Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

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.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Wehrlite vs Granulite 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 Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Granulite. Learn more about Wehrlite vs Granulite in the next section. The interior uses of Wehrlite include Decorative aggregates and Interior decoration whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Wehrlite and Granulite, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Granulite include As dimension stone, Building houses or walls.
More about Wehrlite and Granulite
Here you can know more about Wehrlite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Granulite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Granulite, 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, Granulite is available in black, brown colors. Appearance of Wehrlite is Rough and Banded and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Wehrlite vs Granulite. The hardness of Wehrlite is 5.5-6 and that of Granulite is 6-7. The types of Wehrlite are Not Available whereas types of Granulite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Granulite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Granulite is 0.14 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 Granulite is heat resistant, wear resistant.
