What Makes Marble More Valued Compared To Its Parent Rock Limestone

Limestone a sedimentary rock forms when shells sand and fossils solidify over millions of years.

What makes marble more valued compared to its parent rock limestone.

The internal carbonate crystal structure of limestone and marble are different to each other. If you look closely at a limestone you can usually see fossil fragments for example bits of shell held together by a calcite matrix. 6 limestone has gray white or black colors while marble although most commonly. 4 heat and pressure causes the formation of marble while they are not necessary for the formation of limestone.

Travertine ˈ t r æ v ər ˌ t iː n tra vər teen is a form of limestone deposited by mineral springs especially hot springs travertine often has a fibrous or concentric appearance and exists in white tan cream colored and even rusty varieties. During metamorphism the calcite limestone recrystallizes forming the interlocking calcite crystals that make up the marble. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. 3 limestone is a sedimentary rock while marble is a metamorphic rock.

It is formed by a process of rapid precipitation of calcium carbonate often at the mouth of a hot spring or in a limestone cave. Limestone are marble are chemically the same rock. Marble is more expensive than limestone and is famous for its. When limestone experiences high heat and pressure beneath the earth it may transform into marble a metamorphic rock.

Limestone is more porous than marble because there are small openings between. 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. Limestone is a type of sedimentary rock formed by the deposition of natural carbonate material whereas marble is a type of metamorphic rock formed by metamorphism of limestone. Sedimentary rocks are made of you guessed it sediments.

As the rock is subject to natural heat and pressure it recrystallizes growing harder and denser over time. 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 formed when limestone is subjected to high pressure or heat. The difference is in how they are formed.

Limestone is a sedimentary rock and marble is metamorphic. 5 limestone is more porous than marble while marble is harder than limestone. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism.
