Definition
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

Features
Always found as volcanic pipes over deep continental crust, Host rock for Diamond, Is one of the oldest rock, Surfaces are often shiny
Available in Lots of Colors and Patterns, Generally rough to touch, Is one of the oldest rock
Archaeological Significance
Formation
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

The uses of Appinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Eclogite include .
More about Appinite and Eclogite
Here you can know more about Appinite and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Appinite and Eclogite consists of mineral content and compound content. The mineral content of Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene 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 Appinite vs Eclogite, the texture, color and appearance plays an important role in determining the type of rock. Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Eclogite is available in black, brown, green, grey, pink, white colors. Appearance of Appinite is Dull, Banded and Foilated and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Appinite vs Eclogite. The hardness of Appinite is 5-6 and that of Eclogite is 3.5-4. The types of Appinite are Igneous rock whereas types of Eclogite are Eclogite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Appinite and Eclogite is white. The specific heat capacity of Appinite is 0.84 kJ/Kg K and that of Eclogite is 0.75 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Appinite is heat resistant, impact resistant whereas Eclogite is heat resistant.
