Summary:
- The discovery of an unusual mineral called bridgmanite in a meteorite challenges the prevailing models of how the Earth's interior evolved chemically over time.
- Bridgmanite is the most abundant mineral in the Earth's lower mantle, but it is extremely rare on the surface due to the high pressure and temperature conditions required for its formation.
- The presence of bridgmanite in the meteorite suggests that the Earth's interior may have been more chemically complex and dynamic than previously thought, with implications for our understanding of the planet's geological history and evolution.
