About RobinsoniteHide

Formula:
Pb4Sb6S13
Colour:
Lead-gray
Lustre:
Metallic
Hardness:
2½ - 3
Specific Gravity:
6.7
Crystal System:
Monoclinic
Name:
Named in 1951 by Leonard Gascoigne Berry, Joseph John Fahey, and Edgar Herbert Bailey in honour of Stephen Clive Robinson (12 September 1911, Pincher Creek, Claresholm Census Division, Alberta, Canada - 13 September 1981, Saanichton, Capital Regional District, British Columbia, Canada), Canadian mineralogist, Geological Survey of Canada, and former Professor of Mineralogy, Queen’s University, Kingston, Ontario. Robinson synthesized the compound in 1947 (Robinson, 1948) before the mineral was found in nature.
The structure as in case of, e.g., boulangerite, jamesonite, and zinkenite, comprises interconnected SbS3 groups.

Fluorescence of RobinsoniteHide

Not fluorescent in UV

Other InformationHide

Notes:
Raman bands connected with stretching and bending of the SbS3 groups are between 350 and 175 cm-1.

Etching with 40% KOH occurs in a few minutes, distinguished from boulangerite which remains unaffected for up to 10 minutes.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
