Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

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.
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Adakite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Wehrlite and Adakite
Here you can know more about Wehrlite and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Adakite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Adakite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Adakite, 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, Adakite is available in black, brown, light to dark grey colors. Appearance of Wehrlite is Rough and Banded and that of Adakite is Dull and Soft. Properties of rock is another aspect for Wehrlite vs Adakite. The hardness of Wehrlite is 5.5-6 and that of Adakite is 3-4. The types of Wehrlite are Not Available whereas types of Adakite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite is white while that of Adakite is bluish black. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Adakite 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 Adakite is heat resistant, pressure resistant, wear resistant.
