V23C:
Understanding Monogenetic Volcanoes Posters

Submit an Abstract to this Session



Session ID#: 26007

Session Description:
Monogenetic volcanoes have been traditionally linked to a direct magma transfer from the mantle to the surface. However, recent detailed petrological and geochemical studies of some monogenetic eruptions suggest that magmas coming from depth in dikes were not able to go straight to the surface, but stalled at some intermediate depth developing a plumbing system where processes as magma mixing, crystal fractionation and/or crystal assimilation could occur.

Understanding the processes and magma plumbing systems that lead to monogenetic eruptions is fundamental for better interpreting the monitoring data of the unrest episodes in monogenetic volcanic fields and thus improve the eruption forecasting in these regions.

This is meant to be a multi-disciplinary session and we invite contributions that include field observations, geochemical, isotopic and petrological data, analogue models of dike propagation, monitoring data, and forecasting of eruptions.
