Abstract The density structure of the cratonic lithospheric mantle (CLM) remains debated. We suggest that one important reason for which many geodynamic studies favor neutrally buoyant CLM is they adopted separate reference frames when estimating isostatic effects continental and oceanic lithosphere, while instead a globally consistent should be used. This reflects misconception crust perfectly balances surrounding lithosphere. Using unified global frame with recent constraints on crustal...
Plate subduction drives both the internal convection and surface geology of solid Earth. Despite rapid increase computational power, it remains challenging for geodynamic models to reproduce history Earth-like associated mantle flow. Here, based on an adaptive approach sequential data assimilation, we present a high-resolution global model since mid-Mesozoic. This incorporates thermal structure kinematics tectonic plates recent plate reconstruction observed configuration convection....
Abstract Geoid is a key observable for understanding the dynamics of deep Earth, but has been considered largely transparent to long‐wavelength shallow density structures, especially those cratonic lithosphere. Here, we demonstrate that observed flat craton‐ocean geoid pattern, traditionally interpreted as reflecting neutrally buoyant keels, provides critical constraints on both net buoyancy and depth‐dependent distribution mantle Using simple theoretical calculations quantitative numerical...
Abstract Uncertainties in the origin and composition of oceanic asthenosphere lead to different views on its temporal evolution upon subduction. We investigate material during subduction using high‐resolution geodynamic models. In contrast some earlier models suggesting that limited amount can be entrained subduction, we find much subslab mantle (>100 km thick) could recycle into deep following slab, even if this layer remains buoyant less viscous entrainment. Our results support...
Abstract Quantifying past mantle dynamic processes represents a major challenge in understanding the temporal evolution of solid earth. Mantle convection modeling with data assimilation is one most powerful tools to investigate dynamics plate subduction and convection. Although various methods, both forward inverse, have been created, these methods all limitations their capabilities represent real Pure models tend miss important structures due incorrect initial condition thus may lead...
