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
  
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

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.
  
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

More about Adakite and Boninite
Here you can know more about Adakite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adakite and Boninite consists of mineral content and compound content. The mineral content of Adakite includes Olivine, Plagioclase, Pyroxene and mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Adakite vs Boninite, 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, Boninite is available in bluish - grey, brown, colourless, green, grey colors. Appearance of Adakite is Dull and Soft and that of Boninite is Dull and Soft. Properties of rock is another aspect for Adakite vs Boninite. The hardness of Adakite is 3-4 and that of Boninite is 7. The types of Adakite are Not Available whereas types of Boninite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface.
