Reproducing past subduction and mantle flow using high-resolution global convection models

Plate subduction drives both the internal convection and the surface geology of the solid Earth. Despite the rapid increase of computational power, it remains challenging for geodynamic models to reproduce the history of Earth-like subduction and associated mantle flow. Here, based on an adaptive approach of sequential data assimilation, we present a high-resolution global model since the mid-Meso…
