Definition
Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

Formation
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

Diabase 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. Diabase vs Eclogite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diabase and Properties of Eclogite. Learn more about Diabase vs Eclogite in the next section. The interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens whereas the interior uses of Eclogite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Diabase and Eclogite, they have various applications in construction industry.

More about Diabase and Eclogite
Here you can know more about Diabase and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Eclogite consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine 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 Igneous Rocks. When we have to compare Diabase vs Eclogite, the texture, color and appearance plays an important role in determining the type of rock. Diabase is available in dark grey to black colors whereas, Eclogite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Diabase is Vesicular and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Diabase vs Eclogite. The hardness of Diabase is 7 and that of Eclogite is 3.5-4. The types of Diabase 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 Diabase is black while that of Eclogite is white. The specific heat capacity of Diabase is Not Available 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.Diabase is heat resistant, impact resistant, pressure resistant, wear resistant whereas Eclogite is heat resistant.
