New RL method trains AI to reason about geological event histories

Researchers have developed Geo-Strat-RL, a synthetic environment designed to train vision-language models (VLMs) in reasoning about geological event histories. This system uses reinforcement learning with verifiable rewards (RLVR) to generate stratigraphic observations and associated event histories, which are then scored by an executable verifier for accuracy in chronology, event identity, deposition, and structural relationships. The study demonstrates that RLVR training improves VLMs' geological reconstruction capabilities, with reasoning learned from stratigraphic diagrams showing transferability to synthetic seismic representations without requiring seismic-specific training.
