The South China Block (SCB) has been regarded by many as an integral part of Gondwana, but proposed timing and processes for its accretion to Gondwana vary and remain contentious, largely owing to the lack of reliable Pan-African age paleomagnetic data and tectono-magmatic records from the SCB. Integrated in situ U-Pb ages and Hf-O isotope analyses of detrital zircons from geochronologically well-calibrated Ediacaran-Cambrian sedimentary rocks of western SCB reveal age populations of 2.51, 1.85, 1.20, 0.80, and 0.52 Ga. Detrital zircon age spectra indicate a major tectonic transition for the SCB during 0.56-0.54 Ga, interpreted to reflect the beginning of the collision between SCB-Indochina and NW India blocks. The collisional event lasted until early Ordovician, leading to the suturing of the SCB-Indochina to the northern margin of East Gondwana. Plain Language Summary The South China Block is thought to be a part of the Gondwana superterrane, which was composed of more than half of all continents 650-400 million years ago (Ma). However, questions of when and how the South China Block collided with Gondwana are yet to be answered. In this study, we conducted provenance analyses of sedimentary rocks whose depositional ages were known via radioisotopic dating and chemo-biostratigraphy in the western South China Block. The results reveal a change in tectonic setting of the South China Block at 560-540 Ma, interpreted as the onset of the collision between the South China Block and India along the northern margin of East Gondwana.

“…A possible interpretation is that the sediments might be influenced by the local source from central Vietnam and mixed with the detritus from Red River. The Neoproterozoic zircon grains in the sample were probably eroded from the Paleozoic sedimentary rocks near to the coast of central Vietnam (Wang et al, 2016a).…”

“…Recently, Burton‐Johnson et al (2020) reported Triassic zircons from Triassic granitoids in eastern Sabah, which could also have provided a minor contribution. The Precambrian zircons are multi‐cycled and show similarities with sediments in Sibumasu (Liebermann et al, 2017; Sevastjanova et al, 2011), East Malaya (Dodd et al, 2019; Sevastjanova et al, 2011), Indochina (Burrett et al, 2014; Carter & Moss, 1999; Hennig et al, 2018; Nguyen et al, 2018; Wang et al, 2016), West Borneo (Breitfeld et al, 2017) and basement rocks in South China (Chen et al, 2016; Li, 1997; Liu et al, 2009, 2014). These zircons are probably recycled in the tidal embayment of the SCS from older clastic successions in Borneo that were exposed along the northern margins of Sarawak and Sabah.…”

A 2 m thick bed of smectite‐rich clay within a sequence of distal deep water turbidites and marine mudstones of the Temburong Formation on the island of Labuan, Sabah, North‐West Borneo, is an altered, re‐sedimented pyroclastic tuff which is geochemically of rhyolite‐dacite composition. The tuff bed was deposited in deep water, although probably <1,000 m, by traction currents and retains relic siliceous shards, feldspar phenocrysts and biotite crystals but was dominated by ash‐grade material. The tuff is interpreted as a turbidite deposit and most probably records long distance sub‐marine transport down the depositional slope from an active volcanic system in the hinterland. It has a zircon U–Pb weighted mean age of 19.6 ± 0.1 Ma whilst combined forminiferal and nannofossil ages from the enclosing marine mudstones range from 21.5 to 19.4 Ma; together these indicate an early Miocene age for the Temburong Formation. The tuff is the result of a very short‐lived volcanic arc magmatic episode and was either related to similar aged volcanics of the Sintang Suite in central Borneo or a product of the Proto‐South China Sea subduction beneath the Cagayan arc north‐east of Borneo. The age indicates that deep water sedimentation in North‐West Borneo continued into the Burdigalian suggesting the subduction trench of the Proto‐South China Sea was active into the early Miocene, beneath the depocentre of the Temburong turbidite fan. By contrast, sandstones representative of the typical marine Temburong Formation yield abundant zircons which are dominately Cretaceous in age indicating an important switch in source provenance during the Early Miocene from the Crocker Formation that is dominated by Permian‐Triassic zircons. This difference in zircon populations likely reflects an important tectonic event in the early Miocene that resulted in uplift of central Borneo to supply sediment to the Sabah Trough whilst the input of material derived from the western terrains diminished. The Temburong Formation was sourced by reworking of uplifted Rajang Group, Sapulut or Trusmadi formations.
