What is limestone rock.

Basically, chert is a petrified limestone rock where the calcium carbonate is displaced with silicon dioxide. The limestone rocks found in the Ozarks formed in a shallow tropical sea much like we have in the Caribbean today. Most of the Ozarkian chert deposits are in Mississippian-age deposits, from about 325 to 360 million years ago.sedimentary rock such as limestone and sandstone. In the glaciated regions of NW and NE PA, aggregate is often mined glacial till, or pit-run gravel. In general, limestone is the hardest of the rocks, with shale being the softest, while pit-run varies widely in its usefulness as a road aggregate.Limestone is commonly defined as a rock composed of calcium carbonate (CaCO3) however, most limestone rocks contain significant amounts of magnesium ...Marl. Scala dei Turchi coastal marl formation, southern Sicily. Marl is an earthy material rich in carbonate minerals, clays, and silt. When hardened into rock, this becomes marlstone.
