Calcite Marble Metamorphic Rock

It is a metamorphosed carbonate rock limestone or dolomite rock.

Calcite marble metamorphic rock.

Marble is typically not foliated although there are exceptions. Calcite is the principal constituent of limestone and marble. Black marble also occurs. Some geologists consider it to be a ubiquitous mineral one that is found everywhere.

Marble is a metamorphic stone formed by subjecting limestone to heat or pressure. Marble is a metamorphic rock consisting predominantly of calcite or dolomite. Marble is a sparkling and typically granoblastic rock. These rocks are extremely common and make up a significant portion of earth s crust.

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 a mass of interlocking calcite crystals. Calcite is a rock forming mineral with a chemical formula of caco 3. Granoblastic rocks have uniformly sized equidimensional anhedral grains produced by recrystallization in a solid state metamorphism.

In geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Calcite specimens can occur in metamorphic deposits igneous rocks and hydrothermal veins. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Calcite is the principal constituent of limestone and marble.

Marble takes a high polish. It is extremely common and found throughout the world in sedimentary metamorphic and igneous rocks. These rocks are extremely common and make up a significant portion of earth s crust. Some geologists consider it to be a ubiquitous mineral one that is found everywhere.
