Definition
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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.

Serpentinite vs Wehrlite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Serpentinite vs Wehrlite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Wehrlite. Learn more about Serpentinite vs Wehrlite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Wehrlite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Serpentinite and Wehrlite, they have various applications in construction industry. The uses of Serpentinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement and that of Wehrlite include As dimension stone, Cobblestones.
More about Serpentinite and Wehrlite
Here you can know more about Serpentinite and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Wehrlite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Wehrlite is available in dark greenish - grey, green colors. Appearance of Serpentinite is Rough and Dull and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Serpentinite vs Wehrlite. The hardness of Serpentinite is 3-5 and that of Wehrlite is 5.5-6. The types of Serpentinite are Jadeitite whereas types of Wehrlite are Ultramafic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Wehrlite is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Wehrlite is 0.63 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Serpentinite is heat resistant whereas Wehrlite is heat resistant, impact resistant, pressure resistant.
