Definition

Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities

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

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

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.
