Definition

Enderbite rock is an igneous rock which belongs to the Charnockite rock series

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

Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

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.
