STRONTIANITE , a See also:mineral consisting of See also:strontium carbonate, SrCO3. It takes its name from Strontian in See also:Argyllshire, where it appears to have been known as far back as 1764, but it was not recognized as a distinct mineral until later, when the examination of it led to the See also:discovery of the See also:element strontium. It crystallizes in the orthorhombic See also:system and is isomorphous with See also:aragonite and See also:witherite. Distinctly See also:developed crystals are, however, of rare occurrence; they are usually acicular with acute See also:pyramid-planes and are repeatedly twinned on the See also:prism. Radiating, fibrous or granular aggregates are more See also:common. The See also:colour is See also:- WHITE

brown. The hardness is 31 and the specific gravity 3.7. Strontium is sometimes partly replaced by an See also:equivalent amount of See also:calcium. The mineral occurs in metalliferous See also:veins in the See also:lead mines of Strontian in Argyllshire, Pateley See also:Bridge in See also:Yorkshire, Braunsdorf near See also:Freiberg in See also:Saxony; abundantly in veins in calcareous See also:marl near See also:Munster and See also:Hamm in See also:Westphalia; and in See also:limestone at Schoharie in New See also:York. It is used for producing red See also:fire in pyrotechny and for refining See also:sugar. (L. J.
