10 trace elements; Co, Cr, Sc, Rb, Cs, Ba, Hf, Th, U and Ra, have been determined on the rocks and the separated minerals from the Ibaragi granitic complex.The distribution of these elements in the complex is qualitatively understood by fractional crystallization.Cs is deficient in amount at the later stage of the fractionation, and is supposed to be removed from the rocks to a gaseous phase or hydrothermal water.U is in radioactive equilibrium with Ra in the complex.
