Overview of Marble

Marble is a metamorphic rock of carbonate origin, primarily derived from limestone or dolomite through regional or contact metamorphism. Its name comes from the Greek word for “shining
stone.”

Types of Marble

Pure Marble: Composed mainly of calcite, typically white.
Colored Marble: Colors arise due to mineral impurities like graphite (gray), hematite (red/pink), and limonite (yellow/cream).
Dolomitic Marble: Contains dolomite rather than calcite.
Commercial Marble: Includes true marble as well as polished serpentine and crystalline limestone.
Physical and Chemical Properties-Texture: Mostly interlocked calcite crystals, providing durability and
polishability.-Hardness: Ranges from 3 to 3.5 on the Mohs scale.-Porosity: Very low, making it resistant to water absorption.-Solubility: Varies based on climate; some marbles degrade faster in harsh
weather.-Strength: Influenced by mineral composition and grinding.

Applications Used in
architecture,
sculptures, flooring,
and construction.
Ground marble is used
in industries like paints,
plastics, and ceramics.
Extraction and Quarrying-Requires geological mapping and core drilling to assess quality.-Extraction is done using wire saws and drilling techniques.-Factors affecting extraction include stone uniformity, dip angle, and waste thickness.
