Volcanism is sometimes like food poisoning, where the Earth spews forth unstable material. New research suggests that a significant pulse of volatile carbon was released from the Earth’s mantle around...
Submarine volcanism remains underexplored and underexamined – ¾ of Earth lies beneath water, and a substantial majority of Earth’s volcanic eruptions take place in this subaqueous realm.This conf...
AAPG Asia Pacific Region has selected the above topic for its second GTW in New Zealand – a global showcase for geological processes and systems with its active plate boundary setting and complex mult...
The Antler and Sonoma orogenies occurred along the southwest-trending passive Pacific margin of North America during the Paleozoic concluding with the accretion of the McCloud Arc. A southeast-trendin...
One extremely young volcano (0.05–1 Ma) and other young volcanoes (1.8, 4.2, 6.0, and 8.5 Ma) composed of strongly alkaline magma were recently discovered on the abyssal plain of the Early Cretaceous...

We describe a series of models which illustrate the controls upon the evolution of an erupting mixture of ash and gas during an explosive volcanic eruption. For large eruption rates, material typicall...
Explosive eruptions from volcanoes are recorded in the stratigraphic record throughout the Phanerozoic. The most visible evidence of these eruptions is generally in the form of preserved tephra layers...
The Jurassic volcanic rocks in the centre of the northern zone (south of Trabzon City) provide important constraints on the evolution of Pontides. The investigated volcanic rocks form a transitional s...
The Orduzu volcanics, which are part of the Yamadağ volcanics in the Malatya region, include rhyolite, rhyolitic dykes, trachyandesite and basaltic trachyandesitic dykes. Mafic globular occurrenc...
The eastern part of the Anatolian plateau in eastern Turkey has experienced dramatic landscape evolution in the Late Cenozoic, surface uplift having been associated with the disruption of former lake ...
