Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks

Formation
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.
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

More about Wehrlite and Phyllite
Here you can know more about Wehrlite and Phyllite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Phyllite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Phyllite, the texture, color and appearance plays an important role in determining the type of rock. Wehrlite is available in dark greenish - grey, green colors whereas, Phyllite is available in black to grey, light greenish grey colors. Appearance of Wehrlite is Rough and Banded and that of Phyllite is Crinkled or Wavy. Properties of rock is another aspect for Wehrlite vs Phyllite. The hardness of Wehrlite is 5.5-6 and that of Phyllite is 1-2. The types of Wehrlite are Not Available whereas types of Phyllite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Phyllite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Phyllite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Wehrlite is heat resistant, impact resistant, pressure resistant whereas Phyllite is heat resistant, pressure resistant, water resistant.
