Geochronology Of Malayan Granites

Rubidiun-strontiuo and potassium-argon age dating of the granitic rocks' of the Malny.n Peninsula show that important episodes of granites .to intrusion occurreddurine late Carboniferous (about 280 m.y), late Permian/early Triassic (abort 250 m.y.) end late Triassic (230 m.y. to 200 m.y.) times, Granites of these ages'
oonsti tute the ~1ain Range batholith, tho East Coast ba tho Lf ths, and the Gunong Benom granite in central Malaya. Small granite plutons of late Cretaceous age
'occur in Johore, Malacca and no the rn KeLantan ,

• The .granites of the East Coast region were intruded in two ep.isodOC at 250
Pl•Y, and ,220 m.y. (Rb: Sr isochrons )*. K:Ar ages on mtcas are generally concordant,
- with the appropriate Rb:Sr isochron age , In southern Malaya and Singapore granite; intrusion appears to be restricted to a 220 Ill•Y• event. Mien K:J.r ages are generally .concordant with the isochron age.
