About Petrukite
Formula:
(Cu,Fe,Zn,Ag)3(Sn,In)S4
Colour:
Brown to gray
Hardness:
4½
Crystal System:
Orthorhombic
Member of:
Name:
Named in honor of William Petruk (30 June 1930, Norquay, Saskatchewan, Canada), mineralogist with Natural Resources Canada, who noted the possible existence of the mineral in his study of the Mount Pleasant ore deposit (Petruk 1973).
An orthorhombic member of the Stannite Group.
The symmetry reduction may be due to a small In content.
