Carbonate, barium mineral
Specific gravity: 4.289 to 4.293
Hardness: 3 to 3½
Colour: colourless, white, pale yellow; colourless in transmitted light
Solubility: Readily soluble in hydrochloric acid; moderately soluble in sulphuric and nitric acids
Witherite occurs typically, along with baryte and other Ba-bearing minerals,
in epithermal (low temperature)
hydrothermal mineral veins, usually resulting from the alteration of baryte.
Other commonly associated mnerals
include calcite, sphalerite and
At Snailbeach mine, near Minsterley, Shropshire, England, UK, witherite occurs impregnated with hydrocarbon and overgrown by baryte (RES p271, 274).
