Some of the key chemical properties of limestone include: Composition: Limestone is primarily composed of calcium carbonate (CaCO3), which typically makes up more than 95% of its chemical composition. Other minerals and compounds may also be present in smaller amounts, such as magnesium carbonate (dolomite), clay minerals, silica, iron …

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 has long …
