Abstract: Data from some 88 wells in the Luconia and Balingian provinces was used to unravel the palaeobathymetrical history of NW Sarawak from Oligocene to Pliocene times. A comparison of the Sarawak palaeobathymetrical curve with the global sea-level curve suggests that from Middle Miocene to Pliocene times changes in bathymetry were largely controlled by eustacy, while during the Late Oligocene to Early Miocene the effect of global sea-level changes was largely masked by important tectonic movements.
