Description: The term monogenetic volcanism defines small volume magmatic systems whose surface expression can be isolated or forming volcanic fields, as a consequence of strong structural control (faults, fractures and dikes) that facilitates magmatic ascent to the surface. This volcanism can start without important precursor signals that would allow us to be prepared for the rise of a new volcano, remarking the importance of the study of this type of volcanism in the rural and urban areas of Chile. The genesis of these small eruptive centers has been of great interest in the last decade, as they are considered “windows” to the magma generation processes from the upper mantle. Furthermore, the eruptive style can easily change from effusive to explosive in short periods of time, allowing the analysis of internal and external parameters that controls its evolution.

We invite authors to submit abstracts about the genesis and evolution of these magmatic systems, including the different factors and processes involved in the emplacement and formation of these systems in different settings. Works that allow the understanding of monogenetic volcanism on Geochemistry, Petrology, Physical Volcanology, Geophysics, Modeling, Geoheritage and Volcanic Hazards topics, among others, are welcome in this session.
