Rocks can be described as having more than one texture as long as the texture types are not mutually exclusive. The composition of Scoria can vary depending on its location of formation, with some samples containing up to 60% silica by weight. Foamlike scoria, in which the bubbles are very thin shells of solidified basaltic magma, occurs as a product of explosive eruptions (as on Hawaii) and as frothy crusts on some pahoehoe (smooth or billowy-surfaced) lavas.
