Marble Stones
Name and Composition - Calcitic marble: Calcitie (CaCO3) and Dolomite marble: Dolomite [Ca, Mg (CO3)2] with other impurities like iron oxide, silica etc.
Physical Properties - Marble is metamorphic rock, fine to coarse grained, white to off white with varying colours and shades. Grains are often recrystallized and closely interlocked, hence has low porosity.
Mode of Occurrence - Generally occurs as sedimentary and metamorphic deposits from arrivals to tertiary formations.
Uses - Used as dimensional and decorative stone in building for flooring, wall cladding, pillars, handicrafts, monuments, tombs, temples etc. by virtue of carving and sculpture.
Mineral based Industries – Dimond gangue saws, cutting and polishing units, handicrafts and artisan units like carving and sculpturing.
Industrial Prospects – Gangue saws units, cutting and polishing units, carving, artisan work etc.
