Chemical Composition Of Granite And Marble

Typically marble is composed of the following major constituents.

Chemical composition of granite and marble.

A granite containing both muscovite and biotite micas is called a binary or two mica granite. Two mica granites are typically high in potassium and low in plagioclase and are usually s type granites or a type granites. A worldwide average of the chemical composition of granite by weight percent based on 2485 analyses. Zircon and apatite mainly as inclusions in biotite titanite orthite magnetite pyrite.

Granite s durability and decorative appearance make it a popular building material in homes and buildings. 5 poor fire resistance. The chief chemical composition of granite is sio 2 hence it is acid resistant. The quartz in the granite will have crystalline transition in 573 c and cubical dilatation in 870 c.

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. Though a very common rock granite is far from ordinary. It is also attractive in the trade of ornamental rocks because depending on the chemical composition of the marble can have.

Marble is also widely used in construction. Hence the granite will break when fire takes place. Marble is commonly used for sculpture and as a building material. A variety of materials may be used to make countertops including artificial materials quartz marble slate and granite.
