One of the present authors (PT) observed an open fracture containing well-crystallized dawsonite with strontianite and calcite.
Mineralization in the limestone formations exposed in the Francon quarry is limited to occasional small cavities, veins and solid pods containing common minerals such as calcite, dolomite, strontianite, barite, quartz, pyrite and marcasite.
In the Hilairitovoye pegmatite, holotype material is associated with: microcline, albite, calcite, nenadkevichite, hilairite, catapleiite, strontianite
, donnayite-(Y), synchysite-(Ce), pyrite, etc.; in a pectolite-aegirine-microcline vein other associated minerals are: natrolite, calcite, neodymian ewaldite, etc.
(1933) The occurrence of strontianite
at Sierra Mojada, Mexico.
Strontianite is rare in the north Pennines (see Young, 1985b).
This has been complemented by the discovery of a suite of primary minerals which are uncommon in the Mississippi Valley type deposits of the north Pennines including bournonite, millerite, strontianite, ullmannite, and (perhaps) hydromagnesite.
Associated minerals are: calcite, dolomite, strontianite
, ewaldite, minerals of the serpentine and apatite groups, pyrrhotite, pyrite, chalcopyrite, sphalerite, and pyrochlore.
Naturally it's easy for anyone to enjoy simply looking at case after case of phenomenal fluorite, calcite, galena, sphalerite, witherite, strontianite
While it works with highly reactive species such as calcite and strontianite, it is less effective for slowly dissolving carbonates.
A group of us speculated as to whether the unknown was one species or another; suggestions included leifite, nenadkevichite, apatite, dawsonite, natrolite, phillipsite, strontianite, and aragonite.

This orebody provided some of the most spectacular specimens ever found in the district: worldclass examples of fluorite, witherite, benstonite, strontianite
