at
depth, but it is not always obvious how to interpret this record. One impediment is our …

Rehydrated glass embayments record the cooling of a Yellowstone ignimbrite
