Definition
Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

Formation
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.
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.

Anorthosite 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. Anorthosite vs Wehrlite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Wehrlite. Learn more about Anorthosite vs Wehrlite in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Wehrlite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Anorthosite and Wehrlite, they have various applications in construction industry. The uses of Anorthosite in construction industry include As dimension stone, Cement manufacture, For road aggregate and that of Wehrlite include As dimension stone, Cobblestones.
More about Anorthosite and Wehrlite
Here you can know more about Anorthosite and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Wehrlite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas, Wehrlite is available in dark greenish - grey, green colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Anorthosite vs Wehrlite. The hardness of Anorthosite is 5-6 and that of Wehrlite is 5.5-6. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Wehrlite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite and Wehrlite is white. The specific heat capacity of Anorthosite is 0.84 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.Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant whereas Wehrlite is heat resistant, impact resistant, pressure resistant.
