Abstract: The Upper Eocene to Pleistocene sedimentary sequence in Sarawak has been subdivided into eight sedimentary cycles separated by rapid and widespread transgressions. Although cycles are recognised on the basis of depositional environments, it is necessary that they are dated and correlated by biostratigraphic methods for consistent identification.

The recognition of these sedimentary cycles has provided a stratigraphic framework for regional correlation and facies mapping and thus has contributed to the geological evaluation of the Sarawak basin.
