In a nutshell Scientists have solved the mystery of how earthquakes can occur 420 miles deep inside Earth, where extreme ...

The magnitude 7.9 Bonin Islands earthquake sequence, which ruptured deep within the earth near the base of the upper mantle, did not include an aftershock that extended to record depths into the lower ...

Instead, their study found a distribution of aftershocks that is compatible with a 12-kilometer sliver of a mantle mineral called olivine that could shed light on how deep earthquakes can occur.

The team then swapped the synthetic mineral with olivine, a natural iron-laden rock, to better mimic real-world scenarios. They further optimized the process by adding a copper catalyst and ...

Specifically, chromite nanocrystals can grow outward from the surface of olivine like "mushrooms after rain," the research team told the Global Times on Wednesday. The findings may serve as an ...

Other asteroids aren't the same—they tend to be richer in olivine. Based on that data and its tumbling motion, scientists conclude that it is ejecta from an impact on the moon. If that's the ...

In the asthenosphere, molten olivine moves with a convection current, radiating heat outward from the Earth's interior. The rigid lithosphere floats on the slowly flowing asthenosphere ...
