Properties of Marble
Marble is a type of metamorphic rock that forms from the transformation of limestone under high heat and pressure. It is characterized by its distinctive, often beautiful, veined, or mottled appearance, and it is commonly used in construction, sculpture, and architecture due to its aesthetic appeal and durability.
The following table provides a list of marble properties in both SI and US customary/Imperial units at normal temperature and pressure (NTP).
