Latest Flood basalt Stories
Like a stream of air shooting out of an airplane's broken window to relieve cabin pressure, scientists at Scripps Institution of Oceanography at UC San Diego say lava formations in eastern Oregon are the result of an outpouring of magma forced out of a breach in a massive slab of Earth.
Around 250 million years ago, at the end of the Permian geologic period, there was a mass extinction so severe that it remains the most traumatic known species die-off in Earth’s history.
New research from Matthew Jackson and Richard Carlson proposes that the remnants of six of the largest volcanic events of the past 250 million years contain traces of the ancient Earth's primitive mantleâ€”which existed before the largely differentiated mantle of todayâ€”offering clues to the geochemical history of the planet.
Analysis of new images of a curious â€œhot spotâ€ on the far side of the Moon reveal it to be a small volcanic province created by the upwelling of silicic magma.
Volcanic activity more than 200 million years ago may have helped dinosaurs become and remain the world's dominant species by causing the mass extinction of rivals, researchers claim in a recent study.
By Jolley, David W Widdowson, Mike; Self, Stephen Abstract: Research from biological and geological sources has highlighted the role of volcanoes in the outgassing of P, and thermal fixation and subsequent atmospheric oxidation of NO^sub x^ in volcanic environments.
For the first time, researchers have taken a detailed look at what lies beneath all of Icelandâ€™s volcanoes â€“ and found a world far more complex than they ever imagined.
Scientists reported on Thursday that they believe a series of volcanic eruptions in modern day India may have been the cause of mass extinctions of species including dinosaurs over the last 545 million years.
Earth history has been punctuated by several mass extinctions rapidly wiping out nearly all life forms on our planet. What causes these catastrophic events?
The June issue of GEOLOGY covers a wide variety of potentially newsworthy subjects.
- The deadly nightshade, Atropa Belladonna, which possesses stupefying or poisonous properties.
- A sleeping-potion; a soporific.
- To mutter deliriously.
