Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
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 Charnockite and Wehrlite
Here you can know more about Charnockite and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Wehrlite consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Charnockite is available in black, grey, orange, pink, white colors whereas, Wehrlite is available in dark greenish - grey, green colors. Appearance of Charnockite is Veined or Pebbled and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Charnockite vs Wehrlite. The hardness of Charnockite is 6-7 and that of Wehrlite is 5.5-6. The types of Charnockite are Enderbite 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 Charnockite and Wehrlite is white. The specific heat capacity of Charnockite 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.Charnockite is heat resistant, wear resistant whereas Wehrlite is heat resistant, impact resistant, pressure resistant.
