Strontium minerals

strontium sulfate mineral

Strontianite (SrCO3) is an important raw material for the extraction of strontium. It is a rare carbonate mineral and one of only a few strontium minerals. It is a member of the aragonite group.

Acuminite is a rare halide mineral with chemical formula: SrAlF4(OH)·(H2O). Its name comes from the Latin word acumen, meaning "spear point". Its Mohs scale rating is 3.5.

thumb|Putnisite (animation) Putnisite is a mineral composed of strontium, calcium, chromium, sulfur, carbon, oxygen and hydrogen. It was discovered on the Polar Bear Peninsula in Shire of Dundas, Western Australia in 2007 during mining activity. Following identification and recognition by the IMA in 2012 the mineral was named after mineralogists Andrew and Christine Putnis. The formal description was published in 2014.

Svanbergite is a colorless, yellow or reddish mineral with the chemical formula SrAl3(PO4)(SO4)(OH)6. It has rhombohedral crystals.

Weloganite is a rare carbonate mineral with the formula: It was discovered by Canadian government mineralogist Ann P. Sabina in 1967 and named for Canadian geologist Sir William Edmond Logan (1798–1875). It was first discovered in Francon Quarry, Montreal, Quebec, Canada and has only been reported from a few localities worldwide.

Tausonite is the rare naturally occurring mineral form of strontium titanate: chemical formula: SrTiO3. It occurs as red to orange brown cubic crystals and crystal masses.

Yuksporite is a rare inosilicate mineral with double width, unbranched chains, and the complicated chemical formula . It contains the relatively rare elements strontium, titanium and niobium, as well as the commoner metallic elements potassium, calcium, sodium and manganese. As with all silicates, it contains groups of linked silicon and oxygen atoms, as well as some associated water molecules.

Cleusonite is a member of the crichtonite group of minerals with the chemical formula . This group of minerals contains approximately thirteen complex metal titanates. The structures of minerals of this group is complicated by frequent fine-scale twinning and metamictization due to radioactive elements. The crichtonite group consists of members of related mineral species of the type A{BC2D6E12}O38 which are characterized by their predominant cations (as seen in crichtonite (Sr), senaite (Pb), davidite (REE + U), landauite (Na), loveringite (Ca), lindsleyite (Ba), and mathiasite (K).

Belovite-(Ce) () is the cerium analogue of belovite-(La). It is a member in the belovite group being a subgroup of the apatite group.

Veatchite is an unusual strontium borate, with the chemical formula Sr2B11O16(OH)5·H2O. There are two known polytypes, veatchite-A and veatchite-p.

Khomyakovite is an exceedingly rare mineral of the eudialyte group, with formula . The original formula was extended to show the presence of both the cyclic silicate groups and M4-site silicon, according to the nomenclature of the eudialyte group. Some niobium substitutes for tungsten in khomyakovite. Khomyakovite is an iron-analogue of manganokhomyakovite, the second mineral being a bit more common. The two minerals are the only group representatives, beside taseqite, with species-defining strontium, although many other members display strontium diadochy. Khomyakovite is the third eudialyte-g

Fluorcaphite is a mineral with the chemical formula . It is found in the Kola Peninsula in Russia. Its crystals are hexagonal (dipyramidal class) and are transparent with a vitreous luster. It is light to bright yellow, leaves a white streak and is rated five on the Mohs Scale. Fluorcaphite is radioactive.

Ancylite is a group of hydrous strontium carbonate minerals containing cerium, lanthanum and minor amounts of other rare-earth elements. The chemical formula is with ancylite-Ce enriched in cerium and ancylite-La in lanthanum.

Taikanite is a silicate mineral. It was named after the Taikan Range, Russia, its type locality.

Belovite-(La) () is the lanthanum analogue of belovite-(Ce). It is a member in the belovite group being a subgroup of the apatite group.

Lulzacite is a strontium-containing phosphate mineral with the chemical formula Sr2Fe2+(Fe2+,Mg)2Al4(PO4)4(OH)10.

Manganokhomyakovite is a very rare mineral of the eudialyte group, with the chemical formula . This formula is in extended form (based on the original one), to show the presence of cyclic silicate groups and domination of silicon at the M4 site, basing on the nomenclature of the eudialyte group. Some niobium substitutes for tungsten in khomyakovite. As suggested by its name, manganokhomyakovite is a manganese-analogue of khomyakovite, the latter being more rare. The two minerals are the only group representatives, beside taseqite, with species-defining strontium, although many other members di

Fontarnauite is a relatively recently described, rare sulfate, borate mineral with the chemical formula . It is found in an evaporite boron deposit. It coexists with other evaporite boron minerals, especially probertite. It is monoclinic, crystallizing in the space group P21/c.

Strontiomelane is an oxide mineral from the coronadite group in the hollandite supergroup. Specimens of the mineral appear very similar to other manganese oxides from the same group, such as the Ba-analogue hollandite. The type locality is the Praborna mine in Saint-Marcel, Italy.

Alsakharovite-Zn (IMA symbol: Ask-Zn) is an extremely rare alkaline strontium zinc titanium silicate mineral from the cyclosilicates class, with the chemical formula , from alkaline pegmatites. It belongs to the labuntsovite group.
