Marc-Antoine Longpré, Principal Investigator
My research interests lie where volcanology, igneous petrology and mineralogy mingle and mix. In the field, I examine and sample tephra and lava sequences to reconstruct the eruptive histories of volcanoes. In the lab, I analyze the chemical composition of volcanic rocks and their constituents (volcanic glass, minerals and their inclusions) to decipher the dynamics and timescales of magma reservoir and eruption processes, such as magma crystallization, mixing and degassing.
More specifically, I’m particularly interested in the following topics:
• Crystal records of magmatic processes and timescales
• Melt inclusion records of magma degassing
• Petrologic monitoring of volcanic eruptions
• Deep volatile fluxes and mantle geodynamics
• Environmental impacts of volcanic eruptions

Lisa Hlinka, PhD Student
Lisa gathers information locked in olivine and clinopyroxene crystals to estimate the timescales of eruption initiation and lava emplacement during Columbia River flood basalt volcanism.

John Zayac, PhD Student
John uses field work and rock compositions to reconstruct the eruptive history and magmatic evolution of Monte Galán caldera and Momotombo volcano in Nicaragua. At Cosigüina volcano, he utilizes the chemical composition of melt inclusions and textures of scoria and pumice to infer the mechanisms that trigger eruptions.

Shuo Ding, Postdoctoral Fellow
(now Associate Research Scientist at Lamont-Doherty Earth Observatory)
Echo utilizes apatite crystals, melt inclusions and modeling to constrain factors, such as redox conditions and magma recharge, that favored the build-up of sulfur in the magma reservoir that yielded the 1257 CE eruption at Mount Samalas, Indonesia.
