Scoria and Granodiorite

Scoria

Granodiorite

Definition

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

Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite

Formation

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

Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.
