Quaternary stratigraphy of Hong Kong coastal sediments

Coastal Quaternary morphologies on the northern coast of the South China Sea, China, and their implications for current tectonic models: A review and preliminary study

“…Zong, 2004) compared to Taiwan (Liew et al, 1990(Liew et al, , 1993Liew and Hsieh, 2000;Chen andLiu, 1996, 2000;Chen et al, 2004;Hsieh et al, 2004;Song et al, 2004;Yamaguchi and Ota, 2004), Hong Kong (Owen, 1995;Davis, 1999Davis, , 2000Yim, 1999;Fyfe et al, 2000, Yim and Huang, 2002Baker et al, 2003;) or South Korea (Kim and Lee, 2006). For the southern Fujian province, Xie et al (1985) stated that sea level fluctuated from 8000 to 7000 yr B.P.…”

Sedimentary development of the Pearl River Estuary based on seismic stratigraphy

“…The stage of regression could be linked to the last glacial period and the sea level fall (Huang, et al, 1982). is evidently not present in the part of Hong Kong waters which may depend on whether or not alluvial deposition occurred during low sea level stands of the glacial periods (Davis, 1999).…”

“…Bathymetry was extracted partly from the navigation map and partly from the seismic profiles. The presence of gas especially in the west part of PRE, greatly attenuates seismic signals causing acoustic shield where large tracts of the sea floor are rendered acoustically impenetrable (Davis, 1999;Xia et al, 2006). Semi-transparent and elliptic polygons in Fig.…”

“…Such a fact is supported by evidence in core NZ2 that section A is prior to 20 ka BP. This time period was almost equal to Marine Isotope Stage (MIS) 3 stage, which is widely considered as a stage of transgression on the delta in Late Pleistocene Table 1 Summary of main evolutionary steps recorded in the sedimentary infill of the Pearl River Estuarine surrounding area with comparison to Pearl River Delta (Huang et al, 1982) and Hong Kong waters (Davis, 1999 (Huang et al, 1982;Lan, 1991;Long, 1997). However, there are still many arguments about the transgression age, because the global sea level was about 40-60 m below present in MIS3 (Lambeck and Chappell, 2001).…”

“…Regarding with geology, many authors (e.g. Long, 1997;Davis, 1999;Liu et al, 2004;Owen, 2005;Yim et al, 2006) have studied the Late Quaternary deposits in the Pearl River Delta and northern South China Shelf using seismic reflection profiling and borehole data, but few PRE records have been addressed about Holocene sedimentary environment change. In particularly, the sedimentary history of the estuarine filling is still poorly understood, especially referring to effects of late Pleistocene sea level fluctuations on the preservation potential of depositional sequences.…”
