A new occurrence of the rare Li amphibole, holmquistite, has been discovered near Barraute, Quebec. It occurs at or near the contact of spodumene pegmatites and hornblende-rich rock. A chemical analysis indicates a composition close to Li 2 (Mg,Fe'') 3 (Al,Fe''') 2 Si 8 O 22 (OH) 2 . The holmquistite is orthorhombic, with a = 18.30, b = 17.69, and c = 5.30. The optical and physical properties are similar to those of other holmquistites cited in the literature.
