Strontianite is an epithermal (low temperature) hydrothermal mineral that occurs in sulphide veins in
limestone, marl and
also as geodes or concretionary masses in limestone or
clay. It occurs rarely in hydrothermal metallic veins and is common in
carbonatites. Associated minerals include
calcite, harmotome and
Strontianite alters to celestine and is itself also found as an alteration product of
At the Cariboo Mining Division, British Columbia, Canada, strontianite occurs in vein deposits in limestone (Dana).
At the Francon quarry, Montreal, Quebec, Canada, strontianite is very common as aggregates to 10 cm as a late stage mineral in the sill cavities, sometimes as multiple generations (Minrec 37.1.44-46).
At Oberschaffhausen, Bötzingen, Breisgau-Hochschwarzwald, Freiburg, Baden-Württemberg, Germany, strontianite occurs with zeolites (Dana).

At Sierra Mojada, Mun. de Sierra Mojada, Coahuila, Mexico, secondary strontianite occurs with celestine in a lead-silver deposit, and is believed to have formed as an alteration product of celestine (AM 18.345-350).
At the Kirovskii apatite mine, Kukisvumchorr Mt, Khibiny Massif, Murmansk Oblast, Russia, strontianite occurs in late hydrothermal assemblages in cavities of pegmatites associated with kukharenkoite-(La) in a pectolite-aegirine-microcline vein (Minrec 35.4.355).
At Yukspor Mt, Khibiny Massif, Murmansk Oblast, Russia, strontianite is associated with ferricerite-(La) in an aegirine-natrolite-microcline vein in foyaite (Minrec 35.2.176), and with barylite-10 in alkaline pegmatite veins (Minrec 35.4.347).
At Palabora, Limpopo Province, South Africa strontianite was found on one occasion, as single white prismatic crystals to 3 mm associated with iowaite in a carbonate stringer in phoskorite (R&M 92.5.448).
At Brownley Hill Mine, Nenthead, Alston Moor, Eden, Cumbria, England, UK strontianite occurs rarely as white to pale green sprays to 5 mm in cavities in baryte with calcite and ankerite, collected from the top of the Great Limestone (Minrec 31.3.248).
