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.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

Diatomite vs Pumice 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 Pumice Reserves. Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. 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 Pumice information and Diatomite vs Pumice characteristics in the upcoming sections.

Diatomite vs Pumice Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Diatomite vs Pumice characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diatomite and Properties of Pumice. Learn more about Diatomite vs Pumice in the next section. The interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Pumice include Decorative aggregates, Flooring, Homes and Interior decoration.

More about Diatomite and Pumice

Here you can know more about Diatomite and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Pumice consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica. You can also check out the list of all Sedimentary Rocks. When we have to compare Diatomite vs Pumice, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Diatomite is Soft and that of Pumice is Vesicular. Properties of rock is another aspect for Diatomite vs Pumice. The hardness of Diatomite is 1 and that of Pumice is 6. The types of Diatomite are Not Available whereas types of Pumice are Scoria. 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 Pumice is white, greenish white or grey. The specific heat capacity of Diatomite is 0.90 kJ/Kg K and that of Pumice is 0.87 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 Pumice is impact resistant, pressure resistant.
