Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles

Etymology
From French, Greek eklogē selection with reference to the selective content of the rock + -ite1
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

Features
Available in Lots of Colors and Patterns, Generally rough to touch, Is one of the oldest rock
High silica content, Host Rock for Lead
Archaeological Significance
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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

Eclogite vs Turbidite 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 Turbidite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Eclogite and Properties of Turbidite. Learn more about Eclogite vs Turbidite in the next section. The interior uses of Eclogite include Decorative aggregates and Interior decoration whereas the interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Eclogite and Turbidite, they have various applications in construction industry. The uses of Eclogite in construction industry include and that of Turbidite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement.
More about Eclogite and Turbidite
Here you can know more about Eclogite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Turbidite 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 Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, green, grey, pink, white colors whereas, Turbidite is available in black, brown, green, grey, pink colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Eclogite vs Turbidite. The hardness of Eclogite is 3.5-4 and that of Turbidite is 3. The types of Eclogite are Eclogite whereas types of Turbidite are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite is white while that of Turbidite is white, greenish white or grey. The specific heat capacity of Eclogite is 0.75 kJ/Kg K and that of Turbidite is 0.92 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 Turbidite is heat resistant.
