Marble is a metamorphic rock consisting of carbonate minerals (most commonly calcite (CaCO 3) or dolomite (CaMg(CO 3) 2) that have recrystallized under the influence of heat and pressure. [1] It has a crystalline texture, and is typically not foliated , although there are exceptions.
The advantage of this approach is low storage cost, unlimited texture resolution and easy texture mapping. [2] These kinds of textures are often used to model surface or volumetric representations of natural elements such as wood, marble, granite, metal, stone, and others.
Lorenzo Bartolini, (Italian, 1777–1850), La Table aux Amours (The Demidoff Table), Metropolitan Museum of Art, New York City, Marble sculpture. Marble has been the preferred material for stone monumental sculpture since ancient times, with several advantages over its more common geological "parent" limestone, in particular the ability to absorb light a small distance into the surface before ...
Marbleizing or faux marbling is used to make walls and furniture look like real marble. This can be done using either plaster or glaze techniques. Fresco is a simple technique, uses mixtures of tint and joint compound to add mottled color and subtle texture to plain walls,
During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. [1] The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. [2]
Granoblastic is an adjective describing an anhedral phaneritic equi-granular metamorphic rock texture. Granoblastic texture is typical of quartzite, marble, charnockites and other non-foliated metamorphic rocks without porphyroblasts. Characteristics defining granoblastic texture include: grains visible to the unaided eye, sutured boundaries ...

Carrara marble, or Luna marble (marmor lunense) to the Romans, is a type of white or blue-grey marble popular for use in sculpture and building decor. It has been quarried since Roman times in the mountains just outside the city of Carrara in the province of Massa and Carrara in the Lunigiana , the northernmost tip of modern-day Tuscany , Italy.
