February 20, 2017: "Volatiles and Volcanic Vigor"

Talk given by Prof. Dr. Terry Plank as a "The Geological Society of America (GSA) James B. Thompson, Jr. Distinguished International Lecture“ and a "Marie-Tharp Lecture Series for Ocean Research"

 

11:00 h

Lecture Hall - GEOMAR, Eastshore, Wischhofstraße 1-3, 24148 Kiel

 

Abstract:

What causes some eruptions to be more explosive than others? Is it the total driving gas fuel, or how fast the gas escapes? This talk examines both the volatile content and the speed of magma ascent immediately prior to eruption. Chemical zonation preserved inside glass pockets and crystals provides some of the fastest clocks in geology. These timescales of chemical diffusion operate over minutes to hours in the run-up to eruption.
