limestone Characteristics, Uses, & Facts Britannica

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 fascinated earth scientists because of its rich fossil

Limestone Wikipedia

Limestone is a type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.In old USGS publications, dolomite was referred to as magnesian limestone, a term now reserved for magnesium

2.5 Most of the calcite precipitated by marine organisms contains a certain percentage of magnesium. Such calcite is called magnesian calcite; it’s subdivided into low-magnesium calcite and high-magnesium calcite at 4% MgCO3 content. Generally the more advanced the organism, the less magnesium in the calcite.In the case of red algae, an important sediment producer, the
