“…The sublacustrine fan that spilled over from the delta front in the accommodation zone area is characterised by subaqueous gravity-flow deposits. Different from the traction current, the pathway of this kind of gravity-flow is usually greatly influenced by topography (Benvenuti, 2003;Athmet et al, 2010;Moernaut and De Batist, 2011). This is consistent with the experimental study by Athmer et al (2010) showing that the prevalent basin-ward tilt of transfer zones can direct unconstrained subaqueous gravity flows directly into a basin.…”

The up per part of the Lower Mio cene Sloboda Con glom er ate, a 250-1400 m thick unit, was de pos ited mainly on an al lu vial fan and fan delta dur ing the early stages of Carpathian Foredeep de vel op ment. Dur ing of the Old Styrian overthrust move ments of the Carpathian orogen, a forebulge was formed, which sup plied clasts to the con glom er ate. The clasts are dom i nated by Late Pro tero zoic-Early Cambrian phyllites, while Pa leo zoic car bon ates are com mon, and Me so zoic and other rocks are rare. The source area formed mainly by a prolon ga tion of the Małopolska Mas sif that was in volved in the forebulge; this was lo cated close to a palaeovalley cut into Me so zoic and Pa leo zoic rocks, bur ied un der youn ger strata. Ad di tional ma te rial was de rived from the ad vanc ing front of the Carpathian Flysch nappes.

“…The sublacustrine fan systems are basically formed in passive margin settings (Stelting et al 2000), e.g., Amazon Fan in Brazil (Damuth and Kumar 1975), Mississippi Fan in Gulf of Mexico (Moore et al 1978), West Africa, and North Sea, and usually deposited in the basin margins. The sedimentary architecture and geographical features of the sublacustrine fan systems are very useful in basin analysis, as they record the tectonic evolution and the sedimentary processes during the formation of these sediments (Benvenuti 2003;Leeder et al 2002;Mata and Bottjer 2013;Rajchl et al 2008).…”

Fine-grained and coarse-grained Paleogene sublacustrine fan systems in Fushan Depression, Beibuwan Basin, South China Sea: implications for sedimentary characteristics and depositional processes

et al. 2016

The Fushan Depression is a hydrocarbon-bearing half-graben rift sub-basin located in the southeast of the Beibuwan Basin, South China Sea. The sublacustrine fan systems in the Paleogene Liushagang Formation have recently become important targets in this depression, while the depositional process and detailed characterization of these systems are little known. Analysis of drilled cores, wire-line logs, and 3-D seismic survey suggest that the Fushan Depression develops two different types of sublacustrine fan systems. The fine-grained sublacustrine fan system located in the western area is mainly composed of fine-to medium-grained light gray sandstones interbedded with layers of silt-rich shales. This kind of sediment slumped from the distal bar of the delta front due to high sediment pore pressures at the slope edge as well as the activity of the Meitai Fault. By contrast, the coarsegrained sublacustrine fan system formed in the eastern area is characterized by medium to coarse gray sandstones and conglomerates with the development of various deformed lenticular beddings, deformed pillow structures, and micro-faults. Further study suggests that its sedimentation process is closely related to the geomorphology of flexure slope-break belt. The slope changed abruptly from 3°~5°to 7°~9°across the flexure slope point, increasing the accommodation space under the flexure belt. The coarse-grained sublacustrine fan formed when coarse-grained sediment spillover the slope-break toward the increased accommodation space. As the reservoir quality of these sublacustrine fan systems is well controlled by the sedimentary characteristics and sedimentation processes, our results should be of great significance for the development of future exploration.
