Marble is a non foliated metamorphic rock resulting from the metamorphism of limestone, composed mostly of calcite (a crystalline form of calcium carbonate, CaCO3). It is extensively used for sculpture, as a building material, and in many other applications.
The word "marble" derives from the Ancient Greek μάρμαρον (mármaron) or μάρμαρος (mármaros), "crystalline rock", "shining stone", perhaps from the verb μαρμαίρω (marmaírō), "to flash, sparkle...

Marble is a non foliated metamorphic rock resulting from the metamorphism of limestone, composed mostly of calcite (a crystalline form of calcium carbonate, CaCO3). It is extensively used for sculpture, as a building material, and in many other applications.
The word "marble" derives from the Ancient Greek μάρμαρον (mármaron) or μάρμαρος (mármaros), "crystalline rock", "shining stone", perhaps from the verb μαρμαίρω (marmaírō), "to flash, sparkle, gleam". This stem is also the basis for the English word marmoreal, meaning "marble-like."
Marble is a metamorphic rock resulting from regional or, rarely, contact metamorphism of sedimentary carbonate rocks (either limestone or dolomite rock) or metamorphism of older marble. This metamorphic process causes a complete recrystallization of the original rock into an interlocking mosaic of calcite, aragonite and/or dolomite crystals. The temperatures and pressures necessary to form marble usually destroy any fossils and sedimentary textures...
