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.

Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.

More about Blueschist and Diatomite

Here you can know more about Blueschist and Diatomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Blueschist and Diatomite 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 Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Blueschist vs Diatomite, 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, Diatomite is available in grey, white, yellow colors. Appearance of Blueschist is Dull and Banded and that of Diatomite is Soft. Properties of rock is another aspect for Blueschist vs Diatomite. The hardness of Blueschist is 3.5-4 and that of Diatomite is 1. The types of Blueschist are Metamorphic rock whereas types of Diatomite are Diatomite. 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 Diatomite is white. The specific heat capacity of Blueschist is 0.84 kJ/Kg K and that of Diatomite is 0.90 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 Diatomite is heat resistant.
