Late Miocene paleo-geomorphology of the Bakony-Balaton Highland Volcanic Field (Hungary) using physical volcanology data

open access: yesZeitschrift Für Geomorphologie, 1999
A new view is presented of the Bakony-Balaton Highland Volcanic Field (BBHVF), Hungary, active in late Miocene and built up of ca. 100 mostly alkaline basaltic eruptive centers, scoria cones, tuff rings, maar volcanic complexes and shield volcanoes.

Physical volcanology and eruption dynamics of peralkaline agglutinates from Pantelleria

Journal of Volcanology and Geothermal Research, 1997
Peralkaline rhyolitic lava-like lobes showing direct evidence for a spatter-fed origin are associated with eruptive centres that document a transition from explosive to effusive fountain-fed activity. Owing to the preservation of spatter clasts, clast dimensions can be used to model the eruptive dynamics of these deposits.

Physical volcanology of the Gubisa Formation, Kone Volcanic Complex, Ethiopia

Journal of African Earth Sciences, 2014
Despite their significance for understanding the potential environmental factors involved in hominin evolution in Ethiopia, very few modern volcanologic studies have been carried out on the Quaternary calderas and associated silicic tephra deposits of the Ethiopian Rift.

The AD 1362 Öræfajökull eruption, S.E. Iceland: Physical volcanology and volatile release

Journal of Volcanology and Geothermal Research, 2008
Abstract The explosive rhyolitic eruption of Oraefajokull volcano, Iceland, in AD 1362 is described and interpreted based on the sequence of pyroclastic fall and flow deposits at 10 proximal locations around the south side of the volcano. Oraefajokull is an ice-clad stratovolcano in south central Iceland which has an ice-filled caldera (4–5 km ...

Physical volcanology and geological relationships of the Jurassic Ferrar Large Igneous Province, Antarctica

Journal of Volcanology and Geothermal Research, 2008
Abstract The Ferrar Large Igneous Province forms a linear belt for 3500 km along the Transantarctic Mountains, and as a geochemical province extends into southeastern Australasia. The principal components of the Ferrar are: intrusive — Ferrar Dolerite sills and dikes, and Dufek intrusion; pyroclastic — the Prebble, Mawson and Exposure Hill Formations;
