The deep-water region offshore NW Borneo is an active fold-and-thrust belt that hosts a signifi cant number of proven hydrocarbon accumulations. In the past, two mechanisms have been discussed as primary control for Neogene to Holocene folding and thrusting in this deep-water province: (1) basement-driven crustal shortening and (2) gravity-related delta tectonics. In this study, new, balanced interpretations of regional, crustal-scale, depth-migrated, twodimensional (2-D), multichannel seismicrefl ection profi les are presented that provide for the fi rst time quantitative data on tectonic shortening throughout the entire deep-water fold-and-thrust belt of NW Borneo. We use our tectonic restorations to compare the amount of deep-water shortening on the NW Borneo slope to the amount of extension across the NW Borneo shelf. A key result of this balancing study is the observation that Pliocene to Holocene gravity-driven shortening decreases from south to north, while the total amount of shortening increases slightly to the north. Consequently, the amount of purely basement-driven compression along NW Borneo is strongly inferred to increase toward the north. Because most of the shortening is late Pliocene and younger, we interpret the tectonic shortening to be ongoing.

Shallow marine deposits comprising the Silurian Gray Sandstone Formation (GSF) exhibit pronounced process regime changes through time. The formation was deposited on the southern shelf of the Lower Palaeozoic Welsh Basin (UK), and conformably overlies the Coralliferous Formation. The basal Lithofacies Assemblage A (of Sheinwoodian age) is dominated by a storm-dominated process regime, comprising shoreface and offshore shelf facies associations. The overlying Lithofacies Assemblage B records a mixed process regime, with units being deposited under both storm-and tide-influenced conditions. Tidal-influence prevailed during deposition of the overlying Lithofacies Assemblage C, with proximal to distal facies variations across a significant tide-influenced river delta being observed. A return to stormdominated shoreface conditions is seen in the succeeding Lithofacies Assemblage D. Lithofacies Assemblage E (Homerian age) records the return of a tide-influenced river delta to the area, prior to the conformable transition into the overlying Old Red Sandstone (ORS) Red Cliff Formation (of Ludlow age). Northward thickening of the formation across southern Pembrokeshire into the Musselwick Fault indicates a tectonic control on sedimentation, the formation infilling accommodation space developed in an intra-shelf half-graben. Recurring changes in process regime from storm-to tide-influenced sedimentation may be related to the onset and subsequent cessation of tidal resonance in subbasins across the shelf area which itself was probably controlled by episodic tectonism. It is proposed that the Coralliferous and Gray Sandstone formations comprise the newly erected Marloes Group.

Kilometre-scale synsedimentary faults associated with well-preserved sedimentary successions on both hanging-wall and footwall sides are rarely seen in outcrop. However, one such example is found in a Middle Miocene deltaic sand-shale sequence exposed along the Jerudong Anticline in onshore Brunei Darussalam. Integration of detailed outcrop information with regional geophysical subsurface data documents that: (1) initiation of the Jalan Tutong growth fault was related to delta-front instability and failure; (2) sediment loading under shallow-marine conditions maintained syndepositional faulting; (3) growth-fault abandonment coincided with a significant basinward shift of deposition and subaerial exposure. Highresolution analysis of facies characteristics, stratal expansion and throw development within the studied growth sequence indicates that differential fault movement strongly influenced facies composition, sedimentary geometry and bedding characteristics: sandstone-poor shelf to lower-shoreface successions developed during periods of rapidly increasing fault movement, whereas sandstone-rich, amalgamated upper-shoreface deposits preferentially formed during intervals of constant or decreasing throw development. The data and interpretations presented may help to focus attention on the complex interplay between tectonics and sedimentation associated with the growth and decay of deltaic faults by providing for the first time an outcropbased view on a feature documented in similar scale only by geophysical subsurface data.
