Marble as a rock. Marble is commonly used for sculpture and as a building material. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. Marble granular limestone or dolomite i e rock composed of calcium magnesium carbonate that has been recrystallized under the influence of heat pressure and aqueous solutions. The stone we call marble is a metamorphic rock mostly composed of calcite a type of calcium carbonate formed as a result of changes brought about in the structure of sedimentary or igneous rocks by extreme pressure or heat.

Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques. Characteristics of marble as a sculptural material. Marble is a granular metamorphic rock it is derived from limestone or dolomite and it consists of a mass of interlocking grains of calcite or the mineral dolomite. Form of it when limestone buried deep in the older layers of earth s crust is subjected to heat and pressure from thick layers of overlying sediments.

Petrographically marbles are massive rather than thin layered and consist of a.
