Formation

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.

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Diatomite vs Metapelite 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 Diatomite and Metapelite Reserves. Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth. Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone. 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 Diatomite and Metapelite

Here you can know more about Diatomite and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Metapelite consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Diatomite vs Metapelite, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Diatomite is Soft and that of Metapelite is Banded. Properties of rock is another aspect for Diatomite vs Metapelite. The hardness of Diatomite is 1 and that of Metapelite is 5-6. The types of Diatomite are Diatomite whereas types of Metapelite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diatomite is white while that of Metapelite is . The specific heat capacity of Diatomite is 0.90 kJ/Kg K and that of Metapelite is 0.72 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diatomite is heat resistant whereas Metapelite is heat resistant, impact resistant, pressure resistant.
