Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Borolanite is a variety of Nepheline Syenite and belongs to igneous rocks and contains nepheline-alkali feldspar pseudomorphs which occur as conspicuous white spots in the dark rock matrix

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.
Borolanites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

More about Wehrlite and Borolanite
Here you can know more about Wehrlite and Borolanite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Borolanite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Borolanite 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 Borolanite, 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, Borolanite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Wehrlite is Rough and Banded and that of Borolanite is Banded and Foilated. Properties of rock is another aspect for Wehrlite vs Borolanite. Hardness of Wehrlite and Borolanite is 5.5-6. The types of Wehrlite are Ultramafic rock whereas types of Borolanite are -.
