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. 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 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. Magnesian limestone is an obsolete and poorly-defined term used variously for dolomite, limestone containing

How Does Limestone Affect the Environment?

Apr 09, 2020· Limestone mining can pollute water and create sinkholes. When limestone dissolves while it's still in the ground, caves and gullies form, a natural phenomenon known as karst. Although this doesn't hurt the environment in its natural form, once the limestone is mined out, sinkholes can form and disrupt underground waterways.

Limestone (Industrial) Refer also Dolomite (Industrial)

The flat-lying fossiliferous limestone unit is approximately 30 m thick. Overburden comprises 3–4 m of calcrete, the lower 2 m of which is high in clay, which also infills solution cavities and pipes extending up to 20 m below the surface. The limestone is extracted by ripping and dozing, although some blasting of hard bands is required.
