'''Gadolinite''', sometimes known as '''ytterbite''', is a [[silicate mineral]] consisting principally of the silicates of [[cerium]], [[lanthanum]], [[neodymium]], [[yttrium]], [[beryllium]], and [[iron]] with the formula {{chem2|(Ce,La,Nd,Y)2FeBe2Si2O10}}. It is called gadolinite-(Ce) or gadolinite-(Y), depending on the prominent composing element (Y if yttrium predominates, and Ce if cerium). It may contain 35.5% yttria sub-group rare earths, 2.2% ceria earths, as much as to 11.6% BeO, and traces of [[thorium]]. It is found in Sweden, Norway, and the US (Texas and Colorado).
