If this happens deep underground, they are intrusive igneous rocks. Most igneous rocks have a crystalline texture, but some are clastic, vesicular, frothy, or glassy. Volcanic tuffs have the same origin as volcanic breccias - explosive volcanic eruptions. Volcanic tuffs lack the abundance of large, angular grains present in volcanic breccias (although I
