Marble Is Metamorphic Rock From Limestone

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.

Marble is metamorphic rock from limestone.

Marble marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals. These rocks are both composed of the same mineral. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.

Metamorphism causes variable recrystallization of the original carbonate mineral grains. 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 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 main difference between limestone and marble is that limestone is a sedimentary rock typically composed of calcium carbonate fossils and marble is a metamorphic rock.

Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Both high temperatures and pressures contribute to recrystallization. What test could you perform on the rocks to be sure.

These minerals can give marble a pink brown gray green or variegated coloration. In its pure form marble is a white stone with a crystalline and sugary appearance consisting of calcium carbonate caco 3. Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism. The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the calcite during metamorphism.

A analyze the samples of sedimentary limestone and metamorphic marble in fig. For instance the small calcite crystals in the sedimentary rock limestone and chalk change into larger crystals in the metamorphic rock marble. Limestone forms when shells sand and mud are deposited at the bottom of oceans and lakes and over time solidify into rock. Marble is a rock resulting from metamorphism of sedimentary carbonate rocks most commonly limestone or dolomite rock.

How is the texture of these two rocks different limestone martie figure a7 3 1 b figure a7 3 2 shows three metamorphic rocks that had a mudstone. Usually marble contains other minerals including quartz graphite pyrite and iron oxides. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.
