White Marble Chemical Composition

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.

White marble chemical composition.

Scientifically marble is a carbonate rock which originated from metamorphic genesis. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. 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. Petrographically marbles are massive rather than thin layered and consist of a.

The only difference between limestone and marble is the crystalline structure. Marble is often the host rock for corundum spinel and other gem minerals. Typically marble is composed of the following major constituents. Specimen is about 1 1 4 inches across about 3 centimeters.

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 made of calcium carbonate caco3 which is also what limestone is made from. This specimen is a piece of white marble with a large red ruby crystal from afghanistan.

Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques. Limestone crystals are much smaller than that of marble and limestone is much more porous. The exact chemical composition of marble will greatly vary dependong on the location and the minerals or impurities present in the limestone during recrystallization.
