Physical properties
Hardness of 3 on Mohs scale, typically gray or brown, dull to earthy luster, composed mainly of calcite and fossil fragments with no notable cleavage.
Formation & geological history
Formed through the accumulation and compaction of organic carbonate debris and shells in shallow marine environments over millions of years.
Uses & applications
Widely used in construction, cement production, dimension stone, and as a raw material in agriculture and industry.
Geological facts
Limestone formations often preserve ancient marine life and can make up massive geological structures like the White Cliffs of Dover.
Field identification & locations
Easily identified by its effervescence when exposed to dilute hydrochloric acid; found globally in regions with ancient shallow seas.
