Definition
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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.

Metapelite 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. Metapelite vs Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Metapelite and Properties of Granulite. Learn more about Metapelite vs Granulite in the next section. The interior uses of Metapelite 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 Metapelite and Granulite, they have various applications in construction industry. The uses of Metapelite in construction industry include Cement manufacture, Construction aggregate, For road aggregate and that of Granulite include As dimension stone, Building houses or walls.
More about Metapelite and Granulite
Here you can know more about Metapelite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Granulite consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz 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 Metamorphic Rocks. When we have to compare Metapelite vs Granulite, the texture, color and appearance plays an important role in determining the type of rock. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas, Granulite is available in black, brown colors. Appearance of Metapelite is Banded and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Metapelite vs Granulite. The hardness of Metapelite is 5-6 and that of Granulite is 6-7. The types of Metapelite are Metamorphic rock whereas types of Granulite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Metapelite is while that of Granulite is white. The specific heat capacity of Metapelite is 0.72 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.Metapelite is heat resistant, impact resistant, pressure resistant whereas Granulite is heat resistant, wear resistant.
