Scientists have solved the mystery of how earthquakes can occur 420 miles deep inside Earth, where extreme pressure and heat ...
UNLV-led research details early insights from NASA’s Perseverance rover; Specimens due back on Earth in the 2030s.
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.
Specifically, chromite nanocrystals can grow outward from the surface of olivine like "mushrooms after ... growth patterns and mineral composition of lunar crystals show clear differences compared ...
The outer mantles of many rocky planets are dominated by either garnet or olivine, the mineral from which we extract peridot. Garnet is a stiffer mineral than olivine, more viscous even when fully ...
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 ...
To evaluate the method’s real-world applicability, the team substituted the synthetic minerals with olivine, a naturally occurring iron-rich rock. When combined with a copper catalyst and heated to ...
