scoria

scoria Loose, rubbly, basaltic ejecta that accumulate around Strombolian eruptive volcanic vents, eventually building up as a scoria cone, whose height may range from a few tens of metres to up to 300 m, and whose slope is determined by the angle of repose of the loose material. The scoria clasts range widely in size, and have a light, frothy texture, being full of vesicles. They are mainly drab grey in colour, although when fresh they may be iridescent, but often the scoria oxidizes by reaction with steam escaping from the vent, when it becomes a deep reddish brown.
