Abstract: The gravity and magnetic exploration play a significant role in polymetallic deposit exploration due to their high sensitivity responses to density and magnetic anomalies, along with advantages of low-cost and high-efficiency. This paper systematically reviews recent advancements and key technologies in gravity and magnetic exploration methods, focusing on trending research areas such as target information extraction, novel inversion methods, and artificial intelligence applications. By summarizing and analyzing typical domestic and international application cases, the study outlines the development trends and prospect future research directions of gravity and magnetic exploration methods. This study provides a technical reference for mineral exploration practices while offering technological support for deep exploration of strategic metal deposits and national resource security assurance.
