Anton von Swab
Formula:
Ca5(AsO4)3F
System:
Hexagonal
Colour:
Colorless, light yellow, ...
Lustre:
Sub-Vitreous, Resinous, Greasy
Hardness:
5
Name:
Named in 1891 by (Sten Anders) Hjalmar Sjögren in honor of Anton von Swab (Svab) [July 29, 1703 Fahlun, Sweden - January 28, 1768 Stockholm, Sweden], chemist, mineralogist, and Swedish mining official - Bergmästaregatan in Skåne and Kronoberg. Swab was a step-brother of Emmanuel Swedenborg. Swab made important discoveries. He refined zinc from calamine and later from blende and together with Axel Cronstedt developed a commercial process for refining zinc and in turn greatly aided the manufacture of brass in Sweden. Swab also discovered native antimony at Sala, Sweden. Weeks (1960) cited an obituary of Anton von Swab and Georg Brandt written by Carl von Linne: "The kingdom and our sciences have now lost in a single year two stars of the first magnitude, Brandt and Svab. The Bureau of Mines and the science of mining have lost their supporting pillars. Men such as these never spring up like mushrooms. So far as I know, Europe has none like them. ... A king can lose an army, but within a year have another ]ust as good. A king can lose a fleet and within two years have another rigged up, but a Brandt and a Svab cannot be gotten again during his entire reign"

Isostructural with:
Apatite Supergroup. The arsenate analogue of fluorapatite.

Forms a series toward fluorapatite with an increase of P for As. Also forms a series toward hedyphane and mimetite with an increase of Pb and Cl. Occurs as an rare accessory mineral in calc-silicate skarns.

Sjögren (1891) described and named svabite as a new mineral from Harstigen, Värmland, Sweden. In 1892 he reported the occurrence of svabite at Harstigen and also at another locality, the Jakobsberg Mine, Sweden. At the time they did not distinguish between OH-dominant and F-dominant calcium arsenate. A re-examination of the chemical analyses of Sjögren (1891, 1892) shows that the mineral from Harstigen was probably not svabite (F-dominant), but johnbaumite (OH-dominant). The reason for "probably" concerns the inaccuracy of fluorine determinations in the time period. The Sjögren (1891, 1892) chemical analysis of the specimen from Jakobsberg is F-dominant (svabite). The accuracy of the analysis of the Harstigen specimen relating to its being the type locality for svabite, has been questioned (Biagioni & Pasero 2013) and Jakobsberg may be regarded as the type locality.
