WFS News: Earth’s core and mantle separated in a disorderly fashion

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Plumes of hot rock surging upward from the Earth’s mantle at volcanic hotspots contain evidence that the Earth’s formative years may have been even more chaotic than previously thought, according to new work from a team of Carnegie and Smithsonian scientists published in Nature. It is well understood […]

Why rocks flow slowly in Earth’s middle mantle

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev For decades, researchers have studied the interior of the Earth using seismic waves from earthquakes. Now a recent study, led by Arizona State University’s School of Earth and Space Exploration Associate Professor Dan Shim, has re-created in the laboratory the conditions found deep in the Earth, and used […]

WFS News: Early organic carbon got deep burial in mantle

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Rice University petrologists who recreated hot, high-pressure conditions from 60 miles below Earth’s surface have found a new clue about a crucial event in the planet’s deep past. Their study describes how fossilized carbon — the remains of Earth’s earliest single-celled creatures — could have been subsumed and […]

Presence of Magnesium oxide: From Earth to super-Earth

The mantles of Earth and other rocky planets are rich in magnesium and oxygen. Due to its simplicity, the mineral magnesium oxide is a good model for studying the nature of planetary interiors. New work from a team led by Carnegie’s Stewart McWilliams studied how magnesium oxide behaves under the extreme conditions deep within planets […]
