Definition

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

Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz

Formation

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

Adamellite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma and is a variety of Monzogranite.
