Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

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.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

More about Wehrlite and Basanite
Here you can know more about Wehrlite and Basanite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Basanite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Basanite , 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, Basanite is available in black, brown, green, grey, red, white colors. Appearance of Wehrlite is Rough and Banded and that of Basanite is Glassy or Pearly. Properties of rock is another aspect for Wehrlite vs Basanite . The hardness of Wehrlite is 5.5-6 and that of Basanite is 7. The types of Wehrlite are Not Available whereas types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Basanite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Basanite is 0.74 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 Basanite is heat resistant, impact resistant, pressure resistant, wear resistant.
