calcaire

Also known as Kalkstein

roche sédimentaire

AI overview

Limestone is a sedimentary rock made mostly of calcium carbonate minerals that forms when calcium precipitates out of water, often through the accumulation of sea creatures like corals and shells. It's the main source of lime and frequently contains fossils that help scientists understand Earth's past.

Les calcaires sont des roches sédimentaires, tout comme les grès ou les gypses, facilement solubles dans l'eau (voir karst), composées majoritairement de carbonate de calcium CaCO3, mais aussi de carbonate de magnésium MgCO3. Ces roches carbonatées ont une grande importance du point de vue géologique et économique.
