Limestone is a common type of carbonate sedimentary rock which is the main source of the material lime.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes ...

Carboniferous rocks in Europe and eastern North America largely consist of a repeated sequence of limestone,sandstone,shale and coal beds.[21]In North America, the early Carboniferous is largely marine limestone, which accounts for the division of the Carboniferous into two periods in North American schemes.
