Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite.

Geologists use the term "marble" to refer to metamorphosed limestone; however stonemasons use the term more broadly to encompass unmetamorphosed limestone.[1]

Marble is commonly used for sculpture and as a building material.

Etymology

The word "marble" derives from the Greek "μάρμαρον" (mármaron),[2] from "μάρμαρος" (mármaros), "crystalline rock", "shining stone",[3][4] perhaps from the verb "μαρμαίρω" (marmaírō), "to flash, sparkle, gleam".[5] This stem is also the basis for the English word marmoreal, meaning "marble-like."

Whilst the English term resembles the French marbre, most other European languages (e.g. Spanish mármol, Italian marmo, Portuguese mármore, German and Swedish marmor, Dutch marmer, Polish marmur, Czech mramor and Russian мрáмор ) follow the original Greek.

Physical Origins

Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, (most commonly limestone or dolomite rock). Metamorphism causes variable recrystallization of the original carbonate mineral grains.
