Lemmleinite-Ba - Sold

Lemmleinite-Ba is a hydrous sodium potassium barium titanium silicate, and a member of the labuntsovite group (Chukanov et al. 2002). Originally Khomyakov et al. (1999) named lemmleinite after Georgy Lemmlein (1901-1962), Russian mineralogist and crystallographer. When Chukanov et al. (2001) found a barium analog, they applied a Levinson modification naming lemmleinite-Ba, also changing the original lemmleinite to lemmleinite-K.

Lemmleinite-Ba forms red-orange to 2 mm covering natrolite crystals in a cavity of carbonatite matrxic. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
