How did limestone form
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 has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone.

Limestone, or its metamorphic cousin, marble, is rock made primarily of calcium carbonate. These rock types are often formed from the bodies of marine plants and animals, and their shells and skeletons can be preserved as fossils. Carbon locked up in limestone can be stored for millions—or even hundreds of millions—of years.Watch this video for a demonstration of the advantages of crushed limestone composite flooring over ceramic tile.
