Definition
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

Formation
Tachylite 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.
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 Tachylite and Wehrlite
Here you can know more about Tachylite and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Wehrlite consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Tachylite vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Wehrlite is available in dark greenish - grey, green colors. Appearance of Tachylite is Glassy and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Tachylite vs Wehrlite. The hardness of Tachylite is 5.5 and that of Wehrlite is 5.5-6. The types of Tachylite 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 Tachylite is vermilion while that of Wehrlite is white. The specific heat capacity of Tachylite is 0.56 kJ/Kg K and that of Wehrlite is 0.63 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Tachylite is heat resistant, impact resistant, wear resistant whereas Wehrlite is heat resistant, impact resistant, pressure resistant.
