Formation

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 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.

More about Granulite and Wehrlite

Here you can know more about Granulite and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Wehrlite consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Wehrlite is available in dark greenish - grey, green colors. Appearance of Granulite is Veined or Pebbled and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Granulite vs Wehrlite. The hardness of Granulite is 6-7 and that of Wehrlite is 5.5-6. The types of Granulite are Metamorphic rock 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 Granulite and Wehrlite is white. The specific heat capacity of Granulite is 0.14 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.Granulite is heat resistant, wear resistant whereas Wehrlite is heat resistant, impact resistant, pressure resistant.
