The exact chemical composition of marble will greatly vary dependong on the location and the minerals or impurities present in the limestone during recrystallization.
Typically marble is composed of the following major constituents.
Table 6 2 presents the chemical compositions of the wmps were used in many different studies.
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 may be foliated.
However stonemasons use the term more broadly to encompass un metamorphosed limestone.
Marble dust is mixed with concrete cement or synthetic resins to make counters building stones and many other objects.
