Rudashevskyite

A valid IMA mineral species
This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Fe,Zn)S
Type material has the empirical formula (Fe0.61Zn0.35Mn0.04Cu0.01)Σ=1.00S1.00. The high Zn content stabilises the sphalerite-type structure of the mineral.
Colour:
Black
Lustre:
Resinous, Sub-Metallic
Specific Gravity:
3.79 (Calculated)
Crystal System:
Isometric
Name:
Named for Nickolay Semenovich Rudashevsky (Николай Семенович Рудашевский) (1944-), St. Petersburg, Russia, for his contributions in the study of ore minerals.
Polymorph of:
Buseckite, Keilite, Troilite
Sphalerite group.
The iron(II) analogue of sphalerite, browneite, etc.
Compare the pure iron sulphides troilite (FeS) and pyrrhotite (Fe1-xS).
