VS14 Unlocking the Enigma of Monogenetic Volcanism from a Historic Perspective to the Most Novel Recent Approaches

Description
In 2015, Prague will host the IAVCEI General Assembly as part of the IUGG Conference. Prague is the heart of Central Europe where large number of alkaline basaltic volcanic fields are located. These are generally considered to be typical intracontinental monogenetic volcanic fields and they have been the subject of intensive geological research in the past 150 years. Many of these volcanic fields provided either the first or one of early ideas that formed the fundamental basis of our understanding of the formation of small-volume basaltic (monogenetic) volcanoes. On the basis of this historical fact the IAVCEI Commission on Monogenetic Volcanism offers a technical symposium on monogenetic volcanism based on the past decade of advances in our understanding, especially to demonstrate the evolution of knowledge on a historic scale. Monogenetic volcanoes are the most common volcanoes on Earth and in the Solar System. They can form in nearly any geological setting and their eruption mechanisms can span from phreatomagmatic explosive to purely effusive styles, both under water or in subaerial environments. It seems that monogenetic volcanoes can be fed through plumbing systems directly linked to deep source regions, but there are examples where volcanic eruptions have been triggered by magma sourced near surface storage zones. As a consequence, while basaltic systems are by far the most common among monogenetic volcanoes, the full range of magmatic compositions does exist. Monogenetic volcanoes “per sensu stricto” are those that are fed from a single magma batch directly from mantle sources; therefore their eruption durations are usually short, they are chemically simple and their volcanic edifices are normally small. In the past decade research has demonstrated that volcanoes generally considered to be monogenetic are in fact far more complex, and can be built through volcanic processes involving multiple magma batches that erupted over a long time period; the resulting volcanic edifices, while remaining relatively small, can be very complex. On the basis of these recent advances, many groups have raised questions on how monogenetic are monogenetic volcanoes, and how practical it is to define a volcano as monogenetic. In the past decade we have seen numerous research outputs targeted at these issues. In general, while these questions are valid and form the driving force of research on monogenetic volcanoes, it is undeniable that defining a volcano to be monogenetic has a fairly similar meaning for most of us (eg. relatively small, short lived, normally basaltic and forming dispersed volcanic fields usually in intracontinental settings). In this symposium we wish to invite researchers to present their latest results targeting this fundamental area in volcanology. We would particularly like to encourage submissions on research expanding the source to surface model for this type of volcanism, targeting the petrogenesis, magma segregation, transport and shallow level eruption dynamics that are responsible for the birth of this type of volcanism. Research outputs that find novel approaches to determine the longevity, chemical and sedimentological complexities of volcanic edifices and associated volcaniclastic successions associated with this type of volcanism are especially welcomed. The symposium also intends to call for presenters worked on understanding the consequences of the recent advances in understanding monogenetic volcanism from a volcanic hazard and eruption scenario perspective. Researchers presenting work based on those monogenetic fields from the “birthplace” of understanding monogenetic volcanism in Central Europe are intended to form a vital part of this symposium as well.
