Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Icelandite belongs to volcanic igneous rocks which is rich in iron and belongs to andesite rock

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.
Icelandite 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 Icelandite
Here you can know more about Wehrlite and Icelandite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Icelandite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Icelandite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Icelandite, 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, Icelandite is available in bluish - grey, grey, pink, yellow colors. Appearance of Wehrlite is Rough and Banded and that of Icelandite is Dull and Soft. Properties of rock is another aspect for Wehrlite vs Icelandite. The hardness of Wehrlite is 5.5-6 and that of Icelandite is 7. The types of Wehrlite are Ultramafic rock whereas types of Icelandite are Intermediate volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Icelandite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Icelandite is 2.39 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 Icelandite is heat resistant, pressure resistant, scratch resistant, wear resistant.
