Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Vogesite is a porphyritic alkaline igneous rock and is a variety of Lamprophyre which is dominated by essential amphibole, usually hornblende, and potassic feldspar

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.
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

More about Wehrlite and Vogesite
Here you can know more about Wehrlite and Vogesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Vogesite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Vogesite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Vogesite, 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, Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Wehrlite is Rough and Banded and that of Vogesite is Dull, Banded and Foilated. Properties of rock is another aspect for Wehrlite vs Vogesite. The hardness of Wehrlite is 5.5-6 and that of Vogesite is 5-6. The types of Wehrlite are Ultramafic rock whereas types of Vogesite are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Vogesite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Vogesite is 0.84 kJ/Kg K.
