Oct 13, 2020Limestone is a sedimentary rock that is dominantly composed of the calcium-bearing carbonate minerals calcite and dolomite. Calcite is chemically calcium carbonate (formula CaCO 3 ). Dolomite is chemically calcium-magnesium carbonate (formula CaMg (CO 3) 2 ). Economic Importance Fossiliferous Limestone.

Low-MgO rocks are rich in quartz, calcite, or hematite. The same is largely true for Fe2O3(T). High-Fe2O3 meteorwrongs are iron ores, often hematite concretions. The ratio of magnesium to iron does not vary greatly among most kinds of stony meteorites. Rocks with MgO/Fe2O3(T) <0.2 or >6 are probably not meteorites.

Limestone. More than 50 percent of the surface rocks in Kentucky are limestones. Limestone is chiefly composed of the mineral calcite (calcium carbonate), but may contain small amounts of clay, silt, chert, and dolomite. Most limestones are layered and contain fossils of shellfish and other animals that lived in shallow seas.

What is Limestone? "Limestone" means any rock formed mostly of calcium carbonate (CaCO 3 ), 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 CaCO 3 ) or dolomite (calcium-magnesium carbonate, CaMg[CO 3 2 ) or both.

Limestone is a sedimentary rock which contains two major types of minerals; calcite and aragonite. This is because it forms as a result of the deposition of skeletal fragments of marine organisms such as coral, forams and molluscs. Whereas, chalk is a form of limestone containing calcite as the major mineral; about 99%.
