Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine

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.
Norite 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.

Wehrlite vs Norite 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 Norite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Norite. Learn more about Wehrlite vs Norite in the next section. The interior uses of Wehrlite include Decorative aggregates and Interior decoration whereas the interior uses of Norite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Wehrlite and Norite, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Norite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Wehrlite and Norite
Here you can know more about Wehrlite and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Norite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Norite, 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, Norite is available in dark grey to black colors. Appearance of Wehrlite is Rough and Banded and that of Norite is Veined and Shiny. Properties of rock is another aspect for Wehrlite vs Norite. The hardness of Wehrlite is 5.5-6 and that of Norite is 7. The types of Wehrlite are Not Available whereas types of Norite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite is white while that of Norite is black. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Norite is Not Available. 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 Norite is impact resistant, pressure resistant, wear resistant.
