Physical properties
Hardness of 3 on the Mohs scale, colors ranging from grey to yellowish-brown with white mineral veins, dull to earthy luster, cryptocrystalline or fine-grained structure, specific gravity around 2.7.
Formation & geological history
Formed through the accumulation and compaction of organic remains such as shells, coral, and algal debris in marine environments, often later fractured and healed by hydrothermal solutions depositing secondary calcite.
Uses & applications
Used primarily in construction, production of lime and cement, aggregate for roads, and occasionally in ornamental stonework.
Geological facts
Limestone makes up about 10% of the total volume of all sedimentary rocks on Earth and frequently contains fossils of ancient marine organisms.
Field identification & locations
Can be easily identified in the field by its effervescence (bubbling) when a drop of weak acid, such as vinegar, is applied due to the release of carbon dioxide.
