Limestone: The Calcium Carbonate Chemical Sedimentary Rock

DefinitionGeologyFormationCostUsesOther usesFutureAdvantagesIssuesResourcesIndustryMission\"Limestone\" means any rock formed mostly of calcium carbonate (CaCO3), but to geologists, limestone is only one of several types of \"carbonate rocks.\" These rocks are composed of more than 50% carbonate minerals, generally the minerals calcite (pure CaCO3) or dolomite (calcium-magnesium carbonate, CaMg[CO3]2) or both.See more on geology

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 siget price

What is Calcium Carbonate? Industrial Minerals

As limestone, calcium carbonate is a biogenic rock, and is more compacted than chalk. As marble, calcium carbonate is a coarse-crystalline, metamorphic rock, which is formed when chalk or limestone is recrystallised under conditions of high temperature and pressure.get price

Lime (material) Wikipedia

OverviewProductionCycleBuilding materialsLime is a calcium-containing inorganic mineral composed primarily of oxides, and hydroxide, usually calcium oxide and/ or calcium hydroxide. It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The word lime originates with its earliest use as building mortar and has the sense of sticking or adhering. These materials are still used in large quantities as building and engineering materials, as chemical feedstocks
