Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism

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.
Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.

More about Wehrlite and Greenschist
Here you can know more about Wehrlite and Greenschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Greenschist consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Greenschist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Serpentine, Sillimanite, Staurolite, Talc. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Greenschist, 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, Greenschist is available in dark greenish - grey, green colors. Appearance of Wehrlite is Rough and Banded and that of Greenschist is Layered and Shiny. Properties of rock is another aspect for Wehrlite vs Greenschist. The hardness of Wehrlite is 5.5-6 and that of Greenschist is 3.5-4. The types of Wehrlite are Ultramafic rock whereas types of Greenschist are Metamorphic rock.
