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.
Pantellerite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Diatomite vs Pantellerite 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 Pantellerite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diatomite and Properties of Pantellerite. Learn more about Diatomite vs Pantellerite in the next section. The interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Pantellerite include Not available. Due to some exceptional properties of Diatomite and Pantellerite, they have various applications in construction industry. The uses of Diatomite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Source of calcium and that of Pantellerite include Na.
More about Diatomite and Pantellerite
Here you can know more about Diatomite and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Pantellerite consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite. You can also check out the list of all Sedimentary Rocks. When we have to compare Diatomite vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Diatomite is Soft and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Diatomite vs Pantellerite. The hardness of Diatomite is 1 and that of Pantellerite is 6-7. The types of Diatomite are Not Available whereas types of Pantellerite are Pantelleritic Ignimbrite. 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 Pantellerite is unknown. The specific heat capacity of Diatomite is 0.90 kJ/Kg K and that of Pantellerite is Not Available. 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 Pantellerite is heat resistant.
