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.
Wehrlite 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 Wehrlite 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 Wehrlite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diatomite and Properties of Wehrlite. Learn more about Diatomite vs Wehrlite in the next section. The interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Wehrlite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Diatomite and Wehrlite, 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 Wehrlite include As dimension stone, Cobblestones.
More about Diatomite and Wehrlite
Here you can know more about Diatomite and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Wehrlite consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Diatomite vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Wehrlite is available in dark greenish - grey, green colors. Appearance of Diatomite is Soft and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Diatomite vs Wehrlite. The hardness of Diatomite is 1 and that of Wehrlite is 5.5-6. The types of Diatomite are Not Available whereas types of Wehrlite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diatomite and Wehrlite is white. The specific heat capacity of Diatomite is 0.90 kJ/Kg K and that of Wehrlite is 0.63 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 Wehrlite is heat resistant, impact resistant, pressure resistant.
