OverviewDescriptionClassificationFormationLimestone landscapeUsesDegradation by organismsSee also

Like most other sedimentary rocks, most limestone is composed of grains. Most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera. These organisms secrete shells made of aragonite or calcite, and leave these shells behind when they die. Other carbonate grains composing limestones are ooids, peloids, intraclasts, and extraclasts. Limestone often contains variable amounts of silica in the form of chert (chalcedony, flint, jasper, etc.) or si

What is the limestone's mining process? Quora

Limestone deposits are found throughout the world. They are “mined” in a process known as “quarrying.” This process varies depending on the use of the product. If it is to be made into cement, it is needed in small pieces so that it can be ground

Limestone: Rock Uses, Formation, Composition, Pictures

FormationGeologyCompositionPropertiesNamesUsesAdvantagesOther usesAvailabilityLimestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite. It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal, and fecal debris. It can also be a chemical sedimentary rock formed by the precipitation of calcium carbonate from lake or ocean water. Most limestones form in shallow, calm, warm marine waters. That type of environment is where organis

How is limestone formed? What is limestone? Limestone

OrganicChemical LimestonesDetrital Limestonesfrom Sediment to RockThe sediment that goes to make up limestone may have been derived from the dead remains of marine organisms such as: 1. bryozoa 2. corals 3. crinoids 4. microscopic algae 5. shells These organisms remove calcium carbonate (CaCO3) from the sea water to construct shells or skeletons. CaCo3 cement, which may be fine grained (called micrite) or coarse grained (called sparite), holds the fossils (such as coccoliths and foraminifera) together to form a limestone.
