Abstract
The Lingan fan system in a toe-thrust foldbelt area is a unique example of mass transport complexes (MTCs) in a channelised fan located on the steep, tectonically active NW Borneo margin, connected to a series of main slope feeder channel complexes.These thrust-related growth folds and their syn-depositional topographic features represent a major control on sedimentary pathways and stratigraphic development of these gravity flow deposits in the slope and basin floor areas.Seismic stratigraphic and facies analysis combined with attribute interpretations of the three-dimensional seismic data volume are used to study the temporal and spatial distribution and stratigraphic development of mass transport complexes (MTCs) in slope and basin floor deposits of the Lingan fan system.The analysis shows how the temporal and spatial distribution of the deepwater facies and stratigraphic development of such syn-depositionally deposits are influenced by the prominent syn-kinematically thrust-related growth folding structures in the study area. The study provides a better understanding of temporal and spatial distribution and stratigraphic development of MTCs in the slope and basin floor of the mixed sand-mud Lingan fan system. Also, the results reveal how significant is the influence of syn-kinematically thrust-related growth folding to the stratigraphic development of the deposits.
