Abstract:

The Jiaoxibei gold ore concentration area is characterized by abundant gold resources and diverse metallogenic types. In recent years, significant progress has been made in gold metallogenic theory and deep mineral exploration in this region, driven forward by the continued advancement of national strategic initiatives aimed at achieving breakthroughs in mineral exploration. Based on a comprehensive review of research achievements related to gold deposits in Jiaoxibei, this paper outlines the regional geological setting, analyzes the spatial distribution and metallogenic features of representative deposits, and establishes a regional metallogenic model. Particular attention is given to the genetic processes of gold mineralization, including a systematic summary of the formation mechanisms and differences among major deposit types, as well as a detailed discussion of the coupling interactions among tectonic activity, magmatic intrusion, and hydrothermal fluid migration. Additionally, this study reviews recent advances in gold exploration technologies and methodologies, emphasizing the integrated application of geophysical, geochemical, and remote sensing techniques. The emergence of data-driven prospecting methods is also discussed. Nevertheless, several challenges remain in current exploration practices, including insufficient integration of multi-source data, reliance on traditional geological survey-based models, and the early-stage development of intelligent prospecting technologies. Finally, the paper proposes key future research directions for data-driven mineral exploration in the Jiaoxibei region, aiming to enhance exploration efficiency and promote methodological innovation.
