The age of igneous rocks is being determined by analyzing lead content of zircon in them and at the same time by determining its a radioactivity.A spectrographic method of determining lead in zircon for the use in age determination is described.As the base and the internal standard silica and indium are used respectively with the excitation by D.C.arc.A JACO 3.4 m grating spectrograph is used, the line pairs selected are Pb (I) 2833.1 Å and In (I) 2932.6 Å.This method is applicable to samples containing lead from 5 to 1, 000 ppm with an accuracy of about 6-10 per cent in error.The accuracy was lowered to 17 per cent when the amount was as low as 1 ppm.<BR>This analytical method was applied to zircon obtained from biotite granite and granodiorite newly quarried near Nagoya and zircon samples from Korea, Formosa and Australia.Results of analysis are given.
