Definition
Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

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.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

Diatomite vs Eclogite 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 Eclogite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diatomite and Properties of Eclogite. Learn more about Diatomite vs Eclogite in the next section. The interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Eclogite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Diatomite and Eclogite, 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 Eclogite include Not yet used.
More about Diatomite and Eclogite
Here you can know more about Diatomite and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Eclogite consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite. You can also check out the list of all Sedimentary Rocks. When we have to compare Diatomite vs Eclogite, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Eclogite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Diatomite is Soft and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Diatomite vs Eclogite. The hardness of Diatomite is 1 and that of Eclogite is 3.5-4. The types of Diatomite are Not Available whereas types of Eclogite 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 Eclogite is white. The specific heat capacity of Diatomite is 0.90 kJ/Kg K and that of Eclogite 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 Eclogite is heat resistant.
