Bastnaesite, CeFCO 3 , is a secondary mineral formed by alteration of monazite, and contains La replacing Ce. Its cell dimensions are a 7.09(1), c 9.78(8) Aa. The leaching of Ce and La from monazite, with concentration in nearby fractures, provides an example of the retardation of radionuclide migration from potential nuclear waste disposal sites in crystalline rocks.--Modified journal abstract.
