Apr 14, 2022 · Geology. Limestone is a common sedimentary rock that is composed mostly of the mineral calcite (CaCO3). It is produced by crystallization from water, or by accumulation of shells and shell fragments. Limestone, a sedimentary rock, is made up mainly of calcite, which is made up mainly of the skeletons of microsopic organisms. Limestone is a sedimentary rock made almost entirely of fossils. Fossils are the remains of ancient plants and animals, like an imprint in a rock or actual bones and shells that have turned into rock. Fossils are found in sedimentary rocks and hold the clues to life on Earth long ago. Limestone: You humans would know so little without rocks ...

Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth’s sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.Limestone has proven its use from simple treads and pavers to landscaping structures and bridges, to soaring cathedrals over and over again. One benefit that has made limestone a choice product is the consistency of deposit.
