Pantelleritic magmas are low-viscosity peralkaline rhyolites which exhibit large differences in eruptive style (explosive to effusive). The processes that promote fragmentation and explosive…
Mafic explosive volcanism at Llaima Volcano: 3D x-ray microtomography reconstruction of pyroclasts to constrain shallow conduit processes

Mafic volcanic activity is dominated by effusive to mildly explosive eruptions. Plinian and ignimbrite-forming mafic eruptions, while rare, are also possible; however, the conditions that promote…
Magma Pressure-Temperature-Time Paths During Mafic Explosive Eruptions

We have constrained syneruptive pressure-temperature-time (P-T-t) paths of mafic magmas using a combination of short-timescale cooling and decompression chronometers. Recent work has shown that the…

Microlite crystallization in erupting basalt can occur in the conduit, in flight, or in situ after deposition. Distinguishing the products of primary versus secondary (post-fragmentation)…
Porosity-permeability relationships in crystal-rich basalts from Plinian eruptions

Magma permeability allows release of exsolved and pressurized volatiles during magma ascent, potentially modulating explosive volcanic eruptions. While porosity-permeability relationships in the…
Highly explosive basaltic eruptions driven by CO2 exsolution
- GeologyNature communications

Evidence is presented for an exsolved CO 2 phase ~15 km beneath Sunset Crater that was the critical driver of rapid magma ascent leading to the explosive eruption of the most explosive basaltic scoria cone eruption yet documented.
