About Carrollite
Formula:
CuCo2S4
More specifically Cu1.2+(Co2.4+)2(S1.5-)4 (Pattrick et al., 2008).
Colour:
Bright silver color
Lustre:
Metallic
Hardness:
4½ - 5½
Specific Gravity:
4.5 - 4.8
Crystal System:
Isometric
Member of:
Name:
Named in 1852 by William Leonard Faber after the type locality in Carroll County, Maryland, USA.
Type Locality:
Isostructural with:
Thiospinel Group. Copper in carrollite was recently shown to be monovalent (Pattrick et al., 2008), confirming an earlier study (Nakai et al., 1978).
Natural samples commonly contain Ni; in samples from the Siegerand ore province, a solid solution exists between CuCo2S4 and Cu(Ni,Co)2S4 in which Ni can replace 50% of the Co (Wagner & Cook 1999).
