Physical properties
Reddish-brown color, vesicular texture (containing holes), relatively lightweight, rough and porous surface.
Formation & geological history
Formed from cooling of gas-rich lava, typically mafic (basaltic) in composition. Found in volcanic areas.
Uses & applications
Used in landscaping, construction (as aggregate), and sometimes in gas grills.
Geological facts
Scoria is often referred to as 'lava rock' in landscaping contexts.
Field identification & locations
Easily identified by its dark or reddish color and highly vesicular texture. Common in areas with past basaltic volcanism.
