Is Marble stronger than limestone?

Is Marble stronger than limestone?

Marble and limestone lie at the opposite end of the hardness scale from granite. While marble is slightly harder and denser than limestone, both rate very low on the Mohs scale, a rating used to measure the hardness of stones. Limestone generally ranks at around a 3 on the scale, while marble falls between 3 and 4.

Is limestone and marble the same thing?

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.

Is limestone or marble more expensive?

Why limestone, marble and granite cost different prices Granite is very tough, making it harder to quarry and work. These factors influence the final price of the stone so although limestone is generally more affordable, a rare limestone that's travelled a long way may be more expensive than a local marble.

Does limestone become marble?

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.
