Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar

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.
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

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