A large bastnasite deposit was discovered at Mountain Pass, Calif. Subsequent development of the deposit made the United States the world's largest source of rareearth minerals. Since then, bastnasite, a fluocarbonate of the ceriumgroup metals, REFCO3, has replaced monazite as the principal source of rare earths; in 1978 it accounted for more than half of the world production.
