“…Cameselle et al (2017Cameselle et al ( , 2020 suggested that the spreading center propagated westwards and died shortly before reaching the Xisha Trough in the late Early Oligocene, an interpretation that is not compatible with the observations reported in the present study.

A 3D Snapshot of Crustal Breakup Deduced From Seismic Analysis of the Tip of the NW South China Sea

Based on a high‐resolution seismic reflection data set, we describe and map rift domains at the tip of the V‐shaped NW‐South China Sea (NW‐SCS) Basin. We compare our rift domain map with seismic refraction, magnetic and gravity field data, and previously mapped Continent‐Ocean Boundaries (COB). We also define and map syn‐breakup sedimentary and magmatic sequences across the sediment‐rich NW‐SCS, which enables us to reconstruct the tectono‐stratigraphic evolution of the area. This work enables us to describe and discuss the 3D architecture and nature of the crust at the tip of the NW‐SCS, investigate how extensional and magmatic processes interacted during the breakup, and propose a kinematic model for late rifting, breakup, and finally stalling of the seafloor spreading system. This study provides exceptionally well‐documented insights into the spatial and temporal evolution at the tip of a so‐called “rift propagator,” and enables us to show that breakup in the NW‐SCS may rather correspond to a “retrogrador,” in which the extension zone retreats due to the reorganization of a failing rift system.

Seismic Imaging of an Intracrustal Deformation in the Northwestern Margin of the South China Sea: The Role of a Ductile Layer in the Crust

Rifting and lithosphere thinning eventually lead to continental breakup and oceanic spreading. As many continental margins show similar behavior in rifting, simple models were proposed to explain the crustal extension. For example, the "pure-shear" extension model was established to describe symmetric and uniform rifting (McKenzie, 1978), while the "simple-shear" model takes asymmetry further into account (Wernicke, 1981). Today, additional geophysical data challenge the abovementioned models and indicate a depth-dependent extension which favors strong decoupling between intracrustal layers (Hopper
