Josef Zemann
Formula:
Mg0.5ZnFe3+(Te4+O3)3 · 4.5H2O
Colour:
Brown
Lustre:
Adamantine
Crystal System:
Hexagonal
Member of:
Name:
Named after Josef Zemann (b. 25 May 1923, Vienna, Austria), Professor of Mineralogy, University of Vienna (Austria), in recognition of his outstanding work in crystallography, crystal chemistry, optical mineralogy and spectroscopy, and other fields.
Zn-analogue of kinichilite and keystoneite. Fe-analogue of ilirneyite.
According to Mandarino et al. (1976) zemannite has zeolite-like framework of negatively charged [Zn^2(TeO^3)^3], with large channels parallel to [0001].
