“…The Xuefeng Shan domain that mainly exposed the Precambrian crystalline basements has been superposed by Caledonian and Indosinian intracontinental orogens in the Phanerozoic [6,18]. During the Caledonian intracontinental orogeny, syndepositional faults and folds dipping to NW or SE were developed in the eastern Xuefeng Shan domain [44]. Synchronous massive granite emplacement and metamorphism between 467 Ma and 400 Ma with peak age ~440 Ma in the Xuefeng Shan domain to the east of the Anhua-Luocheng fault probably originated in Proterozoic metapelite and metaigneous rocks [6].…”

“…Synchronous massive granite emplacement and metamorphism between 467 Ma and 400 Ma with peak age ~440 Ma in the Xuefeng Shan domain to the east of the Anhua-Luocheng fault probably originated in Proterozoic metapelite and metaigneous rocks [6]. Both the deformation and massive granites indicate the crust of the Xuefeng Shan has thickened and continuously uplifted since early Ordovician time [6,44].…”

“…This indicates that the Xuefeng Shan domain may have uplifted and unroofed as early as Middle Ordovician time (Figure 10). With continuous uplift of the Xuefeng Shan domain, the depositional depocenter of the centralupper Yangtze Block transited from the western front of the Xuefeng Shan to the southcentral-upper Yangtze Block [24,43,44].…”

“…Lithofacies associations across South China continuously propagated westward from the slope facies with abundant of the terrestrial clasts supplied from the Cathaysia paleohighlands in the eastern margin of the eastern Yangtze Block [56] into the basin environment with shallow water structures [8,44] in the middle part of the eastern Yangtze Block (Figure 9(a)). To the west, slope facies (our study area) occurred again in the eastern limb of the Xuefeng Shan domain and gradually passed into the platform facies with detrital clasts mainly from western paleouplifts in the central-upper Yangtze Block (Figure 6).…”

“…The geochemical data indicated these intrusions mainly originated from the thickened Paleoproterozoic basement [6,8] indicating a Xuefeng Shan domain crustal thickening and topographic uplifting to become the backbulge of the retroarc foreland basin system. Thus, the Xuefeng Shan domain not only prevented the detritus of the Tethyan Himalaya from being transported into the eastern Yangtze Block, e.g., quartz clasts and detrital zircons in the Cambrian from the northern India [61] but also provided detrital clasts into both sides of the depressions, e.g., ~460 Ma zircon grains in both western and eastern Yangtze Block [23,44].…”

Amalgamation of the Yangtze and Cathaysia blocks in the context of Gondwana assembly in the early Paleozoic has been addressed for decades, but the far-field effects on the Yangtze Block during the amalgamation remain unclear. In this study, we outline the sequence stratigraphic framework of the Ordovician succession in the central-upper Yangtze Block and analyze provenance records in sandstone compositions, distributions, and detritus zircon U-Pb dating. The Ordovician succession in the central-upper Yangtze Block is subdivided into six third-order sequences, which were deposited mainly in a carbonate platform with restricted sediments in Tremadocian to early Floian stages, mixed terrigenous-carbonate deposits in mid- to late Floian stages, and open circulation sediments in Dapingian to middle Katian stages. These sequences show the central-upper Yangtze Block experienced syn-tectonic deformation with northeast-trending long-wavelength uplift and depression alternatively and the depocenter shifting from the east during Tremadocian to mid-Floian stages to the southwest in late Floian to early Hirnantian stages. Provenance data indicate that detritus in the Ordovician succession was mainly from the northern India and Kangdian paleohighland to the southwest of South China Block. Incorporating the depositional and deformation variations, we propose a retroarc foreland basin that was developed on the South China Block in response to final suturing between the South China Block and East Gondwana at Sanya suture zone. The South China Block was thus involved in the global tectonics of the Gondwana supercontinental cycle during the Ordovician.

Although continental shelves account for only approximately 7.5% of the ocean's surface, they are a globally important reservoir for terrigenous sediments (Saito et al., 1998). Therefore, sedimentary records from continental shelves are ideal for high-resolution studies on geological and environmental evolutions such as local tectonic subsidence, source-sink processes, and climate changes (e.g., Knies et al., 2003). In addition, as a transitional zone between the land and deep ocean, sedimentary architectures on the continental shelf, especially in low-gradient and broad continental margins, are controlled by a range of factors including variations in sea-level
