Definition
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
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

Formation
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.
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 Adakite and Wehrlite
Here you can know more about Adakite and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adakite and Wehrlite consists of mineral content and compound content. The mineral content of Adakite includes Olivine, Plagioclase, Pyroxene and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Adakite vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Adakite is available in black, brown, light to dark grey colors whereas, Wehrlite is available in dark greenish - grey, green colors. Appearance of Adakite is Dull and Soft and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Adakite vs Wehrlite. The hardness of Adakite is 3-4 and that of Wehrlite is 5.5-6. The types of Adakite are Not Available 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 Adakite is bluish black while that of Wehrlite is white.
