Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
Kenyte is a variety of porphyritic phonolite or trachyte rock with rhomb shaped phenocrysts of anorthoclase with variable olivine and augite in a glassy matrix

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.
Kenyte is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Due to some exceptional properties of Eclogite and Kenyte, they have various applications in construction industry. The uses of Eclogite in construction industry include and that of Kenyte include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics.
More about Eclogite and Kenyte
Here you can know more about Eclogite and Kenyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Kenyte 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 Kenyte includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Kenyte, 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, Kenyte is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Kenyte is Banded and Foilated. Properties of rock is another aspect for Eclogite vs Kenyte. The hardness of Eclogite is 3.5-4 and that of Kenyte is 5.5-6. The types of Eclogite are Eclogite whereas types of Kenyte are Foidolite. 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 Kenyte is white, greenish white or grey. The specific heat capacity of Eclogite is 0.75 kJ/Kg K and that of Kenyte is 0.84 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 Kenyte is heat resistant, impact resistant, wear resistant.
