Joint 3D Gravity and Magnetic Inversion via Rectified Flow and Ginzburg-Landau Guidance

arXiv:2603.06829v2 Announce Type: replace Abstract: Subsurface ore detection is of paramount importance given the rising depletion of shallow mineral resources in recent years. It is crucial to explore approaches that go beyond the limitations of traditional geological exploration methods. Due to readily available surface readings, joint magnetic and gravitational inversion is a promising new method - given magnetic and gravitational data on a surface, jointly reconstructing the underlying densities that generate them. However, this is ill-posed and has non-unique solutions. Deterministic meth

Why this matters
Why now

The increasing depletion of shallow mineral resources is driving the urgent need for advanced subsurface exploration methods, making AI-driven solutions for geophysical inversion highly relevant at this moment.

Why it’s important

Advanced AI techniques for geophysical inversion can significantly improve the accuracy and efficiency of discovering critical mineral resources, impacting global supply chains and resource security.

What changes

The ability to more reliably reconstruct subsurface densities using AI will improve the precision and success rates of ore detection, potentially lowering exploration costs and opening new mining prospects.
