How do you recognize limestone and marble?
How do you recognize limestone and marble? The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock. Limestone forms when shells, sand, and mud are deposited at the bottom of oceans and lakes and over time solidify into rock.

Limestone
Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth’s sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.

Limestone Formation | Science project | Education.com
Limestone is composed of tiny shells that fell to the ocean’s floor when sea creatures died. The pressure from other shells, the water and sand washing over them squashes the tiny shells together into rock. When the pressure continues, it can turn into marble.

Calcination of Limestone
Larger voids allow easy passage for CO2 gases during calcination and it results in a reduction of volume during calcination. Some limestone, due to its crystalline structure, disintegrates during the calcination process. This type of limestone is not useful for calcining. There is some other limestone whose behaviour is the opposite.
