Cobaltite from
Brazil Lake occurrence, Foster Township, Unorganized North Sudbury District, Sudbury District, Ontario, Canada


Locality type:Occurrence
Classification
Species:Cobaltite
Formula:CoAsS
Comments:Many specimens found in a zone at the contact between a large quartz vein and gabbro host rock. The quartz vein is up to 15m wide has a vertical dip and strikes North.
The contact zone varies in width and consists of mainly grey coarse grained iron rich dolomite with lesser amounts of actinolite, fine grained calcite, talc (fine to coarse grained), pyrrhotite, pyrite, chalcopyrite and quartz. Cobaltite occurs mainly in the grey dolomite but is also found abundantly in a mixture of coarse actinolite and fine grained calcite and occasionally in massive pyrrhotite, and rarely in quartz.
Habit:cubic crystals ( up to 3.0 cm) and more rarely cubo-pyritohedral crystals
