Group: Carbonates
Chemical composition: (Ni,Mg,Fe++)CO3
Colors: Light green
Hardness: 4.5 to 5
Formation: Hexagonal crystals
Principal Sources: Quebec, Canada and Western Australia
Special Notes: The name Gaspeite comes from the Gaspe Peninsula in Quebec, where the mineral was first found. Gaspeite is formed from a similar process to the weathering of other sulfide minerals to form carbonate minerals. The sulfide minerals which are weathered to produce gaspeite are pentlandite, violarite, millerite and rarely nickeline.
