Most of the world's production of strontium used to be consumed in the production of cathode-ray tube (CRT) displays. The glass contained strontium and barium oxide to block X-rays. Consuming 75% of production, the primary use for strontium was in glass for colour television cathode-ray tubes, [56] where it prevented X-ray emission.
Celestine (the IMA-accepted name) [6] or celestite [1] [7] [a] is a mineral consisting of strontium sulfate (Sr S O 4). The mineral is named for its occasional delicate blue color. Celestine and the carbonate mineral strontianite are the principal sources of the element strontium, commonly used in fireworks and in various metal alloys.
Strontianite (Sr C O 3) 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. Aragonite group members: [2] aragonite (CaCO 3), witherite (BaCO 3), strontianite (SrCO 3), cerussite (PbCO 3)

1926, around 1,500 mineral species were firmly established at that time, the Roebling mineral collection (nowadays at the National Museum of Natural History, Smithsonian Institution, Washington, DC) lacked less than 15 of those (Colonel Washington A. Roebling (1837–1926), founding member of the Mineralogical Society of America).
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 village name in Gaelic , Sròn an t-Sìthein , translates as the nose [i.e. 'point'] of the fairy hill , meaning a knoll or low round hill inhabited by the ...
For example, the Greek word asbestos (meaning 'inextinguishable', or 'unquenchable'), for the unusual mineral known today containing fibrous structure. [5] The ancient historians Strabo (63 BC–19 AD) and Pliny the Elder (23–79 AD) both wrote of asbestos, its qualities, and its origins, with the Hellenistic belief that it was of a type of ...
Mineral evolution is a recent hypothesis that provides historical context to mineralogy. It postulates that mineralogy on planets and moons becomes increasingly complex as a result of changes in the physical, chemical and biological environment.
