Definition
Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

Archaeological Significance
Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

More about Scoria and Eclogite
Here you can know more about Scoria and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Eclogite consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica 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 Scoria vs Eclogite, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Eclogite is available in black, brown, green, grey, pink, white colors. Appearance of Scoria is Glassy and Vesicular and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Scoria vs Eclogite. The hardness of Scoria is 5-6 and that of Eclogite is 3.5-4. The types of Scoria are Basaltic Scoria and Andesitic Scoria 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 Scoria and Eclogite is white. The specific heat capacity of Scoria 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.Scoria is heat resistant, impact resistant, pressure resistant, wear resistant whereas Eclogite is heat resistant.
