Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

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.
Wehrlite 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.

More about Eclogite and Wehrlite
Here you can know more about Eclogite and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Wehrlite 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 Wehrlite includes Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, colourless, green, grey, pink, white colors whereas, Wehrlite is available in dark greenish - grey, green colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Eclogite vs Wehrlite. The hardness of Eclogite is 3.5-4 and that of Wehrlite is 5.5-6. The types of Eclogite are Not Available whereas types of Wehrlite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Wehrlite is white. The specific heat capacity of Eclogite is Not Available and that of Wehrlite is 0.63 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 Wehrlite is heat resistant, impact resistant, pressure resistant.
