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.

Is marble a silicate.

The crystals become larger as the level of metamorphism progresses. Marble that has been exposed to low levels of metamorphism will have very small calcite crystals. And is a main ingredient in many cosmetics. This process generally increases the average grain size which gives marble its sparkling appearance.

Clay minerals within the marble will alter to micas and more complex silicate structures as the level of metamorphism increases. Talc is a clay mineral composed of hydrated magnesium silicate with the chemical formula mg 3 si 4 o 10 oh 2 talc in powdered form often combined with corn starch is used as baby powder this mineral is used as a thickening agent and lubricant. However mostly because of marketing reasons some coarse grained limestones grainstones and dolomites are also sold as marble. Often mistaken for marble is serpentine which is actually magnesium silicate based as opposed to calcite based.

Pure white marble is the result of metamorphism of a very pure silicate poor limestone or dolomite protolith. Calc silicate marble the term marble in geology is restricted to metamorphic rocks in which the carbonate minerals have recrystallized. It is bounded by heterogeneous calc silicate quartz calcite rocks which we interpret as the metamorphic product of interlayered siliceous rocks metachert and dolomitic carbonate. Albitite is a hydrothermal metasomatic rock that may superficially resemble marble but it is composed of silicate feldspar group mineral albite.

The characteristic swirls and veins of many colored marble varieties are usually due to various mineral impurities such as clay silt sand iron oxides or chert which were originally present as grains or layers in the limestone. The marble lens is 5 m thick and 50 m long and is situated in the nose of a minor fold that is parasitic on the early isoclinal closure in the potassic felsic schist unit. This silicate rich marble of the lewisian group was originally deposited as a limestone in the late archean. Width of sample 11 cm.

Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. As a result of the different mineralogy and whole rock chemistry of serpentine it exhibits greater acid resistance and abrasion resistance than does a true marble. Marble is a metamorphic rock.
