Geodynamics of a global plate reorganisation from topological data analysis (Supplementary material)

This repository contains supplementary data associated with Janin et al. (2025, Nature Geoscience).

Specifically, it includes the complete plate graph representing the evolution of the plate network over 474 million years at the surface of the mantle convection model presented in Coltice et al. (2019, Science Advances).

The dataset includes:

• A raw DOT file encoding the full plate graph
• A corresponding JPG image generated from the DOT file using the open-source visualization tool Graphviz.

These files provide a visual and structural representation of plate interactions through time in the simulation.

The graph is represented following the same graphical conventions as in Fig. 3 of Janin et al., (2025, Nature Geoscience), except for the colours of plates: plates are coloured according to their velocity in a NNR reference frame (in mm.yr−1 ). The size of vertices is a function of the plate area. Seven present-day Earth plates are given as reference (PA, Pacific; NU, Nubia; AU, Australia; NZ, Nazca; AR, Arabia; CO, Cocos; JF, Juan de Fuca). We make the distinction between plates having more than 1/3 of their total area formed by continental lithosphere (represented by pentagons) and the others (represented by circles). Time moves forward from top to bottom. Horizontally, plate positions are arranged to minimize the overlaps between plate trajectories over the entire 474 Myr period.
