Volcanic rock essentially of plagioclase, labradorite, magnetite, and pyroxene, with olivine, biotite, and hornblende. Formed by magma emission. There are two distinct basalts: feldspathic and alkaline, both plagioclase feldspathics but the latter containing significantly more sodium and potassium. see nepheline-basalt and tephrite
