Is Marble Monomineralic

Common monomineralic metamorphic rocks are marble and quartzite although they do not need necessarily to be monomineralic.

Is marble monomineralic.

This is the most important difference between most igneous monomineralic rocks which need to be more than 90. 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. Common monomineralic metamorphic rocks are marble and quartzite although they do not need necessarily to be monomineralic. Monomineralic igneous rocks are dunite more than 90 olivine and anorthosite more than 90 plagioclase feldspar.

Similar is the situation with their sedimentary protoliths limestone and sandstone which may be very pure. Monomineralic applied to rocks composed of one mineral type only. Marble is commonly used for sculpture and as a building material. Examples would include the igneous rock anorthosite composed entirely of plagioclase feldspar and the metamorphic rock marble composed entirely of calcite.

The mineral content and grain structure of two rock types are identified using petrographic thin sections.
