Limestone Marble Metamorphic Rock

Marble is commonly used for sculpture and as a building material.

Limestone marble metamorphic rock.

A analyze the samples of sedimentary limestone and metamorphic marble in fig. Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form. 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.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. They make rocks smaller. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals.

During metamorphism the calcite limestone recrystallizes forming the interlocking calcite crystals that make up the marble. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. 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 forms when shells sand and mud are deposited at the bottom of oceans and lakes and over time solidify into rock.

Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Which words or phrases describe slate. Marble marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. 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.

Gneiss limestone marble slate. 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. They change existing minerals. Marble forms when sedimentary limestone is.

These rocks are both composed of the same mineral. Which type of rock is non foliated 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. 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.

In the formation of metamorphic rocks what effect do temperature and pressure primarily have.
