Natural diamonds form under high temperature and pressure conditions in Earth's mantle.
Is it true that natural diamonds form under high temperature and pressure conditions in Earth's mantle?
Yes. Natural diamonds form under high temperature and pressure conditions in Earth's mantle, as supported by experimental petrology and mineralogical studies of mantle inclusions.
Verdict: SUPPORTED · 4 sources for, 0 against · Last checked
The retrieved papers include multiple recent experimental and observational studies on diamond genesis in Earth's mantle under high pressure and temperature conditions. All relevant papers support the claim, and none refute it.
