Physical properties
Hardness 3 on Mohs scale, grayish-white to cream color, dull to earthy luster, massive crystal habit, reacts with dilute hydrochloric acid.
Formation & geological history
Formed through the accumulation and compaction of organic debris like shells, coral, and microfossils, or by chemical precipitation of calcium carbonate in shallow marine waters.
Uses & applications
Carved for statues, architectural features, building materials, dimension stone, and agricultural lime production.
Geological facts
Limestone statues are highly susceptible to weathering and acid rain over time, which causes dissolving and fine detail loss, as seen on this weathered garden sculpture.
Field identification & locations
Can be identified by its soft nature (scratched by a copper coin/steel knife), light color, effervescence with acid, and presence of fossil remnants or fine graining.
