About this Research Topic
Monogenetic volcanism produces small volcanic edifices built up from a single short eruption (few hours to few years). Therefore, their complexity and associated hazards are sometimes underestimated. Magmas feeding monogenetic eruptions can “escape” from the crustal magma reservoir of a polygenetic volcano to create an isolated scoria cone, dome, or maar in the vicinity of the main eruptive center. Alternatively, they can originate and rise rapidly from deep sources in the mantle to create monogenetic fields of distributed edifices reflecting various eruptive styles at short distances from the others. These variations in eruptive dynamics also exist at the scale of the volcanic edifice itself and multi-phase eruptions can result in the formation of a complex layer cake -style edifice alternating a variety of volcanic materials. These small volume volcanoes exist in all geodynamical contexts all around the globe and thus generate interest from the broad volcanology community.
The small volume of magma created and transferred from depth to the surface to build a monogenetic volcano as well as the relative brevity of an eruption, make it a challenging subject to study and to monitor. Many questions remain unanswered concerning the processes associated with magma generation, transport modalities from source to surface, and chemical and physical interactions between magma, groundwater, pre-existing structures, and geological units in the crust. When thinking about the factors causing the variety of eruptive styles in monogenetic fields, we still need to define the respective contribution of (1) magma composition, including contamination along the way up and (2) shallow interaction between magma, bedrock, and groundwater. New advances in geophysics help imaging volcanoes increasingly deeper with high resolution (e.g. 3D electric resistivity tomography with Fullwaver systems) and to better interpret the nature of underground rocks e.g. with induced polarization, that allows detecting altered volcanic rocks associated with volcanic hydrothermal activity. Geophysics is one example but new technologies and techniques developed in all the disciplines will help understanding processes associated with monogenetic volcanism and by extension, polygenetic volcanism.
We welcome original studies, reviews, and methods articles on all types of monogenetic volcanism (volcanic fields, adventive cones associated with stratovolcanoes and with rift zones), using field and laboratory methods, analog experiments, numerical simulations, and remote sensing. We welcome contributions that focus on multiscale geophysical imaging and high resolution near surface geophysics, shedding light on interactions between magma, bedrock, and groundwater. Likewise, we aim at collecting articles looking at geochemical and petrological data to provide insights on magma generation and transfer from source to surface, that are specific to monogenetic volcanism. Studies on the geomorphology, physical geology, and statistical processing (e.g. machine learning) at scales from volcanic field to minerals would also be of great interest. We strongly appreciate interdisciplinary studies that emphasize links between science and society around monogenetic volcanic fields, related to either geohazard or to cultural and geoheritage thematics.
