Abstract: The results of Rb/Sr age determination work on 6 whole rock samples of the granite in the Kuantan area together with K-Ar data on biotite separates are reported. The whole rock data plotted on an isochron 292 ± 12 m.y. with an initial 87Sr/86Sr ratio of 0.704. K-Ar data from the biotites gave discordant ages.

K-Ar dating of whole rock samples from 6 dolerite dykes intrusive into the granite gave ages of about 100 m.y. except one sample which gave an age of 131 m.y.
