Greenish-grey prismatic prismatine in a matrix of quartz with some biotite, garnet, sillimanite, and pyrite. Prismatine crystals measure up to 1.2 cm in length and up to 1.5 mm in diameter and constitute about 30% of the piece.

Hincks Bridge, Lac-Sainte-Marie, La Vallée-de-la-Gatineau RCM, Outaouais, Québec, CanadaHincks Bridge looking NW towards Lac-Sainte-Marie. The town boundary is just a few hundred metres on the other side of the bridge. The "kornerupine" outcrops are on both sides of the highway just before the bridge.

"Kornerupine" outcrop
Hincks Bridge, Lac-Sainte-Marie, La Vallée-de-la-Gatineau RCM, Outaouais, Québec, CanadaThe outcrop on the NE side of the highway immediately SW of Hincks Bridge. This occurrence is referred to the "Kazabazua Kornerupine Occurence"; however as a result of a reclassification of the kornerupine-prismatine series (Min.Mag.V60p483-491,1996,E.S.Grew et al.) most if not all the "kornerupine" is Prismatine.
