structural:summarization
Marble is a metamorphic rock consisting of carbonate minerals (most commonly calcite (CaCO) or dolomite (CaMg(CO)) that have recrystallized under the influence of heat and pressure. It has a crystalline texture, and is typically not foliated (layered), although there are exceptions.

In geology, the term marble refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material.
