Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

Eclogite vs Suevite 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 Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Eclogite and Properties of Suevite. Learn more about Eclogite vs Suevite in the next section. The interior uses of Eclogite include Decorative aggregates and Interior decoration whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Eclogite and Suevite, they have various applications in construction industry. The uses of Eclogite in construction industry include and that of Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Eclogite and Suevite
Here you can know more about Eclogite and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Suevite 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 Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Suevite, 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, Suevite is available in black, brown, green, grey, pink colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Suevite is Banded. Properties of rock is another aspect for Eclogite vs Suevite. The hardness of Eclogite is 3.5-4 and that of Suevite is 5.5. The types of Eclogite are Eclogite whereas types of Suevite are Phyllosilicates, Calcite. 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 Suevite is light to dark brown. The specific heat capacity of Eclogite is 0.75 kJ/Kg K and that of Suevite 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 Suevite is heat resistant.
