Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Ijolite is an intrusive igneous rock which is composed mainly of nepheline and an alkali pyroxene, usually aegirine-augite

Archaeological Significance
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.
Ijolite 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 Wehrlite and Ijolite
Here you can know more about Wehrlite and Ijolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Ijolite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Ijolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Ijolite, 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, Ijolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Wehrlite is Rough and Banded and that of Ijolite is Banded and Foilated. Properties of rock is another aspect for Wehrlite vs Ijolite. Hardness of Wehrlite and Ijolite is 5.5-6. The types of Wehrlite are Ultramafic rock whereas types of Ijolite are Alkaline rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Ijolite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Ijolite is 0.84 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 Ijolite is heat resistant, impact resistant, wear resistant.
