TRANSCRIPT
- Dynamic topography output is interpolated to plate reference frame.
- Initial shape of the continent defined using total sediment isopach, Present day topography and predicted dynamic topography
- Differential dynamic topography is adjusted for sea-level change
- Predictions of coastline position, isopach thickness and tectonic subsidence by filling basins below sea-level
- Misfit calculations between observed and predicted isopachs, coastlines and tectonic subsidence.

Scripts for a Stratigraphic WorkflowModeling Low Velocity Structures in the Mantle with the Thermo-Chemical aspects of CitcomS
- Open-source application developed by Caltech, University of Sydney, and the Norwegian Geologic Survey (NGU)-Tectonic Feature Data is used to create global plate polygons- Plate polygon boundaries are computed upon each reconstruction- Global velocity data generated for geodynamic model, CitComS.
Semi-Automated processing of model input and output with suite of Python scripts and GMT calls.
- Global 3D Citcoms output is sliced along annular rings using code incorporated from CIG.
- Image generation scripts allow for detailed analysis of thermal structures
- Detailed modeling of slab physics
- Subduction Zone feature data is processed via GPlates in a GIS-like fashion
- Python scripts combine data from GPlates and slab parameters to build initial conditions for the convection model.
Image production options include:
- Single, double, quartet or six-panel figures- Map view, cross sections, annular rings
- Feature data overlay- Velocity data overlay
- Automatic Iteration over model level- Automatic Iteration over model age
