Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

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.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

Wehrlite vs Boninite 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. Wehrlite vs Boninite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Boninite. Learn more about Wehrlite vs Boninite in the next section. The interior uses of Wehrlite include Decorative aggregates and Interior decoration whereas the interior uses of Boninite include Decorative aggregates, Homes and Kitchens. Due to some exceptional properties of Wehrlite and Boninite, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Boninite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Wehrlite and Boninite
Here you can know more about Wehrlite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Boninite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Boninite, 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, Boninite is available in bluish - grey, brown, green, grey colors. Appearance of Wehrlite is Rough and Banded and that of Boninite is Dull and Soft. Properties of rock is another aspect for Wehrlite vs Boninite. The hardness of Wehrlite is 5.5-6 and that of Boninite is 7. The types of Wehrlite are Ultramafic rock whereas types of Boninite are Basalt. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Boninite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Boninite is 0.84 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 Boninite is heat resistant, impact resistant, pressure resistant, wear resistant.
