== Occurrences ==

=== Type locality ===
The [[Type locality (geology)|type locality]] is [[Strontian]], North West Highlands ([[Argyllshire]]), [[Scotland]], UK.  The [[Type specimen (mineralogy)|type material]] occurred in [[Hydrothermal vein|veins]] in [[gneiss]].<ref name=Dana/>

Other UK localities include Brownley Hill Mine (Bloomsberry Horse Level), Nenthead, [[Alston Moor]] District, North Pennines, North and Western Region (Cumberland), Cumbria, England, associated with a suite of primary minerals ([[bournonite]], [[millerite]] and [[ullmannite]]) which are not common in other [[Carbonate hosted lead zinc ore deposits|Mississippi Valley-type deposits]].<ref name=MinRec41>The Mineralogical Record (2010)  41-1:62 supplement</ref>

=== Canada ===
The Francon quarry, [[Montréal]], Québec.  <br />
Strontianite is very common at the Francon Quarry, in a great variety of habits.  It is a late stage mineral, sometimes found as multiple generations.  It is found as translucent to opaque, white to pale yellow or beige generally smooth surfaced spheroids, hemispheres and compact spherical and botryoidal [[Aggregate (geology)|aggregate]]s to 10&nbsp;cm in diameter, and as spheres consisting of numerous radiating acicular crystals, up to 1&nbsp;cm across.  Also as tufts, parallel bundles, and sheaf-like clusters of fibrous to acicular crystals, and as white, finely granular porcelaneous and waxy globular aggregates.  Transparent, pale pink, columnar to tabular sixling twins up to 1&nbsp;cm in diameter have been found, and aggregates of stacked stellate sixling twins consisting of transparent, pale yellow tabular crystals.<ref name=MinRec37/>

Another Canadian occurrence is at [[Nepean, Ontario|Nepean]], Ontario, in vein deposits in [[limestone]].<ref name=Dana/>

=== Germany ===

It also occurs at [[Yukspor]] Mountain, Khibiny Massif, Kola Peninsula, Murmanskaja Oblast', Northern Region, in an [[aegerine]]-[[natrolite]]-[[microcline]] vein in [[foyaite]], associated with [[aegirine]], [[anatase]], [[ancylite-(Ce)]], [[barylite]], [[catapleiite]], [[cerite-(Ce)]], [[cerite-(La)]], [[chabazite-(Ca)]], [[edingtonite]], [[fluorapatite]], [[galena]], [[ilmenite]], [[microcline]], [[natrolite]], [[sphalerite]] and [[vanadinite]].<ref name=MinRec35A>The Mineralogical Record (2004) 35-2:176</ref>  At the same locality it was found in [[alkaline]] [[pegmatite]] veins associated with [[clinobarylite]], [[natrolite]], [[aegirine]], [[microcline]], [[catapleiite]], [[fluorapatite]], [[titanite]], [[fluorite]], [[galena]], [[sphalerite]], [[annite]], [[astrophyllite]], [[lorenzenite]], [[labuntsovite-Mn]], [[kuzmenkoite-Mn]], [[cerite-(Ce)]], [[edingtonite]], [[ilmenite]] and [[calcite]].<ref name=MinRec35B>The Mineralogical Record 35-4:347 (2004)</ref>

=== United States ===
In the [[Gulf coast]] of [[Louisiana]] and [[Texas]], strontianite occurs with [[Celestine (mineral)|celestine]] in [[calcite]] [[cap rock]] of [[salt domes]].<ref name=Dana/>

At the Minerva Number 1 Mine (Ozark-Mahoning Number 1 Mine) Ozark-Mahoning Group, [[Cave-in-Rock, Illinois]], in the Kentucky [[Fluorspar]] District, [[Hardin County, Kentucky|Hardin County]] strontanite occurs as white, brown or rarely pink tufts and bowties of acicular crystals with slightly curved terminations.<ref name=R&M85>Rocks & Minerals (2010) 85-3:212</ref>

In the [[Silurian]] [[Lockport (town), New York|Lockport]] Group, Central and Western [[New York (state)|New York]]  strontianite is observed in cavities in eastern Lockport, where it occurs as small white radiating sprays of acicular crystals.<ref name=R&M84>Rocks & Minerals (2009) 84-4:332</ref>

In [[Schoharie County]], New York, it occurs in [[geode]]s and [[Hydrothermal vein|veins]] with [[Celestine (mineral)|celestine]] and [[calcite]] in [[limestone]],<ref name=Dana/> and in [[Mifflin County]], Pennsylvania, it occurs with [[aragonite]], again in [[limestone]].<ref name=Dana/>
