GeoDecider: A Coarse-to-Fine Agentic Workflow for Explainable Lithology Classification

ArXi:2605.03383v1 Announce Type: new Lithology classification aims to infer subsurface rock types from well-logging signals, ing downstream applications like reservoir characterization. Despite substantial progress, most existing methods still treat lithology classification as a single-pass classification task. In contrast, practical experts incorporate geological principles, external knowledge, and tool-use capabilities to perform accurate classification.
