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.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

More about Wehrlite and Andesite
Here you can know more about Wehrlite and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Andesite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Andesite, 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, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Wehrlite is Rough and Banded and that of Andesite is Dull and Soft. Properties of rock is another aspect for Wehrlite vs Andesite. The hardness of Wehrlite is 5.5-6 and that of Andesite is 7. The types of Wehrlite are Ultramafic rock whereas types of Andesite are Icelandite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Andesite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Andesite is 2.39 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 Andesite is heat resistant, pressure resistant, wear resistant.
