Formation

Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

Blueschist vs Marble Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Blueschist and Marble Reserves. Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature. Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes.

More about Blueschist and Marble

Here you can know more about Blueschist and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Blueschist and Marble consists of mineral content and compound content. The mineral content of Blueschist includes Albite, Chlorite, Epidote, Garnet, Glaucophane, Lawsonite, Muscovite or Illite, Quartz and mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Blueschist vs Marble, the texture, color and appearance plays an important role in determining the type of rock. Blueschist is available in blue, bluish - grey, purple, shades of blue colors whereas, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Blueschist is Dull and Banded and that of Marble is Veined and Shiny. Properties of rock is another aspect for Blueschist vs Marble. The hardness of Blueschist is 3.5-4 and that of Marble is 3-4. The types of Blueschist are Metamorphic rock whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Blueschist is white to grey while that of Marble is white. The specific heat capacity of Blueschist is 0.84 kJ/Kg K and that of Marble is 0.88 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Blueschist is impact resistant, pressure resistant whereas Marble is heat resistant.
