Barian Muscovite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
(K,Ba)(Al,Mg)2(AlSi3O10)(OH)2
Name:
Named in 1933 by Lawson H. Bauer and Harry Berman for its chemical relationship to muscovite, but the mineral from Franklin, New Jersey, USA was shown not to be Ba-dominant. In 1867 James Dwight Dana named oellacherite in honor of Josef Oellacher [February 16, 1804 Pressburg, Austria - August 16, 1880 Innsbruck, Austria], a chemical pharmacist who first investigated the mineral and thought it was margarite, but oellacherite was eventually proved to be a barian variety of muscovite, as well. The original oellacherite was from Vizze Valley (Pfitsch Valley), Bolzano Province (South Tyrol), Trentino-Alto Adige, Italy.
A variety of Muscovite
