ASPECT-Based 3D Mantle Convection Models and Stress Inversion Data for the Korean Peninsula

Dataset Title: ASPECT-Based 3D Mantle Convection Models and Stress Inversion Data for the Korean Peninsula Description: This dataset contains the full model setup and observational data used for a suite of three-dimensional instantaneous mantle convection simulations conducted with the ASPECT geodynamic modeling code. The simulations investigate how subduction geometry and mantle thermal/compositional heterogeneity influence crustal stress beneath the Korean Peninsula and surrounding regions. The repository includes the following:Model setup files (.prm): ASPECT parameter files defining boundary conditions, plate configurations, and slab geometries.Initial condition fields (.txt):Temperature fields based on the FWEA18 S-wave tomography model, converted to physical temperature via Q-corrected thermodynamic inversion using BurnMan.Compositional fields based on Slab2.0 geometry, distinguishing slab and background mantle domains.Stress inversion data:stress_inversion/dir_SH_max_azimuth.dat – Observed azimuths of the maximum horizontal compressive stress (SHmax) derived from moment tensor solutions. This dataset is used to compare predicted principal stress orientations from the geodynamic models with seismic observations.Documentation: Text files and README describing domain setup (110–145°E, 20–50°N, 0–650 km), numerical resolution (0.125° × 0.125°, 25 km), rheology, and thermal structure. Output data: Each modeled velocity, strain rate, stress, and temperature within the upper mantle and lithosphere. Updated data: Moment Tensor and corrected composition fields
