White marble chemical composition.

That means it is born from the transformation of a pre existing rock whose composition and structure underwent changes over the time caused by the intervention of different chemical and physical factors. Specimen is about 1 1 4 inches across about 3 centimeters. 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. 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.

Petrographically marbles are massive rather than thin layered and consist of a. Limestone crystals are much smaller than that of marble and limestone is much more porous. This specimen is a piece of white marble with a large red ruby crystal from afghanistan. Marble is made of calcium carbonate caco3 which is also what limestone is made from.

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. Marble is often the host rock for corundum spinel and other gem minerals.

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 metamorphic rock formed when limestone is subjected to high pressure or heat. Marble is commonly used for sculpture and as a building material.
