Short summary
This study makes use of advanced seismic exploration techniques to look at the subsurface of South Africa's Kheis region. The results reveal hidden faults and folded rocks that help explain how ancient continents collided. The findings challenge older ideas about major geological boundaries and suggest a new model for how the crust formed and evolved. This work shows how old data, when re-analyzed with new methods and integrated with supporting data, can disclose important geological qualities.
