Overview
Gaspéite, a very rare nickel carbonate mineral, with the formula (Ni,Fe,Mg)CO3, is named for the place it was first described, in the Gaspé Peninsula, Québec, Canada. Gaspéite is the nickel rich member of the calcite group. A solid solution series exists between all members of this group with divalent cations readily exchanged within the common crystal structure. It forms massive to reniform papillary aggregates in fractures, botryoidal concretions in laterite or fracture infill. It is also present as stains and patinas on iron oxide boxworks of gossaniferous material.
