Formation
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 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 vs Diatomite 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. Granulite vs Diatomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Diatomite. Learn more about Granulite vs Diatomite in the next section. The interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Granulite and Diatomite, they have various applications in construction industry. The uses of Granulite in construction industry include As dimension stone, Building houses or walls and that of Diatomite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Source of calcium.
More about Granulite and Diatomite
Here you can know more about Granulite and Diatomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Diatomite consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Diatomite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Diatomite is available in grey, white, yellow colors. Appearance of Granulite is Veined or Pebbled and that of Diatomite is Soft. Properties of rock is another aspect for Granulite vs Diatomite. The hardness of Granulite is 6-7 and that of Diatomite is 1. The types of Granulite are Not Available whereas types of Diatomite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Diatomite is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Diatomite is 0.90 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granulite is heat resistant, wear resistant whereas Diatomite is heat resistant.
