Marble Is A Metamorphic Rock That Forms From

The rock on the right has randomly arranged grains.

Marble is a metamorphic rock that forms from. The rock on the left formed from granite. Metamorphism causes variable recrystallization of the original carbonate mineral grains. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. The rock on the left is formed from cooled magma.

These are two metamorphic rocks. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals. These minerals can give marble a pink brown gray green or variegated coloration. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth.

In this hand specimen of vermont marble the crystals are small. The rock on the right is foliated. 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. Metamorphic rock can be marble because marble is a form of metamorphic rock which is composed of coarse crystals from parent limestone or dolostone rocks.

In its pure form marble is a white stone with a crystalline and sugary appearance consisting of calcium carbonate caco 3. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. Metamorphic rock forms from pre existing rock when heat and pressure cause solid state transformations. Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals.

This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock. Nonfoliated metamorphic rocks such as marble and quartzite derived their metamorphism more from heat than from directional pressure. Slate is another common metamorphic rock that forms from shale. 1 marble is a metamorphic rock that forms from a protolith.
