Maria Aristides Brezina
Formula:
Cr3S4
System:
Monoclinic
Hardness:
3½ - 4½
Name:
Named in 1969 by Theodore E. Bunch and Louis H. Fuchs in honor of Maria Aristides Brezina [May 4, 1848 Wien (Vienna), Austria – May 25, 1909 Wien (Vienna), Austria], past Director of the Mineralogy-Petrology Section of the Natural History Museum, Vienna, Austria. Brezina was one of the most important researchers of meteoritics and helped develop an important early classification of meteorites.
This page provides mineralogical data about Brezinaite.

D : Metal Sulfides, M: S = 3 :4 and 2:3
A : M:S = 3:4
