Interactions Between Depositional Regime and Climate Proxies in the Northern South China Sea Since the Last Glacial Maximum

“…(2009), and data from East of Pearl River (EPR) from J. G. Liu et al. (2019). Data from ODP Site 1144 from Hu et al.…”

“…The supply of illite and chlorite from Taiwan is the product of rainfall‐driven erosion, while the supply of smectite from Luzon depends on both rapid chemical weathering and physical erosion (Z. Liu et al., 2009). In addition, the weathering of volcanic rocks under a hot humid climate in the EPR area can also generate smectite (J. G. Liu et al., 2019). Therefore, the smectite/(illite + chlorite) ratios in Core F07 can be taken to indicate changes in the monsoon precipitation in Luzon and/or South China (Figure 6c).…”

Effect of Sea-Level Change on Deep-Sea Sedimentary Records in the Northeastern South China Sea over the past 42 kyr

“…At around 14 kyr, both low sea-level condition and rising temperature of seawater were responsible for dissociating the 6 Geofluids hydrated reservoirs, which subsequently led to the release of gas and slope failure, and the contemporaneous turbidity current began to form. During the early stage of the turbidity current formation, plenty of materials were transported from the parent location to deep sea along the steep slope.…”

“…Among various fluvial drainage systems, the mountainous rivers from southwestern (SW) Taiwan discharge the largest number of suspended sediments directly to the SCS, with a total load of 176 Mt/year, South China contributes about 102 Mt/year, and the supply from Luzon Island is more than 13 Mt/year ( Figure 1) [3]. Recently, the area in the east of the Pearl River (EPR) has been considered as another potential source for sediment supply to the northern SCS [6]. These fluvial sediments are further transported by various coastal, surface, and deep currents after entering the SCS, such as the East Asian monsoon (EAM), which is the major control on the surface circulation.…”
