A Series of Fortunate Events:Antarctic Zircons Tell Story of Early Volcanism（图）
Series of Fortunate Events Antarctic Zircons Early Volcanism
2017/12/18
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...
2017年海底火山查普曼会议（Chapman Conference on Submarine Volcanism:New Approaches and Research Frontiers）
2017年 海底火山查普曼 会议
2017/1/20
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...
Influence of Volcanism and Associated Magmatic Processes on Petroleum Systems
Igneous activity source rock maturation

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...
Evidence of historical seismicity and volcanism in the Armenian Highland (from Armenian and other sources)
historical seismicity volcanism catalogue
2015/9/14
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...

Hot mantle drives elevation, volcanism along mid-ocean ridges
Hot mantle drives elevation volcanism along mid-ocean ridges
2014/4/16
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...

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...
Petrogenesis of Early Cretaceous silicic volcanism in SE Uruguay: The role of mantle and crustal sources
Uruguay Paraná-Etendeka rhyolite lower crust crustal contamination
2017/8/9
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...
Volcanism and associated hazards: the Andean perspective
Volcanism associated hazards Andean perspective
2010/1/28
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...
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...
Volcanism and its Contribution to Mudrock Genesis
