Monogenetic volcanoes: physical volcanology, eruption dynamics, and eruptive styles

Conveners:

This session that will provide insights into eruptive mechanisms, dynamics, and eruptive styles of monogenetic volcanoes such as scoria cones, lava domes, maars, tuff rings, tuff cones, and other small volcanoes. Contributions rely on field studies of the rocks and deposits, laboratory analyses of the products, experiments, and/or models. The session will focus on:

• The factors that control eruptive styles, and the interplay between internal (e.g., magma composition, magma volume, gas content, magma rheology, etc.) and external (substrate characteristics, hydrogeology, etc.) parameters.
• Why scoria cones are more abundant than maar craters even though there are aquifers in almost all volcanic fields.
• How to link eruptive styles and fragmentation mechanisms with specific observable or measurable characteristics of the deposits.

All presentations on these and similar topics are part of this session.

Morphology, structure, and geophysical modeling of monogenetic volcanoes

Conveners:

This session focuses on the external morphology and morphometry (e.g., size, shape, volume), architecture, and internal structure (e.g., diatreme, feeder dyke, plumbing system) of monogenetic volcanoes.

The session includes contributions on reconstructing eruption history and understanding interactions with the substrate, focusing on the construction, evolution, and/or degradation of monogenetic volcanoes. Field studies, geophysical methods, numerical and analog modeling of volcanic processes, remote sensing, and GIS analyses conform to this session.

Geochronology, tectonic, and spatial distribution in monogenetic systems

Ph.D. Edgardo Cañón-Tapia

Ph.D. Emily R. Johnson

erjohnson@usgs.gov

This session seeks contributions on geochronology, structure, and tectonics of monogenetic volcanoes at any spatial or temporal scale on Earth and other planets. Studies that integrate investigations of volcano-tectonic processes and eruption dynamics are especially welcome, as are presentations addressing the relation between tectonic setting and monogenetic volcanism, both local and regional.

Contributions addressing pre-eruptive processes related to the shallow accumulation and the transfer of magma approaching the surface, as well as the evolution of individual monogenetic volcanoes or entire monogenetic fields are also welcome. The multidisciplinary approach of this session can includes perspectives provided by geochronology, structural geology, tectonics, geodesy, ground-based geophysical and geochemical methods, remote sensing, analog modeling, GIS analyses, statistical analyses, spatial distribution, and geomatic tools, as well as geology and geophysics in general.

Geochemistry, petrology, and petrological modeling at monogenetic volcanism

Conveners:

This session includes scientific contributions about magmatic processes that permit us to understand the magma transfer from the mantle or any source at some intermediate depth to the surface, such as magma ascent, magma mixing, magma chamber replenishment, fractional crystallization, and crustal assimilation. Also, all presentations will be on general topics related to monogenetic or small-volume volcanoes. The uniqueness of the magma source characteristics from different geodynamic contexts of mafic, intermediate, or felsic compositions will addressed.

Contributions highlight the complexity of monogenetic eruptions using field observations, mineralogical, geochemical, and isotopic data, as well as analog models of dike propagation, experimental petrology of magma ascents, and diffusion timescale records based on the distributions of the chemical compositions in rocks and minerals.

Lakes in monogenetic systems: Sedimentary record of paleontology, climate change and hydrochemistry

Conveners:

This session addresses multidisciplinary studies about the sedimentary record of paleontology, climate change, and hydrochemistry in hydrological systems associated with monogenetic volcanoes (e.g., crater lakes, maars, explosion craters, etc.). The chemical compositions of lakes are influenced by the climate, the hydrology and hydrogeology, the microorganisms, and internal parameters mainly represented by the hydrothermal system beneath them. Therefore, these hydrological systems associated with monogenetic volcanoes are laboratories of diverse biological and chemical activities, permitting us to provide insight into climate evolution, ecological reconstructions, hydrochemistry, and human impact on natural systems.

In addition, contributions from paleontology, sedimentology of the lake, physical and biological limnology of the lake water, hydrochemistry and geochemistry of water and dissolved gases, and climate proxies, among many others.

Volcanic hazard and risk assessment in monogenetic volcanic fields

Conveners:

This session addresses risk assessment and mitigation of hazards related to monogenetic volcanic systems. Despite the relatively small volumes of magma involved in monogenetic eruptions, they present significant hazards, including intense effusive activity producing extensive lava flows, and high-energy explosive activity generating pyroclastic surges and ash falls that can potentially generate catastrophic local or regional consequences.

Unlike polygenetic volcanoes, once an eruption ends, monogenetic volcanoes do not reactivate and each new eruption produces a new edifice. This results in the clustering of numerous volcanoes, forming volcanic fields with dozens or hundreds of volcanic edifices scattered over extensive geographical areas up to several tens of thousands of square kilometers. This means that despite the smaller size and potential impact of monogenetic eruptions, the uncertainty surrounding the location of future eruptions poses a challenge for volcanic hazard assessment and risk management. Population growth and land transformation as well as the development of infrastructures and society in general, exert increasing pressure on territories where volcanic hazards exist.

This situation illustrates the necessity to improve volcanic risk management, land use planning, as well as preparedness for future emergencies in areas close to monogenetic volcanic activity. This session contributes from various approaches, including field studies, remote sensing, numerical modeling, geophysical and statistical methods, geochemical and petrological studies, monogenetic volcanic hazards assessment, spatio-temporal forecasting, and dynamic hazard and impact models.

Geoheritage, geotourism, and geoconservation in volcanic areas

Conveners:

This session includes scientific contributions that address the values of monogenetic volcanism in geoheritage, geotourism, and geoconservation. Monogenetic volcanoes carry significant geoheritage value if their eruptions influence human society, have high aesthetic value, or are used as reference areas to describe unique volcanic processes. They are a very suitable subject for geoeducation and to promote volcanology to the general public, particularly for demonstrating the variety of volcanic hazards. They may also be important for conserving biodiversity and be related to key cultural sites, which makes them relevant for geoconservation and geotourism, which may be through geopark development.

This session includes evaluation methods to define the geoheritage values of monogenetic volcanoes, the interaction of human societies with monogenetic fields especially linking social studies, indigenous world views and art, as well as geotourism, geoconservation, geopark assessment, archaeology, and economic and social aspects.
