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

Formation
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 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 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. Eclogite vs Diatomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Eclogite and Properties of Diatomite. Learn more about Eclogite vs Diatomite in the next section. The interior uses of Eclogite include Decorative aggregates and Interior decoration whereas the interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Eclogite and Diatomite, they have various applications in construction industry. The uses of Eclogite in construction industry include Not yet used and that of Diatomite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Source of calcium.
More about Eclogite and Diatomite
Here you can know more about Eclogite and Diatomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Diatomite consists of mineral content and compound content. The mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite 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 Eclogite vs Diatomite, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, colourless, green, grey, pink, white colors whereas, Diatomite is available in grey, white, yellow colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Diatomite is Soft. Properties of rock is another aspect for Eclogite vs Diatomite. The hardness of Eclogite is 3.5-4 and that of Diatomite is 1. The types of Eclogite 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 Eclogite and Diatomite is white. The specific heat capacity of Eclogite is Not Available 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.Eclogite is heat resistant whereas Diatomite is heat resistant.
