About Enneasartorite
Wolfgang Sartorius von Waltershausen
Formula:
Tl6Pb32As70S140
Colour:
Lead-grey, grey
Lustre:
Metallic
Hardness:
3 - 3½
Specific Gravity:
5.1 (Calculated)
Crystal System:
Monoclinic
Member of:
Name:
Named for it relationship to sartorite and for ennea- (Greek for nine) for the nine-fold superstructure of a 4.2 Å subcell. The unofficial term M-sartorite has been used to described more than one species of hepta-, ennea- and hendekasatroite. The root name is for Wolfgang Sartorius von Waltershausen (1809 - 1876) Professor of Mineralogy, University of Göttingen, Germany.
Type Locality:
Sartorite homologous series.
Physical and optical properties similar to heptasartorite and hendekasartorite. Careful quantitative chemical analysis and/or single-crystal X-ray diffraction is needed to distinguish them.
NOTE: Enneasartorite corresponds to the "sartorite" described by Berlepsch et al. (2003).
