White Metamorphic Marble

White marble is a common material for statues.

White metamorphic marble.

Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. A crystalline rock formed as a result of the recrystallization of limestone or dolomite. Marble is a coarse grained metamorphic rock that can be many colors including white pink yellow brown green or black. Like other metamorphic rocks marble has no fossils and any layering that appears in it probably does not correspond to the original bedding of the precursor 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. The term marble is applied commercially to any metamorphic rock of medium hardness that can be polished. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Quartzite is a very hard natural stone.

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. 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. The original rock type was limestone. Most of the white and gray marbles of alabama georgia and western new england and that from yule colorado are recrystallized rocks as are a number of greek and italian statuary marbles famous from antiquity which are still quarried these include the parian marble the pentelic marble of attica in which phidias praxiteles and other greek sculptors executed their principal works and.

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 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.

This category of rock includes marble marmorized limestone dense dolomite ophicalcite calcareous breccia and calcareous conglomerates. The color of marble can range from the purest white to black ranging through the warmer colors in between depending on the other mineral impurities. The hardness extra strength with elegant marble look makes quartzite countertops attractive for kitchens bathroom vanity tops. Foliated metamorphic rocks such as gneiss phyllite schist and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure.
