Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Shonkinite is a rare, dark-coloured and intrusive igneous rock which contains augite and orthoclase feldspar as its primary constituents

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.
Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

More about Wehrlite and Shonkinite
Here you can know more about Wehrlite and Shonkinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Shonkinite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Shonkinite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Shonkinite, 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, Shonkinite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Wehrlite is Rough and Banded and that of Shonkinite is Banded and Foilated. Properties of rock is another aspect for Wehrlite vs Shonkinite. Hardness of Wehrlite and Shonkinite is 5.5-6. The types of Wehrlite are Not Available whereas types of Shonkinite 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 Shonkinite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Shonkinite 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.Wehrlite is heat resistant, impact resistant, pressure resistant whereas Shonkinite is heat resistant, impact resistant, wear resistant.
