Abstract: A large and representative collection of specimens from each of the Malayan limestone formations was analysed chemically, mineralogically and petrographically in an attempt to find a criterion for differentiation independent of palaeontology. Limited success has been obtained only where the limestones are sufficiently far removed from granitic intrusions – in Perlis and Kedah, where significant lithological differences occur between limestones of different formations. Unfortunately the results cannot be extended to other areas and no generally applicable criterion for differentiation has been found.
Extensive studies of the thermoluminescence of limestones show that all collected specimens have been recrystallised during the revolutionary phase of the Thai-Malayan orogeny so that thermoluminescence cannot be used in Malaya to differentiate limestones stratigraphically.
It must therefore be concluded that the differentiation of Malayan limestones must continue to be based on fossils.
