Marble As A Rock

The stone we call marble is a metamorphic rock mostly composed of calcite a type of calcium carbonate formed as a result of changes brought about in the structure of sedimentary or igneous rocks by extreme pressure or heat.

Marble as a rock.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Marble is commonly used for sculpture and as a building material. Petrographically marbles are massive rather than thin layered and consist of a. Characteristics of marble as a sculptural material.

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. Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques. Form of it when limestone buried deep in the older layers of earth s crust is subjected to heat and pressure from thick layers of overlying sediments. 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 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.
