Sequence stratigraphic framework of Northwest Borneo

The character of the Cenozoic sedimentary sequence of NW Borneo exhibits the interplay of eustatic sea level change and the commonly dramatic effects of tectonic events. In this paper, we show how the adoption of a unified stratigraphic nomenclature, tied to the Global Sequences of Haq et al. (1988), can help unravel the superimposition of eustatic and tectonic processes. We also assess the importance of these processes in terms of the genesis, character and the distribution of the basin fills. The results give us a greater understanding of the key exploration plays in the region and a framework to link the play elements.
