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.
1933) The occurrence of strontianite
at Sierra Mojada, Mexico.
3 mm microcrystal; alphine assemblage Kaolinite Locality 5; cream-white micaceous crystal aggregates to 1 mm Malachite Locality 9, Redwood; green film staining calcite Strontianite
General occurrence Sulfur Locality 5; subhedral microcrystals to 0.
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.
The strontianite occurrence on the West High Cross vein is in a similar transitional position.
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.
Carbonates Ancylite-(Ce) Ancylite-(La) Aragonite Bastnasite-(Ce) Calcite Cerussite Cordylite-(Ce) Dawsonite Dolomite Donnayite-(Y) Kukharenkoite-(Ce) Rhodochrosite Siderite Strontianite
This orebody provided some of the most spectacular specimens ever found in the district: worldclass examples of fluorite, witherite, benstonite, strontianite
In two of the areas, strontianite
was included into colemanite with active alteration of the exposed strontianite
