5 Formation

5.1 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.

Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

Diatomite vs Mylonite 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 Mylonite Reserves. Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth. Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism. 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. You can check out Diatomite vs Mylonite information and Diatomite vs Mylonite characteristics in the upcoming sections.

More about Diatomite and Mylonite

Here you can know more about Diatomite and Mylonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Mylonite consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Mylonite includes Porphyroblasts. You can also check out the list of all Sedimentary Rocks. When we have to compare Diatomite vs Mylonite, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Mylonite is available in black to grey colors. Appearance of Diatomite is Soft and that of Mylonite is Dull, Banded and Foilated. Properties of rock is another aspect for Diatomite vs Mylonite. The hardness of Diatomite is 1 and that of Mylonite is 3-4. The types of Diatomite are Not Available whereas types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diatomite and Mylonite is white. The specific heat capacity of Diatomite is 0.90 kJ/Kg K and that of Mylonite is 1.50 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 Mylonite is heat resistant, impact resistant, pressure resistant.
