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
