Abstract: Copper is a strategic mineral resource with high external dependence in China, and its stable supply is crucial for national resource security. Porphyry copper deposits, as one of the most important sources of global copper resources, exhibit significant metallogenic potential and exploration value in Xinjiang, China. This study conducts a bibliometric and knowledge mapping analysis of research literature on Xinjiang porphyry copper deposits from 2000 to 2025 in the Web of Science (WoS) database using CiteSpace and GIS software. It systematically reviews the research progress, collaboration networks, hot topics, and development trends in this field from an international perspective. The results show that China dominates the research in this area, accounting for 76.3 % of the total publications, and has formed a close-knit institutional collaboration network centered on the Chinese Academy of Sciences. At the international level, the research team represented by Shen Ping constitutes a key academic network. Keyword co-occurrence and clustering analysis identified 10 main research directions, among which "West Junggar," "East Tianshan," "geochemistry," and "fluid inclusions" have long been research focuses, while "tectonic evolution," "multi-source big data," and "thermal history modeling" have emerged as recent frontiers. Through visualization, this study reveals the evolution of research on Xinjiang porphyry copper deposits, from early regional geological background exploration to the current focus on microscopic metallogenic mechanisms and intelligent prediction methods integrating multi-source data. The findings provide theoretical and literature support for deep exploration, target optimization, and technical integration in Xinjiang porphyry copper deposits, contributing to the systematization and intelligence of prospecting prediction.
