barite
barite (baryte) A
mineral, BaSO
4, which may form a
solid solution series with
celestite (SrSO
4); sp. gr. 4.3–4.6;
hardness 3.0–3.5;
orthorhombic; colourless to white, often tinged yellow, brown, blue, green, and red; white
streak;
vitreous lustre;
crystals commonly
tabular,
prismatic, but can be fibrous, lamellar, and often granular;
cleavage perfect {001}, present {210}, {010}. Occurs as a vein filling, as a
gangue mineral with ores of lead, copper, zinc, silver, iron, and nickel, associated with
calcite,
quartz,
fluorite,
dolomite, and
siderite, and as a low-temperature mineral which also occurs as a replacement for
limestone, and as a
cement in
sandstone. Insoluble in acid. It is used as a weighting agent in drilling muds, in the chemical industry, in the manufacture of rubber, paper, and high-quality paints, and as an X-ray absorbent.
