“…This unconformity surface is defined as the sequences boundary (SB1). The SB1 surface on the shelf in the Gulf of Tonkin could be similar to the SB1 surface determined on the SE Vietnam Shelf and the Sunda Shelf that was defined by Dung et al (2013), Thanh (2017), and Hanebuth et al (2011). In the nearshore area, the depth of SB1 is approximately 25-30 m below the present sea-level and it deepens seaward.…”

“…The transgressive surface was named alternatively such as 'initial transgressive surface' ITS (Nummedal et al, 1993) and had been established in the early period of sea-level rise after the lowstand sea-level. The transgressive ravinement surface (TRS) was named alternatively such as RS in a number of researches (Dung et al, 2013;Yoo et al, 2014 etc.). The transgressive ravinement surface (TRS) had been generated by strong marine erosion of waves and littoral currents in the coast and shallow-water settings.…”

“…Application of sequence stratigraphy has been used for numerous continental shelves to increase deep insights to the history of late Pleistocene-Holocene sedimentary evolution in relation to the global sea-level change. A significant amount of high resolution seismic data collected on the modern continental shelves facilitates for applying the sequence stratigraphy theories (Boyd et al, 1992;Saito et al, 1998;Hanebuth et al, 2004;Dung et al, 2013;Yoo et al, 2014;Thanh, 2017 etc. ).…”

The model of Late Pleistocene-Holocene sequence stratigraphy of the subaqueous Red River delta and the adjacent shelf is proposed by interpretation of high resolution seismic documents and comparison with previous research results on Holocene sedimentary evolution on the delta plain. Four units (U1, U2, U3, and U4) and four sequence stratigraphic surfaces (SB1, TS, TRS and MFS) were determined. The formation of these units and surfaces is related to the global sea-level change in Late Pleistocene-Holocene. SB1, defined as the sequence boundary, was generated by subaerial processes during the Late Pleistocene regression and could be remolded partially or significantly by transgressive ravinement processes subsequently. The basal unit U1 (fluvial formations) within incised valleys is arranged into the lowstand systems tract (LST) formed in the early slow sea-level rise ~19-14.5 cal.kyr BP, the U2 unit is arranged into the early transgressive systems tract (E-TST) deposited mainly within incised-valleys under the tideinfluenced river to estuarine conditions in the rapid sea-level rise ~14.5-9 cal.kyr BP, the U3 unit is arranged into the late transgressive systems tract (L-TST) deposited widely on the continental shelf in the fully marine condition during the late sea-level rise ~9-7 cal.kyr BP, and the U4 unit represents for the highstand systems tract (HST) with clinoform structure surrounding the modern delta coast, extending to the water depth of 25-30 m, developed by sediments from the Red River system in ~3-0 cal.kyr BP.

“…The quasi‐pure hematite composition observed in the Mekong River and in Borneo, for example, is not found in the surface marine sediments of the southern basin. This emphasizes the role played by the wide and shallow continental shelves in the sequestration of a significant part of the river sediments (Clift, ; Duc et al, ; Dung et al, ; J. Liu et al, ; Steinke et al, ; Szczuciński et al, ). In the southernmost part of the SCS, magnetite‐rich sediments originating from the basaltic rocks in Sumatra are also trapped on the Sunda shelf as they obviously do not reach the SCS basin.…”

More than 650 Mt/year of fluvial sediment are delivered from continental regions into the South China Sea (SCS). Previous studies have shown that the composition of the magnetic fraction of riverine sediments drained into the SCS is significantly variable from north to south. On the basis of this evidence, we now examine a full set of magnetic properties for a number of core tops taken at water depth of mostly between 800 and 3,500 m. Room temperature magnetic parameters and thermal spectra are used to obtain information about the concentration and mineralogical magnetic composition. Spatial changes are observed in the relative proportion of magnetite and hematite with an increase of the latter toward the south, similarly to the observation on land. However, the N‐S contrast is much weaker in marine core tops than in river sediments, because of the role played by the shelf in partly trapping river‐borne sediments, in particular in the southern SCS. In part, sediments also reach the continental slope and the deep basins, being transported and mixed by surface and deepwater currents, which yield the magnetite‐hematite mixing in the south. For the first time, we characterize a wide spectrum of magnetic properties of modern marine sediment in the SCS. Our results give important insights into the modern pathways of sediment particles, depicting the source‐to‐sink processes that affect the terrigenous sediment load.
