What Sedimentary Rock Is Marble Formed From

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the earth s surface.

What sedimentary rock is marble formed from. Sedimentary rocks are the most common rocks exposed on the earth s surface but are only a minor constituent of the entire crust. 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 formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism. 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.

Sedimentary rocks are as the name suggests formed from the buildup of sediment. Sedimentary rocks are formed on or near the earth s surface in contrast to metamorphic and igneous rocks which are formed deep within the earth. Sedimentary rock rock formed at or near the earth s surface by the accumulation and lithification of sediment or by the precipitation from solution at normal surface temperatures. Nonfoliated rocks can also form by metamorphism which happens when magma comes in contact with the surrounding rock.

This means they form over time on the surface of the earth unlike other types of rock such as igneous or metamorphic which are created deep within the earth under great pressure or heat.

During metamorphism the calcite limestone recrystallizes forming the interlocking calcite crystals that make up the marble. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. Sedimentation is the collective name for processes that cause these particles to settle in place. 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.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
