1 INTRODUCTION

Shelf mud deposits can be found on continental shelves worldwide, mainly on shelves with abundant terrestrial sediment supply and often in the form of elongated mud belts distributed along the coastline(Gao and Collins, 2014). The formation of mud deposits in shallow water is mostly associated with river input (Wang et al., 2014), such as the large shelf mud deposits associated with the Amazon River(Anthony et al., 2010), the Changjiang (Yangtze)River (Xu et al., 2012), the Huanghe (Yellow) River(Liu et al., 2007) and the Po River (Niedoroda et al.,2005). These Holocene deposits are 30–50 m thick.Other examples include shelf muds associated with the Niger (Riboulot et al., 2012), the Mekong (Tamura et al., 2012), the Red (van Maren, 2005), the Zhujiang(Pearl) (Owen, 2005), the Keum (Lee and Chu, 2001),the Eel (Curran et al., 2002), and the Waipaoa (Gerber et al., 2010) rivers.

The mud deposits that wrap around the end of the Shandong Peninsula in the Yellow Sea has been discussed in detail since it was first noted in the 1980s(Qin and Li, 1986; Milliman et al., 1989; Qin et al.,1989b; Alexander et al., 1991; Cheng et al., 2001; Liu et al., 2002, 2004, 2007; Yang and Liu, 2007). The proximal and distal phases of clinoform development were identified by Liu et al. (2002, 2004) in terms of the distance between the Huanghe River mouth and the clinoform during the postglacial transgression.Recent studies have revealed a unique Huanghederived, alongshore distributed, bidirectional(landward and seaward) across-shelf transported,omega-shaped (“Ω”) distal subaqueous deltaic lobe deposited around the eastern tip of the Shandong Peninsula and shown the detailed isopach of the Holocene sediments (Yang and Liu, 2007), and stratigraphy and environmental changes during the Holocene off the northern Shandong Peninsula (Liu et al., 2007). Qiu et al. (2014) reported the existence of a Holocene subaqueous clinoform off the southern Shandong Peninsula, which is distributed along the coastline in bands and in fan shapes at the mouths of some bays.

双方对峙了一会儿，一只冥河盗龙突然从侧面冲了上来，看来它是想冒险打破僵局。反应迅速的肿头龙注意到了冥河盗龙的动作，它马上低着头冲了过来。眼看双方就要撞到一起了，这时，冥河盗龙一下子跳了起来，后腿努力向前伸出，想用脚上锋利的镰刀爪刺伤肿头龙。只听“咚”的一声闷响，紧接着发出一阵尖厉的叫声。原来冥河盗龙不仅没有伤到肿头龙，自己反而被撞了出去，重重地摔落在树丛中。由于强大的惯性作用，肿头龙又向前跑了好几步才停下来，它喘着粗气，身上的肌肉仍然紧绷着，随时准备撞击下一个目标。看到自己的同伴被肿头龙撞飞，就连骨头断裂的声音都清晰可辨，其他冥河盗龙退缩了，它们可不打算赔上自己的性命，一个个灰溜溜地逃走了。

Despite these studies, our knowledge of the mud deposits off the southern Shandong Peninsula has been limited, especially about how these deposits link together. There are only a few profiles in the Jinghai Bay area (Fig.1b, blue lines), where a subaqueous delta (Yang and Liu, 2007) combines with a subaqueous clinoform (Qiu et al., 2014), so the actual distribution and architecture of mud deposits in this area remain unclear. In this paper, we discuss the high-resolution seismic structure of the Yellow Sea off the Shandong Peninsula, as well as other sedimentological and oceanographic data, which collectively allow us to examine the provenance and history of these mud deposits. These results will be of great significance to reveal the sources and sinks,interactions between land and sea, paleoenvironmental evolution in response to the sea level changes

2 PHYSICAL SETTING

The Yellow Sea is a shallow, post-glacially submerged epicontinental sea above a flat, tectonically stable shelf with water depth is no more than 100 m(Fig.1a). The South Yellow Sea reaches about 700 km in width and deepens toward the Yellow Sea Trough,defined by the 80 m isobath that is oriented NW-SE(Qin et al., 1989b). The floor of the western part of the South Yellow Sea is made up of four geomorphologic units from north to south: the Shandong mud wedge(Liu et al., 2004, 2007); an erosional area south of the Shandong Peninsula; the Old Huanghe River Delta,an abandoned subaqueous delta formed between 1128 and 1855; and the Jiangsu radial tidal sand ridges.

The Holocene mud deposit from core WHZK01 can also be divided into the upper unit and the lower unit by the MFS (Fig.8). The upper unit is mainly composed of gray clayey silt and silt and the lower unit is mainly composed of gray-yellow silt sand and clayey silt (Liu, 2016).

The modern Huanghe River presently discharges into the western Bohai Sea, and its sediment can be transported into the North and South Yellow Sea by coastal currents. The course of the Huanghe River has changed frequently during the Holocene, and in a period from 1128 to 1855 AD, the river shifted south of the Shandong Peninsula and discharged into the South Yellow Sea (Zhang, 1984).

3 MATERIAL AND METHOD

During the middle Holocene, about 6.5 kyrs, the Yellow Sea Warm Current and the modern circulation pattern formed (Liu et al., 1999; Li et al., 2007),sediments from rivers on the Shandong Peninsula poured into Jinghai, Rushan, Dingziwan, Aoshan, and Xiaodao bays, formed sedimentary fans at their mouths. At the same time, sediments were influenced by coastal currents that carried Huanghe Riverderived sediments to this area, as evidenced by sediment geochemistry of core QDZ03 (Qiu et al.,2014) and the surface sediments (Zhang et al., 2014)(Fig.7). Besides, comparison of heavy minerals, clay minerals and XRF scanning elements among the sediment of the core WHZK01, the surface sediment from Rushan River, Qinglong River and Huanghe River-derived sediment also suggest that the provenance of the upper unit is the joint contribution from the local small rivers and Huanghe River (Liu,2016). Suspended sediment concentrations along the Shandong Peninsula can also verify plume transport from the Bohai Sea to the Yellow Sea (Qin et al.,1989a; Martin et al., 1993). All of these comprise sources of the upper unit of the nearshore deposit.

According to the AMS 14 C dates of cores QDZ03 and WHZK01 (Figs.7 and 8), the lower unit of the deposit formed between 11 and 9 kyrs, which agrees with the formation time of the proximal sequence of the Shandong subaqueous clinoform (Liu et al.,2004). From about 11.6 to 11.3 kyrs, sea level jumped from about -58 m to -43 m in response to the Meltwater Pulse (MWP)-1B event (Liu et al., 2004), which was followed by stagnating sea level rise (from -42 m to-38 m) for about 1.8 kyrs (Fairbanks et al., 1989). We suggest it was during this period 1.8-kyrs interval(11–9.2 kyrs) of slow-rising sea level and increased local rivers and Huanghe River discharge that the lower unit of the deposit accreted over the transgressive surface. When the transgressive surface initially formed around 11 kyrs, the sea level stood at about-40 m (Liu et al., 2004), where maybe the location of the local rivers mouth, so the sediments from local rivers on the Shandong Peninsula can be emptied into sea directly, combined with the proximal sediments from Huanghe River, formed the lower unit of the off shore deposit. Beginning 9.8 kyrs, sea level again rose rapidly, from 36 to 16 m in 800 years. When the nearshore area was merged gradually and the lower unit of the nearshore deposit was formed in a subtidal environment. Because of the landward of local small rivers mouth and the Huanghe River diverted to the Jiangsu coast south of the Shandong Peninsula, the sedimentation rate was relatively low.

A borehole core (QDZ03), 40.20 m in length, was obtained on the seismic line by the rigging method(Fig.1b) in May 2011 by drilling vessel Kan 407. The core site (36°16′03.21″N, 120°56′58.77″E) is located in muddy sediment at a water depth of 15.50 m.Recovery of mud-dominated sediments in the core was over 87% on average; recovery of the reaming intervals was generally 60% to 90%. In the laboratory,the core was split, described and subsamples. AMS 14 C dating was conducted on molluscan shells and foraminiferal tests using accelerator mass spectrometry (AMS) on equipment from Beta Analytic Inc. (Miami, FL, USA; Qiu et al., 2014).

在农业技术的推广过程中，由于资金投入的不足，导致农业技术的推广受到很大的阻碍。从数据上来看，发达国家在农业技术推广中投入的经费远远大于我国，其在农业总产值中所占的比例为0.6%-1.0%。即使是发展中国家，农业技术推广经费在农业总产值中所占的比例也有0.5%左右，而我国在这方面的投入还不到0.2%。在这样的情况下，人均经费多么的不足便可想而知。经费的不足，导致农业技术的推广十分被动，很难将新技术有效地运用到农业生产中，这也是我国农业发展缓慢的一个重要原因。

The green lines represent newly acquired profiles; the black profiles and core QDZ03 were collected from Qiu et al. (2014); Core WHZK01 was collected from Liu et al. (2016); the blue lines are profiles from Yang and Liu (2007). Solid circles are the location of surface sediment samples. The red circles represent the location of the cores QDZ03 and WHZK01. Heavy green lines denote the selected profiles in Figs.2–4.

The lower unit of the nearshore deposit is usually less than 3 m in thickness and formed under a low sedimentation rate. It exhibits basal onlap and is overlaid by discontinuous subparallel reflectors. The upper unit of the nearshore deposit is characterized by progradation seaward with inclined internal reflectors dipping to the south and east (Fig.2). The isopach map of the nearshore deposit shows bands paralleling the coastline from Jinghai Bay to Laoshan Head(Fig.5). At the mouths of Jinghai, Rushan, Dingziwan,Aoshan, and Xiaodao bays, it forms fans with greater thicknesses than those of the surrounding sediments.The maximum thickness is up to 22.5 m.

Grain size of the surface sediments was carried out in the Testing Center of Qingdao Institute of Marine Geology, using a Mastersizer-2000 laser particle analyzer (Malvern Company, UK) , after pretreating with 10% H 2 O 2 and 0.1 N HCl to remove organic matter and biogenic carbonate. They were defined according to the percentage composition of sand, silt and clay by the Shepard classification.

Unlike the eastern tip of the Shandong Peninsula where there are very few fluvial sediment deposits on the seafloor within 20 km of the shore (Yang and Liu,2007), the newly acquired high-resolution seismic profiles reveal two sediment depocenters off the southern Shandong Peninsula (Figs.2–4). The nearshore depocenter is approximately 12 km away from the coast and the off shore depocenter is approximately 30 km from the coast. Between the two depocenters is a linear depression (Fig.5). The deposits directly overlie a strong acoustic reflector,which has been explained as the last transgressive surface, and both deposits can be divided into lower and upper units by a maximum flooding surface.

The mud deposit can be classified into nearshore and off shore deposits by diff erent sedimentary architecture and both can be divided into upper and lower units by the Holocene maximum flooding surface (MFS). Between the two depocenters, a linear depression is seen. TS: transgressive surface.

We collected another borecore WHZK01 at a water depth of 15.80 m in this study area (Liu, 2016; Liu et al., 2016). The core site (36°26′N, 123°23′E) is located in muddy sediment on the seismic line(Fig.1b) and the average recovery of sediments is 91%.

In contrast to the nearshore deposit, the lower and upper units of the off shore deposit display two distinct acoustic features. The lower unit is characterized by aggradation with low-angle internal reflectors dipping gently seaward and truncated by the Holocene maximum flooding surface. It thickens toward the south and east, up to 12 m in the study area (Fig.2).The upper unit, which landward part of the omegashaped distal subaqueous deltaic lobe revealed by Yang and Liu (2007), exhibits aggradation and progradation landward rather than seaward, with internal reflectors dipping to the west and north at a steeper gradient. Locally deformed reflections can be seen. It thins toward land, with 23 m the greatest thickness in the east.

The isopach of the deposit in the study area is a little diff erent from that described by Yang and Liu(2007), especially the western margin (Fig.5). The mud deposit is not thin gradually landward. A linear depression exists between the two depocenters. Figure 5 shows that the deposit outside the Jinghai Bay ismuch thicker than those outside Rushan and Dingziwan bays, but the annual discharge of rivers that empty into Jinghai Bay (15×10 4 t/a) is much less than that of Rushan Bay ((30–50)×10 4 t/a) or Dingziwan Bay (84×10 4 t/a). This discrepancy may exist because Jinghai Bay is an open bay in which most river sediments directly empty to the sea,whereas the Rushan and Dingziwan bays are semienclosed and parts of the river discharges are trapped in the bays.

Fig.6 Spatial distribution maps of silt, clayey silt, and sandy silt surface sediment types in this study area

The gray lines indicate the newly acquired seismic profiles and the figures such as 6.2 mean the mean grain size (in Φ) of the surface sediments.

The surface sediment types in this area can be divided into silt, clayey silt, and sandy silt (Fig.6). At the mouth of Jinghai Bay, the sediments are mainly silt and become finer seaward, changing to clayey silt,but become coarser sandy silt at the western boundary of the off shore depocenter, indicating energetic physical conditions. Grain size is similar to that of core QDZ03. Core QDZ03 can also be divided into the upper and lower unit corresponding to the seismic profile (Fig.7). The upper unit of core QDZ03 is mainly composed of green-gray and yellow-greengray clayey silt that contain sporadic shell fragments.The lower part (4.80–7.70 m) has very uniform grain sizes, with mean values from 6.9 to 7.2 Φ (7.0 Φ on average), whereas the sediment above 4.80 m has a wider range in mean grain sizes from 5.8 to 7.2 Φ and a slightly coarser average as a whole (6.6 Φ on average), and the lower unit is mainly composed of green and yellow-gray clayey silt intercalated with lenticular beds and thin bands of silt or fine sand.These coarser-grained intercalated bands decrease upward gradually, showing a normal grading. The mean grain size is 6.0 Φ. Sporadic shell fragments and moderate bioturbation are present (Qiu et al.,2014). So the main body of the mud deposits is composed of fine sediments.

The Shandong Peninsula has an indented coastline with many bays (Fig.1b). The Qinglong River and other seasonal short streams contribute an annual sediment discharge of 15×10 4 t to Jinghai Bay. The Rushan and Juhe Rivers discharge (30–50)×10 4 t sediments into Rushan Bay annually. The Wulong River, which is about 124 km long, contributes average 84×10 4 t sediments to Dingziwan Bay (data from 1958–1980). Besides, seasonal short streams empty (2.31–3.90)×10 4 t sediments into Aoshan and Xiaodao bays annually. The Dagu River, which is the largest river on the Shandong Peninsula, empties into the Jiaozhou Bay. Its main channel can reach 180 km in length, and contributes an annual sediment discharge of 95.9×10 4 t to Jiaozhou Bay historically.However, its middle and lower reaches have run dry since the late 1970s except during flood seasons(Editorial Board of Annals of Bays in China, 1993).

5 DISCUSSION

Numerous studies have found a rapid deposition and accumulation center near many large river mouths worldwide, such as the Ganges-Brahmaputra (Kuehl et al., 1997) and Huanghe Rivers (Bornhold et al.,1986). However, smaller rivers also play important roles in the transfer of terrigenous sediment to the global ocean (Milliman and Syvitski, 1992) and can have profound impacts on both short-term and longterm characters of a coast (Syvitski and Saito, 2007)and seafloor (Milliman et al., 2007).

As with mud deposits elsewhere (Lee and Chu,2001; Weight et al., 2011), development of the mud deposits in this study area resulted from multiple factors such as sea-level changes, sediment sources,and sedimentary dynamic conditions. During the Last Glacial Maximum, sea level was 120 m below the present level and the Yellow Sea shelf was entirely subaerially exposed (Liu et al., 2004). With the postglacial sea-level rise, the shoreface moved landward across the shelf, forming the regional transgressive surface, which initially formed around 11 ka in the study area (Qiu et al., 2014). The mud deposits formed during the Holocene because they directly overlie the transgressive surface.

Depositional sequences and bounding surfaces(onlap, downlap, truncation, and toplap) were identified from reflector characteristics in the seismic data. An acoustic velocity of 1 550 m/s was used to calculate the sediment thickness based on previous drilling and seismic experience.

More than 300 km of high-resolution seismic profiles and 18 surface sediment samples were acquired off the southern Shandong Peninsula in October of 2013 (Fig.1b). The seismic profiles were acquired using SBP/AAE high-resolution profiler made by Applied Acoustic Engineering Company,UK. All seismic data were obtained with a pulse energy of 400 J fired at 800 ms intervals and a frequency band of 500–5 000 Hz. The seismic grid consists of 5 main profiles trending N-S and 2 connecting profiles trending W-E. The surface sediments were sampled with a grab.

The Huanghe River discharged mostly or entirely into the Bohai Sea in the past 7 ka, except during the 1128–1855 AD, when it shifted to the south (Saito et al, 2001). Extensive geological and geophysical surveys conducted in the Yellow Sea indicate that the upper unit of the off shore deposit is a continuous sediment body connecting to the along-shelf clinoform off the northern Shandong Peninsula (Liu et al., 2004;Yang and Liu, 2007), so there is no doubt that it is mainly Huanghe River-derived. The formation time,in the past 7 ka, is the same as the thick mud mound belonging to the highstand system tract at the eastern tip of the Shandong Peninsula (Yang and Liu, 2007).Based on the thickness of the mud distribution, using the Volume tools in Surfer 11, we calculate the total volume of the nearshore deposit is about 4.97× 10 10 m 3 or 6.0× 10 10 tons (assuming a dry density of 1.2 t/m 3)(Chen et al., 2003).

Assuming a relatively constant sediment discharge of 50 × 10 4 t/a for the Rushan River into Rushan Bay,84× 10 4 t/a for the Wulong River into Dingziwan Bay,and 3.9× 10 4 t/a for small rivers into Aoshan Bay and Xiaodao Bay (Editorial Board of Annals of Bays in China, 1993), approximately 1.5× 10 10 tons of sediment were emptied into the bays by the rivers during the development of the clinoform within the last 11.0 ka. This estimate of sediment discharges can be considered a maximum because present fluvial sediment loads are higher than those of ca. 2000 years BP because of human activities, as evidenced by the cases of the Yangtze River and Huanghe River (Saito et al., 2001). Moreover, the estimated sediment discharge (1.5× 10 10 tons) must have included sediments that were deposited in bays in addition to those transported out of the bays to the clinoform by tides, waves, and alongshore currents. The implication is that the total amount of sediment (about 6.0× 10 10 tons) in the clinoform must have come from other sources in addition to the local small rivers.These sources likely include the Huanghe River.Marine currents in the region transport sediments from the Huanghe River through the Bohai Strait and along the coast of the Shandong Peninsula to the study area (Fig.5).

The linear depression between the two depocenters may be because of local strong dynamics. It indicates a boundary for the subaqueous delta off the Shandong Peninsula. It may be related to the strong shear stresses (Pirmez et al., 1998) caused by strong tidal currents, similar to conditions at the eastern tip of the Shandong Peninsula (Yang and Liu, 2007). The area may also suff er erosion due to local complex current regimes. This agrees with the grain size distribution:sandy silt occurs in the depression, which is surrounded by finer sediment (silt or clayey silt).

6 CONCLUSION

Newly acquired high-resolution seismic profiles reveal two mud depocenters off the southern Shandong Peninsula in the Yellow Sea, which have diff erent sedimentary architectures and can be divided into upper and lower units by the Holocene maximum flooding surface. Between the two depocenters is a linear depression. The source of the nearshore deposit is the joint contribution from the local small rivers on the Shandong Peninsula and Huanghe River. The upper unit of the nearshore deposit belongs to the highstand system tract and the lower unit belongs to the transgressive system tract. The upper unit of the off shore deposit belongs to the highstand system tract and connects to the along-shelf clinoform off the northeastern Shandong Peninsula. The lower unit of the off shore deposit belongs to the transgressive system tract and is characterized by aggradation. The linear depression combines the two deposits and indicates the boundary of the subaqueous delta off the Shandong Peninsula.
