Definition
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

Features
Has High structural resistance against erosion and climate, Host rock for Diamond, Very fine grained rock
Available in Lots of Colors and Patterns, It is One of the Oldest, Strongest and Hardest Rock
Archaeological Significance
Formation
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

More about Adakite and Enderbite
Here you can know more about Adakite and Enderbite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adakite and Enderbite consists of mineral content and compound content. The mineral content of Adakite includes Olivine, Plagioclase, Pyroxene and mineral content of Enderbite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Adakite vs Enderbite, the texture, color and appearance plays an important role in determining the type of rock. Adakite is available in black, brown, light to dark grey colors whereas, Enderbite is available in black, grey, orange, pink, white colors. Appearance of Adakite is Dull and Soft and that of Enderbite is Veined or Pebbled. Properties of rock is another aspect for Adakite vs Enderbite. The hardness of Adakite is 3-4 and that of Enderbite is 6-7. The types of Adakite are Intermediate volcanic rock whereas types of Enderbite are -. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Adakite is bluish black while that of Enderbite is white. The specific heat capacity of Adakite is 0.84 kJ/Kg K and that of Enderbite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Adakite is heat resistant, pressure resistant, wear resistant whereas Enderbite is heat resistant, wear resistant.
