About gtrack

gtrack (GPlates-based Tracking) is a Python package for computing lithospheric structure through geological time using plate tectonic reconstructions.

Key Features

• Seafloor Age Tracking: Compute oceanic lithosphere ages using Lagrangian particle tracking
• Continental Point Rotation: Rotate user-provided points through geological time
• GPlately Compatible: Results match GPlately's SeafloorGrid output
• gadopt Integration: Cartesian XYZ coordinates directly compatible with gadopt's interpolation

Use Cases

gtrack is designed for geodynamic simulations where you need lithospheric structure at past geological ages:

1. Oceanic lithosphere: Ages computed via seafloor tracking translate to lithospheric depth via thermal models (e.g., half-space cooling)

2. Continental lithosphere: Present-day structure from seismic tomography can be rotated back in time to reconstruct past configurations

Dependencies

gtrack uses pygplates as the underlying engine for plate reconstructions, with stripy for icosahedral mesh generation.
