Chemical Composition Of Marble

The only difference between limestone and marble is the crystalline structure.

Chemical composition of marble. Marble is made of calcium carbonate caco3 which is also what limestone is made from. Chemical composition it is made of mostly calcium carbonate caco3 with minor amounts silica magnesium carbonate silica iron oxide aluminium oxide etc. 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. Along with calcite and aragonite dolomite makes up approximately 2 percent of the earth s crust.

Limestone crystals are much smaller than that of marble and limestone is much more porous. Learn more about the structure properties and uses of dolomite in this article. Marble is commonly used for sculpture and as a building material. Table 6 2 presents the chemical compositions of the wmps were used in many different studies.

Dolomite is a common rock forming mineral it is a calcium magnesium carbonate with a chemical composition of camg co 3 2 it is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble limestone that contains some dolomite is known as dolomitic limestone. 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. When the distribution of the main components in the table is examined it is noted. 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.

The following is the analysis made by professors daniel and wheatstone for the commissioners who selected the stone for the houses of parliament. Dolomite type of limestone the carbonate fraction of which is dominated by the mineral dolomite calcium magnesium carbonate. Formation of the marble. Marble is composed primarily of calcite dolotimite or perhaps serpentine and other similar minerals.

Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. The exact chemical composition of marble will greatly vary dependong on the location and the minerals or impurities present in the limestone during recrystallization. Chemical analysis and quantitative mineralogical characterizations of the wmp usually are done using x ray diffraction.
