One of the world's best Strontianite localities is Oberdorf an der Laming, Styria, Austria, which has produced large, sharp, and beautifully colored crystals of this mineral. Excellent Strontianite specimens have come from Westphalia, Germany at the Dreislar Mine, Winterberg; and the Phoenix quarry, Beckum, where large veins of this mineral contain pockets of fine crystals. A famous locality, from which the name Strontianite is derived, is Strontian, Argyllshire, Scotland. Other European localities are the Ratum quarry, Vosseveld, Netherlands; the Cavradi Gorge, Grischun, Switzerland; and Piagnolo, Campegli, and Casazzascany, Italy.
In the U.S., arguably the best Strontianite locality is the Minerva No. 1 Mine, Cave-in-Rock, Hardin Co., Illinois. Another excellent occurrence is Lime City Quarry, Lime City, Wood Co., Ohio. Pennsylvania contains several important limestone
quarries where this mineral is found, specifically the Meckley Quarry, Mandata, Union Co.; Winfield, Union Co., Pennsylvania; and Lime Ridge, Mt. Pleasant Mills, Snyder Co. Other Strontianite localities include Schoharie, Schoharie Co., New York; the Holston River Quarry, Dublin, Pulaski Co., Virginia; the Strontium hills near Barstow, San Bernardino Co., California; and the Alverson Mine, Lake Conner, Skagit Co., Washington.
In Canada, Strontianite comes from Mont Saint-Hilaire, Quebec; and the Lafarge Quarry, Dundas, Ontario.
