Marble Is Formed From

Marble is commonly used for sculpture and as a building material.

Marble is formed from.

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. The name marble comes from the greek word marmaros which means shining stone. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. Marble marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures.

Petrographically marbles are massive rather than thin layered and consist of a. The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. During metamorphism the calcite limestone recrystallizes forming the interlocking calcite crystals that make up the marble.

They go through different processes when formed. Marble is essentially a crystallized form of stone a metamorphic rock formed from other materials like limestone and dolomite. Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques. Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism.

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. In its pure form marble is a white stone with a crystalline and sugary appearance consisting of calcium carbonate caco 3 usually marble contains other minerals including quartz graphite pyrite and iron oxides these minerals can give marble a pink brown gray green or variegated coloration. It hails from different quarries and regions all over the world. Giving marble its smooth uniform appearance.

It should be noted that metamorphic rocks are not igneous. How is this wonderful material formed. Marble though does not have a layering effect because it is being subjected to equal pressure from all sides during its recrystallization.
