About Wittite
Formula:
Pb9Bi12(S,Se)27
Colour:
Light lead-gray
Lustre:
Metallic
Hardness:
2 - 2½
Crystal System:
Monoclinic
Name:
Named after T. Witt, Swedish mining engineer at the Falun Mine.
First Recorded Locality:
Studies of the distribution of Se in the crystal structure are necessary to determine whether wittite is a Se-rich variety of cannizzarite or an independent species (Moëlo et al., 2008).
