What Rock Turns Into Marble

Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques.

What rock turns into marble. Even though slate is a metamorphic rock it still looks a lot like a sedimentary rock it is still in thin layers. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Each kind of sedimentary rock turns into a different kind of metamorphic rock. This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock.

Shale turns into slate sandstone turns into quartzite. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Marble granular limestone or dolomite i e rock composed of calcium magnesium carbonate that has been recrystallized under the influence of heat pressure and aqueous solutions. Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals.

This makes marble a useful material for creating sculptures with along with decorative. This occurs when limestone for example is subjected to heat and pressure and turns into a more coarsely crystalline and sometimes banded rock called marble. Slate is another common metamorphic rock that forms from shale. Because marble is a fairly soft material only a three on the mohs hardness scale it is easy to cut and carve.

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.

Nonfoliated rocks can also form by metamorphism which happens when magma comes in contact with the surrounding rock. With continued metamorphism these crystal seeds grow while any clay deposits in the limestone transform into silicate structures such as mica. Sedimentary rocks like bituminous coal limestone and sandstone given enough heat and pressure can turn into nonfoliated metamorphic rocks like anthracite coal marble and quartzite. The sedimentary rocks limestone and dolostone dolomite become the metamorphic rock marble under conditions of high pressure and or heat.

Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met.
