1 Definition
1.1 Definition
Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt
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

5 Formation
5.1 Formation
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
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.
