Marble Is A Rock

Marble is a metamorphic rock.

Marble is a rock.

Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. It is usually a light colored rock. The original rock is subjected to heat and pressure causing profound physical or chemical change. 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.

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. Marble is commonly used for sculpture and as a building material. Marble is a type of very hard rock which feels cold when you touch it and which shines. Marble is developed from limestone which is a sedimentary rock.

The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the. Marble marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques. Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form.

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. 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 is a granular metamorphic rock it is derived from limestone or dolomite and it consists of a mass of interlocking grains of calcite or the mineral dolomite.

Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.
