Russian meteorite yields new mineral, uakitite 07AUG2018

 Russian meteorite yields new mineral, uakitite

Russian gold prospectors find meteorite containing

a new mineral that had never before been seen on Earth.

The mineral came from the Uakit meteorite, named for the

Russian location where it was found. The new mineral is

named uakitite and announced at the 81st Annual

Meeting of The Meteoritical Society 2018 (LPI Contrib. No. 2067)
