Slab Rollback Versus Delamination: Contrasting Fates of Flat‐Slab Subduction and Implications for South China Evolution in the Mesozoic

Growing evidence supports that the widely developed Mesozoic folds and magmatism in the South China Block are attributed to the flat-slab subduction, followed by slab steepening, of the Paleo-Pacific Plate (PPP). However, the dynamics of the transition from flatto steep-slab subduction, as well as the relationship between tectonic processes and surface deformation and magmatic events, are poorly constrained. Using a 2-D thermomechanical numerical model, we systematically investigate the effects of slab rollback or delamination following the eclogitization of a subducted oceanic plateau on the surficial topography, structural deformation, and magmatism. Our results indicate that the subduction of an oceanic plateau drives flat-slab subduction, which further leads to the development of a wide thrust fault zone, an uplifted and magmatically active foreland, and the foreland basin subsidence. This model is further complicated by the transition from flatto steep-slab subduction through slab rollback or delamination which is controlled by the subduction rate and the timing of oceanic plateau eclogitization. The comparisons between our numerical results and the geological data from South China reveal that the slab delamination model reproduces the regional evolution of the Mesozoic South China. Based on our models, we suggest that the eclogitization during flat-slab subduction is not instantaneous, which is instead at least 18 Myr after the oceanic plateau reaches the ideal conditions of phase change.

There has been no consensus yet regarding the precise initial timing and duration of the late Mesozoic extensional tectonics in the South‐eastern China Block. This work focusses on the growth strata of the Early Cretaceous red beds in the South‐eastern China Block to determine the late Mesozoic tectonics and the precise timing of the initiation and duration of extensional tectonics in this area. Field observation of several terrigenous basins shows that the dip angles of the Cretaceous red beds have varied from moderate to gentle from basin edges to interiors (or centres). The visible and estimated thickness within a single bed increases slightly downwards from the upper to the lower part. These characteristics indicate that the sedimentary area of these beds has undergone an extensional process with expansion and deepening of the sedimentary basins. Rotation of the border surfaces (limbs) and downward warping of the hanging walls or retreat of the footwalls of listric normal faults causes three types of extensional growth (or syntectonic) strata in the deposits of different basins. Dating of the volcanic rocks related to the growth beds reveals that the sedimentary basins were enlarged and deepened when the Early Cretaceous strata were deposited in the South‐eastern China Block from ca 140 to 137 Ma. Regionally, under the influence of Palaeo‐Pacific plate rollback since ca 140 Ma, the South‐eastern China Block stress field has led to lithospheric uplift and pull‐apart structures near the surface, causing the half‐graben basins to receive sedimentation. Although the extensional event was interrupted by a short compressional event during 120 to 105 Ma, with the oceanward retreat of the trench, the area of extension gradually enlarged and rejuvenated south‐eastwards until the end of the Cretaceous. This Cretaceous extension event of the South‐eastern China Block must belong to a worldwide geological event with global significance.

Cenozoic tectonic evolution of South China: A brief review, and new insights from the Huangshadong‐Shiba area, south‐east China

The Cenozoic tectonic dynamic process controlled by the Pacific subduction and Tethyan subduction/collision in South China are still controversial and lacks geological evidence of intracontinental deformation to define. Here, we focused on the Huangshadong-Shiba area (HSA) in the southeastern coastal area of China. This study aims to obtain multi-stage geological events by an integrated multidisciplinary investigation to decipher the multiple tectonic deformation in Cenozoic South China. We found that the Jurassic and Cretaceous granite not only dominates in surface magmatic rocks but also integrates into a whole with buried depth more than 2 km. This plate-like granite (it means the occurrence of granite is like a tremendous plate) with thickness more than 3 km is sliced by Heyuan Fault, Renzishi Fault, and Zijin-Boluo Fault. The basalts in the Shiba Basin have an Ocean Island Basalt-like property, and the Heyuan Fault controlled the distribution of basalt. Our results, merged with a review of the Cenozoic tectonic evolution in South China, emphasise the decisive role of the India-Eurasia collision on the tectonics of South China in the Palaeogene and suggest the continuous northward drift of the Philippine Sea Plate and Australian Plate had a substantial effect on South China in the Neogene. This study also proposes a two-stage tectonic activity model to visualise the Cenozoic tectonic activity acting on the HSA or South China.
