“…The reconstructed crustal thickness of the South China margin (Figure 6) gradually increased from 33.7 ± 4.3 km to 41.8 ± 5.2 km during 270-215 Ma. After 160 Ma, the crust thickened significantly, up to 52.8 ± 6.4 km at 150 Ma, followed by another thickening event up The two periods of crustal thickening during 160-150 Ma and 120-90 Ma are compatible with Late Jurassic syn-orogenic shortening and the mid-Cretaceous collision of the Philippine Block with the Asian continental margin (Cao et al, 2020;Chu et al, 2019;Li et al, 2014. Following crustal shortening, significant extensional episodes in the Cretaceous overprinted the older shortening structures (Dong et al, 2020;Li et al, 2018) and led to the formation of the 'Southeastern China Basin and Range Province' (Gilder et al, 1991).…”

“…Recent works have provided highly insightful, yet variable, deformable plate models for a variety of tectonic settings (e.g. Cao et al 2020). However, this is not an entirely new approach and Dunbar and Sawyer (1987) were among the first to attempt a quantitative approach to deriving non-rigid plate reconstructions, followed by others (Srivastava & Verhoef, 1992; Williams et al 2011).…”

“…A recent advancement has been the inclusion of this approach in open source software such as GPlates (Gurnis et al 2018; Müller et al 2018), resulting in deformable plate models of many regions (e.g. Cao et al 2020) as well as globally (Müller et al 2019). In addition, other groups have also developed their own deformable modelling workflows (Smith et al 2007; Kneller et al 2012, 2013; Ady & Whittaker, 2019).…”

“…Gurnis et al (2019) used the GPlates deformable plate modelling methodology to study the Puysegur Trench, New Zealand, and similarly Liu et al (2021) used the GPlates deformable model workflow to study the subduction of the Pacific plate in East Asia. Recently, Cao et al (2020) applied this modelling workflow to the South China Block. The intraplate deformation in South China is closely related to the subduction of the Izanagi and Pacific plates.…”

“…The intraplate deformation in South China is closely related to the subduction of the Izanagi and Pacific plates. Thus, Cao et al (2020) demonstrate the applicability at settings that include a compressional phase. Zhu et al (2021) built a deformable plate model using GPlates of the Bohai Bay Basin in North China which is claimed to have implications for the entire East Asia region, demonstrating how insightful such reconstructions can be.…”

The recent proliferation of deformable plate tectonic modelling techniques has provided a new direction in the study of plate tectonics with substantial implications for our understanding of plate deformation and past kinematics. Such models account for intraplate deformation, yet are highly variable in their inputs, capabilities and applications. The aim of this commentary is to review recent contributions to this topic, and to consider future directions and major omissions. Through this review it is apparent that the current published deformable models can be subdivided into those that as an input either: (1) solely use plate motions to drive deformation, or (2) require stretching or beta factor. Deformable models are resolving some outstanding issues with plate reconstructions, but major simplifications and modelling assumptions remain. Primarily, obtaining model constraints on the spatio-temporal evolution of deformation is an outstanding problem. Deformable plate models likely work best when the kinematics of smaller plates are included. However, questions remain regarding how to define such blocks, and their kinematic histories, whilst some work suggests that inclusion of such entities is negated through quantitative restorations.

Plate tectonics, as the unifying theory in Earth sciences, controls the functioning of important planetary processes on geological timescales. Here, we present an open‐source workflow that interrogates community digital plate tectonic reconstructions, primarily in the context of the planetary deep carbon cycle. We present an updated plate tectonic reconstruction covering the last 400 million years of Earth evolution and explore components of the plate–mantle system that is involved in the exchange and storage of carbon. First, the workflow enables us to estimate subduction zone lengths through time, which represent the “tap” of carbon that is released at convergent tectonic margins. Second, we explore the role of Andean‐style versus intra‐oceanic subduction regimes during Pangea assembly and breakup. Third, we provide an improved model for carbonate platform evolution since the Devonian and evaluate the interaction of subduction zones and buried carbonate platforms. Last, we present a new model for estimating oceanic age, carbon content in the upper oceanic crust, and estimated (carbon‐containing) sediment thicknesses through time and present methods to track the subduction of this material through time. These components of the deep carbon cycle are key mechanisms controlling, or at least modulating, atmospheric CO2 on geological timescales and hence strongly influencing long‐term climate. We find that the mid to Late Cretaceous greenhouse climates were likely driven by increased subduction fluxes of volatiles and increased subduction zone interactions with carbonate platforms in the Tethyan tectonic domain. Our work highlights the importance of community digital plate tectonic reconstructions as a framework for studying key systems, such as the deep carbon cycle, that influence the life‐support mechanisms on our planet.
