Abstract

ABSTRACT

The western flank of the Jerudong Anticline, onshore Brunei Darussalam, provides a rare opportunity to analyse the base of a major Miocene mud‐rich delta in outcrop, including kilometre‐scale prograding clinoforms, delta‐front turbidites and large‐scale syndepositional faults. The lateral continuation of this system in the subsurface of the Belait Syncline is documented on two‐dimensional (2D) reflection seismic data and wireline logs. In order to link geological observations at surface with corresponding geophysical subsurface signatures, we constructed a combined, quantitative 3D surface–subsurface model of onshore Brunei Darussalam. This 3D model is used to analyse and discuss the relation between field geology and geophysical subsurface interpretation, and provides the base for a quantitative kinematic restoration of the Miocene Belait delta to its original shape before folding. Final decompaction of the balanced rock volume allows the reconstruction of the palaeo‐relief of a series of Miocene clinoforms, indicating a close relation between delta‐lobe activity, clinoform morphology and the generation of delta‐front turbidites.
