UMD Planetary Volcanism Laboratory
Welcome to the University of Maryland Planetary Volcanism Laboratory!
We study volcanoes on Earth and beyond.
Research Questions
What are the sources and quantities of volatiles in the interiors of the terrestrial planets?
What factors control volcanic eruptive style on the Earth and other planetary bodies?
How fast does magma cool within the volcanic conduit? How fast does magma rise from source to surface?
Can we link petrologic markers of magma ascent to the seismic record at active volcanoes?
How did a mugearite form on Mars?
Research Keywords
Volatiles
Silicate melts
