Carrollite
Carrollite was named after its occurrence in Carroll Co. Maryland, US, at the Patapsco mine, Sykesville.
Carrollite is a sulfide of copper and cobalt, sometimes with substitution of nickel for the metal ions.   It belongs to
the Linnaeite group. Carrollite occurs in hydrothermal vein deposits and can be identified in the field by its color
variations, such as gray, copper red, light gray, and steel. Its opaque form has indistinct cleavage and a metallic
luster. It is often associated with minerals such as Tetrahedrite, Linnaeite, Siegenite, Polydymite, Digenite,
Pyrite, Chalcopyrite, Bornite, Chacocite, Pyrrhotite, Sphalerite, Millerite, Gersdorffite, Ullmannite, Cobaltoan
Calcite, and Djurleite.
