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.
