Calcite Marble Metamorphic Rock

In pure form marble consists of calcium carbonate calcite and is sparkling white.

Calcite marble metamorphic rock.

Calcite is the principal constituent of limestone and marble. Calcite is the principal constituent of limestone and marble. 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. Marble is a metamorphic stone formed by subjecting limestone to heat or pressure.

In geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Black marble also occurs. Marble is a metamorphic rock consisting predominantly of calcite or dolomite. These rocks are extremely common and make up a significant portion of earth s crust.

Marble is typically not foliated although there are exceptions. It is a metamorphosed carbonate rock limestone or dolomite rock. Marble is a sparkling and typically granoblastic rock. Some geologists consider it to be a ubiquitous mineral one that is found everywhere.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Impurities produce pale gray brown or variegated colored rock. It is extremely common and found throughout the world in sedimentary metamorphic and igneous rocks. Under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals.

Some geologists consider it to be a ubiquitous mineral one that is found everywhere. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite. Granoblastic rocks have uniformly sized equidimensional anhedral grains produced by recrystallization in a solid state metamorphism. Marble takes a high polish.
