Limestone turn into marble. When the heat and pressure hits the limestone calcite seed crystals form. The calcite in the limestone changes and fossils and layering in the original limestone disappear as interlocking grains grow. 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. 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. 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. When limestone is buried and put under intense heat and pressure why does it turn to marble instead of thermally decomposing into calcium oxide and carbon dioxide. Limestone change into marble when a great heat and pressure come from the under of the earth change into marble.
Marble forms when sedimentary limestone is. Marble is commonly used for sculpture and as a building material. This oil field was discovered in 1988 and is part of what is commonly known as the tawn field complex. If the limestone is pure a white marble is formed.
With continued metamorphism these crystal seeds grow while any clay deposits in the limestone transform into silicate structures such as mica. Limestones may include layers of clay or sand which may form the attractive flow banding and colours found in decorative marble. 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 forms when shells sand and mud are deposited at the bottom of oceans and lakes and over time solidify into rock.
