Abstract:
Valley incision and infilling, as well as the fluvial response of uppermost Pilong formation in Penyu Basin located offshore of present-day Pahang River Basin, Peninsular Malaysia during Late Pleistocene-Mid Holocene was studied. A detailed study of time slices, horizon surfaces and vertical sections of three-dimensional (3D) volume data, high-resolution two-dimensional (2D) CHIRP acoustic profiles, and seabed bathymetric data provided a very good opportunity to delineate the changes of the deglacial fluvial pattern as well as its internal morphology and its evolution through geologic time. Based on the fluvial origin, plan-view pattern and internal architecture, six classes of deglacial fluvial sequences have been categorized.
