A new mineral called Grahampearsonite has been discovered and named after renowned Canadian geochemist Graham Pearson, an expert in mantle geology and mineralogy. The mineral, found inside a diamond from Brazil, provides insights into the composition and water content of the Earth's deep interior, over 300 kilometers below the surface.

Why it matters

The discovery of Grahampearsonite highlights the ongoing process of scientific exploration and the collaborative nature of research. It showcases how diamonds can act as time capsules, preserving secrets about the planet's history and composition that are crucial for understanding the Earth's deep mantle.

The details

Grahampearsonite is composed of calcium, phosphorus, and oxygen, and was found encased within a diamond that crystallized at extreme depths. This rare mineral offers a unique window into the conditions and chemistry of the Earth's mantle, an area that remains largely mysterious. The International Mineralogical Association named the new find in honor of Pearson's lifetime of contributions to mantle geology.

  • Grahampearsonite was discovered in a diamond from Brazil.
  • The new mineral was officially named in 2026 by the International Mineralogical Association.
