Pyrrhotite-5C

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Fe9S10
Crystal System:
Monoclinic
A polytype of Pyrrhotite

The crystal structure of a 5C pyrrhotite from Copper Cliff Mine, Sudbury, Canada, was described by de Villiers et al. (2009), as orthorhombic, space group Cmce. Later redetermined as monoclinic, space group P21, by Liles & de Villiers (2012).
