Researchers investigate the effects of oxygen content on the melting of mantle rocks and the formation of early Earth magma It is widely accepted that the early Earth largely consisted of molten magma ...

A new 'geospeedometer' that can measure the amount of time between the formation of an explosive magma melt and an eruption confirms that the process took less than 500 years in several ancient ...

Earth Scientists at Cambridge University have analyzed rock and crystal samples from magma that was extruded in the pre-historic Borgarhraun eruption in Iceland and found that the magma body reached ...

Hot mafic magma cannot rise through the silicic magma, but it can mix. When it does, the mafic magma recharges the silicic magma, creating a hotter mixture that can pass through the viscosity filter.

Until now, the scientific community debated the starting point of liquid mantle solidification: did it begin deep within the Earth and progress toward the surface, or vice versa? Through advanced ...

Scientists have shown how the freezing of a ‘slushy’ ocean of magma may be responsible for the composition of the Moon’s crust. The scientists, from the University of Cambridge and the Ecole normale ...
