It is found naturally in the minerals celestite and strontianite.
Formerly, strontianite was also mined and used as a whitener for the sugar industry.
It occurs in nature as the mineral strontianite.
Various materials have been mined here including lead, and strontianite, which contains the element named after the village, Strontium.
Strontianite occurs in several different habits.
Synthetic barium chlorapatite, strontianite, and fluorapatite were used as standards for the elements they contain.
Associated minerals include strontianite, dawsonite and calcite.
In 1791-2 Hope discovered the chemical element strontium and named it after Strontian, the west highland village where he found strontianite.
Strontianite: Strontian, Scotland (also the element strontium derived from the mineral)
In strontianite repeated twinning forms cyclic twins with three or four individuals, or polysynthetic twins.
Strontium was first discovered at the type locality, Strontian, in western Scotland in strontianite associated with baryte.
The mining of strontianite in Germany ended when mining of the celestite deposits in Gloucestershire started.

In the Gulf coast of Louisiana and Texas, strontianite occurs with celestine in calcite cap rock of salt domes.
Some authors credit Cruickshank with first suspecting an unknown substance in a Scottish mineral, strontianite, found near Strontian, in Argyleshire.
Because of its extreme reactivity with oxygen and water, this element occurs naturally only in compounds with other elements, such as in the minerals strontianite and celestite.
It occurs in association with alstonite, barite, barytocalcite, calcite, daqingshanite, fluorite, huntite, monazite, phlogopite, pyrite, sphalerite, strontianite, and quartz.
Because strontium is used most often in the carbonate form, strontianite would be the more useful of the two common minerals, but few deposits have been discovered that are suitable for development.
The direction perpendicular to the plane containing the two optic axes is called the optical direction Y. In strontianite Y is parallel to the b crystal axis.
He named the mineral strontianite (strontium carbonate) and made clear that it was distinct from the witherite (barium carbonate) and stated that it contained a new element.
Both strontium and strontianite are named after Strontian, a village in Scotland near which the mineral was first discovered in 1790 by Adair Crawford and William Cruickshank.
The strontium hydroxide was recycled in the process, but the demand to substitute losses during production was high enough to create a significant demand initiating mining of strontianite in the Münsterland.
In the hills to the north of Strontian lead was mined in the 18th century and in these mines the mineral strontianite was discovered, from which the element strontium was first isolated.
The physician and mineral collector Friedrich Gabriel Sulzer analysed together with Johann Friedrich Blumenbach the mineral from Strontian and named it strontianite.
