Limestone Turns Into Marble

It is used in glass making.

Limestone turns into marble.

It helps clean drinking water and treat sewage. When the heat and pressure hits the limestone calcite seed crystals form. 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. Limestone turns into the metamorphic rock marble when it is subjected to high amounts of pressure and heat.

Limestone is hard enough to resist weathering but usually soft enough to be worked cut and carved by stonemasons. Layers of crushed limestone are placed underneath roads and underneath railroad tracks. 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. Because marble is a fairly soft material only a three on the mohs hardness scale it is easy to cut and carve.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. The calcite in the limestone changes and fossils and layering in the original limestone disappear as interlocking grains grow. Marble is commonly used for sculpture and as a building material. It is composed primarily of the mineral calcite caco3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite.

Limestone is important to making cement. When limestone is heated to a high temperature and squeezed at the base of a mountain it recrystallizes into the metamorphic rock marble marbles are fairly dense relatively easy to cut or be shaped into blocks and some forms are white in colour. As the rock is subject to natural heat and pressure it recrystallizes growing harder and denser over time. Marble is a metamorphic rock formed by the alteration of limestone by heat and pressure.

If the limestone is pure a white marble is formed. When limestone experiences high heat and pressure beneath the earth it may transform into marble a metamorphic rock. With continued metamorphism these crystal seeds grow while any clay deposits in the limestone transform into silicate structures such as mica. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
