Marion CARPENTIER

Marion was a ClerVolc postdoctoral fellow from 2012 to 2014. She worked with Olgeir Sigmarsson to understand the causes of major fissure eruptions and their potential influence on central volcanoes in Iceland. The focus was on Katla and Grímsvötn volcanoes and their associated large fissure eruptions, respectively Eldgjá (AD 934-37) and Laki (AD 1783-84). Trace element concentrations, Sr-Nd-Pb isotope compositions, and U-series radioactive disequilibria were measured on volcanic products from known historical and pre-historical eruptions. Possible links between variation of the magma source and melting parameters and volume of emitted magma were investigated, as well as the effect of very large basaltic fissure eruptions on the central volcano behaviour.
