Marble is a metamorphic(characterized by change of form) limestone. When the limestone is heated and pressure is put on it, the calcite(CaCO3) in it melts. If the limestone was pure before heat or pressure was applied to it, a white marble will be obtained. If it had hematite or haematite(iron oxide, Fe2O3) or clay in it, reddish marble will be obtained.

Limestone is called limestone because it has lime in it from the sea water it if formed in.


Quicklime is calcium oxide - CaO and slaked lime is calcium hydroxide - Ca(OH)2. CaCO3--------------CaO + CO2 This reaction occur at high temperature; mixing calcium oxide with water, the hydroxide is obtained.


The chemical reation is:CaCO3 = CaO + CO2So, theoretically 840,4 kg CaO are obtained.

dolomitic limestone is different from agricultural or hydrated limestone the difference is in the MgO content and hardness Dolomitic Limestone is harder than both and its MgO content is higher. The CaO is lower in Dolomitic limestone and High in the later.

Limestone comes from the crust. Limestone is a sedimentary rock.


Limestone is chemical; though in certain cases, limestone may be organic, when it is composed of the dead remains of organisms (fossils). That's called fossiliferous limestone, or fossil-rich limestone, but regular limestone is just chemical.
