Physical properties

Hardness: 3 on Mohs scale. Color: Light tan or beige. Luster: Dull to earthy. Structure: Fine-grained with visible fossil fragments.

Formation & geological history

Formed through the accumulation and compaction of organic carbonate debris in shallow marine environments over millions of years.

Uses & applications

Used in construction, cement production, agriculture, and as a natural source for studying ancient marine life and fossils.

Geological facts

Limestone often preserves ancient sea creatures like brachiopods and crinoids, providing key insights into prehistoric marine ecosystems.

Field identification & locations

Readily reacts with dilute hydrochloric acid, producing visible effervescence due to its calcium carbonate composition.
