Landscape Analysis of Borneo

This Regional Report analyses the Present Day drainage and landscape in order to identify evidence for past changes in the river networks and in the surface morphology. Assessing the impact of tectonics and surface processes on the evolution of the landscape helps predict the grain size, type and distribution of sediments into the offshore basins.

The key products of the study are the location of palaeorivers, which carried the sediments into the coastal basins. Pivotal elements from our Structure and Tectonics of Southeast Asia report, based on Getech’s Global Plate Model for the region, have been used as a framework in which we have placed our interpretations.

This Regional Report investigates…

…the provenance areas of rivers that have affected deposition in the Baram and Champion Deltas.

…whether the Padas River captured or antecedent, or even a combination of the two.

…how the Mahakam River and its evolution have influenced offshore deposition.

…other specific provenance areas in Borneo known to have provided sands to depositional areas.

…the turbidite sequences from the West Crocker Formation (the Crocker Fan), and whether they are derived from the Schwaner Mountains?
