Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Litchfieldite is a rare igneous rock which is coarse-grained, foliated and a variety of nepheline syenite, sometimes also called as nepheline syenite gneiss or gneissic nepeheline syenite

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.
Litchfieldite 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 Litchfieldite
Here you can know more about Wehrlite and Litchfieldite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Litchfieldite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Litchfieldite 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 Litchfieldite, 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, Litchfieldite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Wehrlite is Rough and Banded and that of Litchfieldite is Banded and Foilated. Properties of rock is another aspect for Wehrlite vs Litchfieldite. Hardness of Wehrlite and Litchfieldite is 5.5-6. The types of Wehrlite are Ultramafic rock whereas types of Litchfieldite are Borolanite and Litchfieldite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Litchfieldite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Litchfieldite is 0.79 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 Litchfieldite is heat resistant, impact resistant, wear resistant.
