Abstract
En 中文
• First application of AlphaEarth Foundations semantic embeddings to mineral prospectivity mapping. • Pretrained AEF features represent mineralization-related spatial patterns without manual feature design. • The AEF-Transformer captures long-range spatial dependencies in copper mineralization systems. • A Confidence Index and majority-voting strategy improve uncertainty-aware exploration target delineation.
