Unusual diamonds reveal secrets of Earth's mantle.
Diamonds with opposing materials offer clues to Earth's mantle composition.
Why it matters
- Confirms diamond formation through chemical reactions in the mantle.
- Provides insights into the chemical processes deep within Earth.
By the numbers
- Diamonds formed at depths of 280-470 km below Earth’s surface.
- Two diamond samples studied.
The big picture
- Supports theoretical models of mantle chemistry.
- Suggests kimberlite rocks may originate deeper than previously thought.
What they're saying
- Experts say the findings provide real-world evidence for mantle chemistry theories.
- Some readers note paywalls and share personal anecdotes.
Caveats
- Findings based on only two diamond samples.
- Does not rule out other diamond formation processes.
What’s next
- Further research on nickel atoms in diamonds.
- More studies to confirm and expand findings.
