What Is The Composition Of Marble Rock

Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.

What is the composition of marble rock. 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. What is the chemical composition of marble. It has a greater number of potential uses than almost any other rock type. Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques.

The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the. Marble marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. 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.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. 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. Form of it when limestone buried deep in the older layers of earth s crust is subjected to heat and pressure from thick layers of overlying sediments. Marble is commonly used for sculpture and as a building material.

Marble is a non foliated metamorphic rock that forms through the metamorphism of limestone. Recrystallized dolomitic limestone producing interlocking grains of dolomite. Marble is a metamorphic rock of calcareous composition and often of a layered structure. Typically marble is composed of the following major constituents.

The exact chemical composition of marble will greatly vary dependong on the location and the minerals or impurities present in the limestone during recrystallization. Marble is a granular metamorphic rock it is derived from limestone or dolomite and it consists of a mass of interlocking grains of calcite or the mineral dolomite. Petrographically marbles are massive rather than thin layered and consist of a. 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.
