Abstract: The K-Ar data indicate that in East Pahang and Trengganu there have probably been episodes of basic igneous activity during the Jurassic, Cretaceous and Pleistocene. The potassium-rich lavas of Segamat, Johore are at least early Palaeocene in age. A late Miocene age was given by a basalt from Ko Kut, an island in the Gulf of Thailand.
