About these Specimens of Sodalite var. Hackmanite
Although sodalite is a relatively common mineral at Mont Saint-Hilaire, well-formed crystals are quite rare. These specimens are from a pocket collected by Gilles Haineault in 1994. The specimens from this pocket are entirely distinctive, as the hackmanite crystals are coated with albite crystals.
