limestone classification

Limestone classification is based on its mineral content, texture, and appearance. It mainly consists of calcium carbonate from organic sources like shells or coral, but can vary in impurities. Common types include fossiliferous limestone with fossils, crystalline limestone with coarse crystals, and oolitic limestone made of small, rounded grains. Some limestones are chalky, soft, or dense and hard. These differences help determine their uses in construction, industry, or sculpture. Essentially, limestone classification reflects its mineral makeup and structure, guiding its suitability for various applications.
