Marble as a rock.

Marble is commonly used for sculpture and as a building material. 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. It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. 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.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. 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. 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.

Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.
