Calcite Marble Metamorphic Rock

Under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals.

Calcite marble metamorphic rock.

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. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. These rocks are extremely common and make up a significant portion of earth s crust.

Calcite is the principal constituent of limestone and marble. Calcite specimens can occur in metamorphic deposits igneous rocks and hydrothermal veins. Granoblastic rocks have uniformly sized equidimensional anhedral grains produced by recrystallization in a solid state metamorphism. Calcite is the principal constituent of limestone and marble.

Some geologists consider it to be a ubiquitous mineral one that is found everywhere. Marble is a sparkling and typically granoblastic rock. 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. Calcite is a rock forming mineral with a chemical formula of caco 3.

Marble takes a high polish. Marble is a metamorphic rock consisting predominantly of calcite or dolomite. Impurities produce pale gray brown or variegated colored rock. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite.

Black marble also occurs. Marble is a metamorphic stone formed by subjecting limestone to heat or pressure. In pure form marble consists of calcium carbonate calcite and is sparkling white. Some geologists consider it to be a ubiquitous mineral one that is found everywhere.
