GMPV Campfires – Call for Speakers The EGU Geochemistry, Mineralogy, Petrology and Volcanology ECS committee are currently looking for early career scientists to present at and attend our monthly online talk series (EGU Campfires). The EGU Campfires are a free one-hour online seminar consisting of three to four 10-12-minute talks. These quick-fire presentations give you an opportunit ...[Read More]

Elemental etymology – what’s in a name?

Like many scientists in the GMPV sphere, I work a lot with geochemistry – using chemical elements and their differing behaviours, abundances or isotopes as tools to understand Earth processes. While staring at the periodic table, something that’s always niggled at me is where the names of these come from: why is the stuff we breath called oxygen and the sand on the beach made of silicon? Even more ...[Read More]

Thermobarometry: a bit of background Being able to understand the eruptive style of a volcano, how the eruptive behavior can evolve over time and managing to better interpret the signals that a volcanic system gives us before an eruption are of fundamental importance for mitigating the risk associated with eruptive activities. In this context, it is extremely important to understand trans-crustal ...[Read More]

For geochronologists it is all about precision and accuracy. For petrochronologists it is more about precise positioning of those ages to trace back the evolution of a rock. For many, it is not just about getting a crystallisation or metamorphic age, it is about knowing when and at what conditions a given rock experienced certain petrogenetic processes. As we progressed from geochronology to petro ...[Read More]
