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.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Diatomite vs Granulite 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 Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diatomite and Properties of Granulite. Learn more about Diatomite vs Granulite in the next section. The interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Diatomite and Granulite, 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 Granulite include As dimension stone, Building houses or walls.
More about Diatomite and Granulite
Here you can know more about Diatomite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Granulite consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Diatomite vs Granulite, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Granulite is available in black, brown colors. Appearance of Diatomite is Soft and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Diatomite vs Granulite. The hardness of Diatomite is 1 and that of Granulite is 6-7. The types of Diatomite are Not Available whereas types of Granulite 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 Granulite is white. The specific heat capacity of Diatomite is 0.90 kJ/Kg K and that of Granulite is 0.14 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 Granulite is heat resistant, wear resistant.
