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...

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...
