• Minasgeraisite-(Y): Mineral information, data and localities.

    www.mindat.org/min-2716.html The validity was actually confirmed together with a rather strong redefinition, by Cooper & Hawthorne (2018). The authors suggest formation of a triclinic subgroup within the gadolinite-datolite group to which the minasgeraisite-(Y) now belongs. Originally thought to be: CaBe 2 Y 2 Si 2 O 10.

  • MINASGERAISITE - (Y) (Calcium Yttrium Beryllium Silicate)

    www.galleries.com/Minasgeraisite Minasgeraisite is a rare yttrium beryllium silicate. It has a nice color, pale lavender to purple, that is rather attractive. Minasgeraisite is named for the most famous of mineral localities, namely Minas Gerais, Brazil.The name means "mining region" and is the source for not only this rare silicate but for literally hundreds of thousands (if not millions) of fine mineral specimens.

Members of the Minasgeraisite-(Y)- Hingganite-(Y) series are the primary Be phase at Strange Lake. A portion of these spheres have been pseudomorphed to a mixture of cerium-bearing phases according to analysis by Stefano del Magro, September 9, 2016.
