About Margarite
Formula:
CaAl2(Al2Si2O10)(OH)2
Colour:
Grayish, pale pink, yellow, green. Colorless in thin section.
Lustre:
Vitreous, Pearly
Hardness:
3½ - 4½
Specific Gravity:
2.99 - 3.08
Crystal System:
Monoclinic
Member of:
Name:
First named 'pearl-mica' by Friedrich Mohs (1820) because of its luster. The current name was given in 1823 by Johann Nepomuk von Fuchs, from the Greek for pearl.
Type Locality:
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.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars.
