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...
This work presents a summary on the development of studies of historical earthquakes in Armenia and adjacent parts of Turkey and Iran. Since ancient times, this region has been an arena where active g...
The occurrence of a former subaerial volcanic edifice off the Volturno River (Tyrrhenian Sea, Gulf of Gaeta) in the 41°N parallel is suggested by joint interpretation of multichannel seismic lines and...
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...
河南理工大学地球科学课件chepter 6 Volcanoes and Volcanism
By analyzing the speed of seismic waves generated by earthquakes, scientists have shown that temperature differences deep within Earth’s mantle control the elevation and volcanic activity along mid-o...
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...
The Toprakkale (Osmaniye) region, located in the Yumurtalık fault zone in southern Turkey, contains Quaternary volcanic rocks, shown by their mineralogical and petrographical features to be alkal...
Early Cretaceous (~129 Ma) silicic rocks crop out in SE Uruguay between the Laguna Merín and Santa Lucía basins in the Lascano, Sierra São Miguel, Salamanca and Minas areas. They are mostly rhyol...
Andean volcanism occurs within the Andean Volcanic Arc (AVA), which is the product of subduction of the Nazca Plate and Antarctica Plates beneath the South America Plate. The AVA is Earth's longest bu...
Models of explosive volcanism     Models  explosive volcanism       2009/11/16
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...
