“…Thus, as shown in the Figure b, regional provenance source areas in the SCB are divided into two geographic areas, with Cretaceous igneous rock dominating the southeast coast and a combination of middle to late Jurassic magmatic rocks and ancient rocks to the west. These observations and differentiations were also noted in recent detrital zircon studies of Shao et al () and Deng et al ().…”

Paleogene syn‐rift successions in the South China Sea are poorly understood and systematic provenance analysis, which could provide clues to their history, is lacking. Here we report 409 new concordant U‐Pb ages from detrital zircons separated from the Paleogene Wenchang, Enping, and Zhuhai formations in the Zhu 1 depression, Pearl River Mouth Basin. The new data, combined with the published age data from the region, document changes in the provenance of syn‐rift successions. Detrital zircons from the Eocene Wenchang Formation are unimodal, with Jurassic‐Cretaceous (180–80 Ma) ages making up >80% of grains. The ages are consistent with the geochronology of intrabasinal highs, dominated by igneous rocks emplaced during the Yanshanian orogeny, and suggest local provenance. By contrast, detrital zircons from the upper Eocene to lower Oligocene Enping Formation form three well‐recognized age‐clusters, with peaks at 150, 254, and 438 Ma that match documented tectonomagmatism in South China Block (SCB). Combined with increasing numbers of Precambrian zircons, the data suggest increasing influence of regional provenance of the SCB. Similar age peaks are also recognized from the limited number of zircons analyzed from the upper Oligocene Zhuhai Formation and comparability with modern shelf and river sediment indicates the unit was mainly sourced from the SCB and likely transported by a paleo‐Pearl River. We infer that the change in provenance, from local uplifts within the Zhu 1 to the SCB, is related to distinct phases of PRMB rift development; however, later changes are best explained by SCB drainage evolution.

“…It is worth noting that there is a significant geochemical disparity between the whole sediments and clay of the western Taiwanese rivers (Figures 2 and 4). The geochemistry of the clay fraction is very similar to that of the Yangtze sediments from Sc/Th-Cr/Th and Zhejiang-Fujian riverine sediments from Ti/Zr, suggesting Taiwan's sedimentary metamorphic rocks originated partially from the regenerative continental crust of East China [23,64,65] (Figures 2 and 4).…”

“…The two elements are often concentrated in the mineral of zircon, which is widely distributed in felsic igneous rocks and sedimentary rocks due to its strong weathering resistance [57]. The East China mainland and Taiwan are dominated by felsic igneous rocks of the Mesozoic and low-grade sedimentary metamorphic rocks of the Himalayan, respectively, causing their riverine sediments to be rich in Zr and Th [64] ( Figures 1 and 2). It is worth noting that there is a significant geochemical disparity between the whole sediments and clay of the western Taiwanese rivers (Figures 2 and 4).…”

Sediment geochemistry is affected by sediment granularity and chemical partition, which may greatly influence the accuracy of sediment source identification. In this study, we analyzed Ca, Co, Zr, V, Cr, Ti, Sc, Th, and Al in the sediments of major rivers and a Holocene core along the eastern coast of China to reveal the constraints on sediment geochemistry related to granularity and chemical partition and to try and identify the sources of the sediments present in the core. The results reveal that the element concentrations have a significant positive correlation with Al concentration in all these riverine sediments. There are significant differences in the element contents of the bulk sample and the residual sediment leached with acid, including in their ratios. The ratios of Cr/Th-Sc/Th, which is often used for provenance discrimination, reveal that uncertainty of provenance discrimination will increase if the impact of sediment granularity and chemical phase on the index system is not considered. We applied this geochemical approach for provenance on a Holocene core of the East China Sea using Cr/Th-Al, Sc/Th-Al, Ti/Zr-Al, and Cr/Th-Sc/Th with the same granularity as the residue sediments. Based on this approach, we identified the core sediments to have had a large component derived from the western Taiwanese rivers since the mid-Holocene. This study sheds light on the sediment geochemistry used to identify the provenance of marginal seas with multiple rivers entering them. geochemical indicators to trace provenance often leads to uncertainties or an inaccurate identification of the source if the abovementioned factors are not fully considered [11][12][13].Many studies have used the geochemical analogy of modern riverine sediment to identify sediment sources of the cores along the eastern coast of China [7,[14][15][16][17][18][19][20][21][22]. The key to provenance discrimination is to set up an analogy of the geochemical fingerprints using potential riverine sediments. However, few studies cover sediment geochemistry of all the rivers involved due to the number of rivers entering the East China marginal seas. Many articles have compared the geochemical characteristics between some of these rivers, including large rivers such as the Huanghe and Yangtze as well as small mountainous rivers from the Zhejiang-Fujian coast and also Taiwan, where most rivers are large rivers [5,[23][24][25][26][27]. Of note, the granularity and chemical phase of sediments used for geochemistry are not uniform in these studies. Many studies have used the geochemical analogy of modern riverine sediment to identify sediment sources of the cores along the eastern coast of China [7,[14][15][16][17][18][19][20][21][22]. However, recent studies have revealed the heterogeneity of geochemical composition caused by grain size related to hydrodynamic sorting and chemical phases in the riverine sediments [12,23,[27][28][29][30][31]. Therefore, it is necessary to review the impact of sediment grain size and chemical phase on the geochemistry of...

“…This observation cannot be reconciled with the paleo-Min River model and it suggests, instead, that a drainage similar to the modern Yangtze River may have been established prior to the middle Miocene (Zhang et al, 2017).

“…Some workers cite changes in the rate and direction of subduction between the India and Eurasian plates and/or Pacific and Eurasian plates as the primary cause . Guo et al (2015) suggested that the subduction of Philippine Sea Plate beneath Asia caused the western margin of Okinawa Trough to be pushed westward and Deng et al (2017) and ages used in pie charts are from Zhang et al (2017). The yellow lines in the pie charts separate the Precambrian age populations from the Paleozoic-Mesozoic ones.…”

Researchers have long suspected a source‐to‐sink link between the Yangtze Block (and/or North China Block) and Eocene‐Miocene passive margin strata in Taiwan, and various models have been proposed to explain similarities in provenance and the presence of Archean grains. The East China Sea Shelf Basin, whose evolution has been neglected in most models, resides between potential mainland China source regions and the sediment sink in Taiwan, and occupies the corridor through which sediment would have been transported. Here we present 378 new concordant detrital zircon U–Pb ages from the Oligocene Huagang formation in the Xihu Sag, eastern East China Sea Shelf Basin. We also present a compilation of published detrital zircon data from major rivers across mainland China to evaluate potential sediment source regions. Detrital zircons in the Huagang formation range in age from 33 ± 0.4 to 2842 ± 43 Ma, with major clusters at 100–300 and 1,600–2,200 Ma and small early‐middle Paleozoic, Neoproterozoic, and Paleoproterozoic to Archean peaks. Visual and statistical comparison of age distributions suggest close relationships between the Min River and Eocene–Oligocene samples from western Taiwan and between the Oligocene Huagang formation and Miocene strata in western Taiwan. Combined with the tectonic and depositional evolution of the region, these observations suggest that Eocene–Oligocene sediments in Taiwan were mainly sourced from the Min River or similar drainage in the Cathaysia Block. However, the similarities between the Huagang formation and Miocene strata are best explained by reworking of the Oligocene sediment in the Xihu Sag and transportation to western Taiwain during Miocene tectonic inversion of the East China Sea Shelf Basin.
