Outcrop Analogues of Deepwater Depositional Systems: A Comparative Study of Turbidite Sequence from Malaysia

Summary This study focused on the three most famous deep water outcrops and depositional systems in Malaysia, namely West Crocker, Semantan and Semanggol Formations in the states of Sabah, Pahang and Perak, respectively. The sedimentological characteristics and geological controls on the depositional systems of these deep water deposits will be cross-examined and discussed in this paper. These three main submarine fan systems are deposited by the progradation, retrogradation and lateral migration of deep, shallow channels & distributary channels and channelised & non-channelised & distal lobes depositional elements in a large elongate basin-floor. It must be comprised of several small deep water fan lobes due to multiple existences of several same types of depositional elements and multidirectional palaeocurrent directions in a wide range of sub-environments from proximal to distal depositional environments of slope to inner to mid and to outer fan settings. The study has provided new insight into understanding of the productive turbidite depositional systems and as partial analogue for deep water reservoirs in offshore Malaysia and South East Asia areas.
