Definition

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

During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation

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

Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.
