Eight types of seismic facies were identified, which are parallel to subparallel, wavy, mounded divergent, divergent fill, progradational, stratified high-amplitude, chaotic high-amplitude, and transparent facies, respectively. Sedimentological interpretation of the seismic facies indicates that the deep-sea basin has not always been tranquil as imagined, large-scale sediment waves, overbank deposits, turbidity-current channel and levee deposits, and submarine fan lobes are developed. The gravity-flow deposits are mostly distributed temporally in the upper Miocene and Quaternary sequences and spatially in the northwestern, northern and eastern parts of the basin.Presentation Date: Tuesday, October 16, 2018Start Time: 1:50:00 PMLocation: 210A (Anaheim Convention Center)Presentation Type: OralKeywords: seismic stratigraphy, turbidite, facies, 2D, deepwaterPermalink: https://doi.org/10.1190/segam2018-2997670.1FiguresReferencesRelatedDetails SEG Technical Program Expanded Abstracts 2018ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2018 Pages: 5520 publication data© 2018 Published in electronic format with permission by the Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 27 Aug 2018 CITATION INFORMATION Biwen Wang, Guangfa Zhong, Liaoliang Wang, and Yiqun Guo, (2018), "Types and characteristics of seismic facies in the northern South China Sea Basin," SEG Technical Program Expanded Abstracts : 1590-1594. https://doi.org/10.1190/segam2018-2997670.1 Plain-Language Summary Keywordsseismic stratigraphyturbiditefacies2DdeepwaterPDF DownloadLoading ...
