Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being limesecreting 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 fascinated earth scientists because of its rich fossil ...
Lime is a mineral made by heating limestone or dolomite in a kiln. Lime is used in a variety of chemical industries, in sugar processing plants, in steel mills, sewage treatment plants, and at paper mills. "Burned" or kilned limestone was also used as plaster and mortar in the homes of early settlers, and even into the mid20th century.
