Member of:Mica Group
Name:Named in 1823 by Johann Nepomuk von Fuchs. The earlier name (1820), by Friedrich Mohs, for this mineral was "pearl-mica", because of its luster.


Mica Group.

Hintze (Vol. 2, 1897) gives Sterzing (Vipiteno), South Tyrol as the TL of margarite and refers to Mohs (1820). In fact, Mohs described the mineral, but did not provide an analysis. Therefore, according to von Zepharovich (1873), Greiner Mt. has to be regarded as the TL, based on the data provided by Senger.
