Is Marble Metamorphic Rock

Foliated means the parallel arrangement of certain mineral grains that gives the rock a striped appearance.

Is marble metamorphic rock. Marble is commonly used for sculpture and as a building material. Slate is another common metamorphic rock that forms from shale. The specimen shown above is about two inches five centimeters across. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.

The preexisting rocks may be igneous sedimentary or other metamorphic rocks. Marble is a non foliated metamorphic rock that is produced from the metamorphism of limestone or dolostone. 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. Metamorphic rock any rock that results from the alteration of preexisting rocks in response to changing conditions such as variations in temperature pressure and mechanical stress and the addition or subtraction of chemical components.

Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. 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. Some kinds of metamorphic rocks granite gneiss and biotite schist are two examples are strongly banded or foliated.

This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Lapis lazuli the famous blue gem material is actually a metamorphic rock.

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. Common metamorphic rocks include phyllite schist gneiss quartzite and marble. Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals.

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.
