Earth's Most Abundant Material Finally Gets a Name

"The team examined a section of the highly shocked L-chondrite meteorite
Tenham, which crashed in Australia in 1879. The GSECARS beamline was
optimal for the study because it is one of the nation?s leading
locations for conducting high-pressure research.

Bridgmanite grains are rare in the Tenhma meteorite, and they are
smaller than 1 micrometer in diameter. Thus the team had to use a
strongly focused beam and conduct highly spatially resolved diffraction
mapping until an aggregate of Bridgmanite was identified and
characterized by structural and compositional analysis."
