Concept

The IAVCEI 5th Volcanic Geology Workshop follows the footsteps of the previous meetings on this emerging science in the volcanology community. The workshop series started in Madeira, 7-11 July 2014 as the 1VGW marked the event to establish the IAVCEI Commission on Volcanic Geology. This meeting provided the basis to call experts to “rejuvenate” traditional volcanic geology researches in the volcanic community and provide a platform to exchange ideas of people working on various volcanic terrains, commonly with geological mapping purposes. The workshop got great attention, and the initial momentum culminated in the organisation of the Second Volcanic Geology Workshop in Prague, Czech Republic in conjunction of the IUGG General Assembly.

The Third Volcanic Geology Workshop took the participants to an active volcanic region where various type of volcanoes actively forming the landscape through various eruptions styles feeding terrestrial and marine volcaniclastic sedimentary successions in the Etna and Aeolian Islands region in Italy. This workshop provided an excellent insight to modern volcanic settings in the world probably best studied regions. This workshop outlined several issues associated with volcanic geology applications mostly in regard to geological mappings on volcanic terrains that need to be discussed. Particularly the problem to apply actual geological concepts to ancient volcanic terrains and utilizing their values for geological mappings in various scales concluded to be major knowledge gaps in volcanology.

As a result of this discussion the Fourth Volcanic Geology Workshop took the participants to the Eastern Carpathian Miocene to Pleistocene arc-volcanic regions where geological mappings are hindered not only by the ancient nature of exposed and preserved volcanic formations but also their general poor exposure level under heavy vegetation cover. This workshop was an eye-opener to many that ancient and modern volcanic systems need to be understood and link better to be able to generate sensible geological maps to various scales.

On the basis of this outcome the current Fifth Volcanic Geology Workshop provides field based experience to the participants to see the volcanic facies architecture of active but long-lived intermediate composite to silicic caldera volcanoes in an atypical arc setting along the Taupo Volcanic Zone in New Zealand. This workshop will take the participants to iconic locations from where basic concepts in volcanology emerged such as ignimbrite depositions, volcaniclastic sedimentary respond to major volcanic eruptions, ring plain concepts of stratovolcanoes, volcano collapses and their landscape modifying effects, small volume monogenetic volcanism associated with central volcanoes and application of tephrastratigraphy and chronology in development of mapping units, just few key areas New Zealand volcanic geology science is famous for.

We hope that this workshop will provide an excellent opportunity to exchange experiences of people working on ancient terrains and those more associated with active volcanism. The workshop also intends to provide a platform for experts to share their view in a relaxed way rarely met from seemingly far sub-disciplines.
