Based on literature from the WOS and CNKI databases and using CiteSpace software, this study conducts a quantitative analysis of tourmaline research from 2000 to 2025 in China and abroad. Through publication volume statistics, keyword co-occurrence, and burst detection mapping, the study reveals the similarities, differences, and evolution of the research. The findings are as follows: (1) International research focuses on fundamental theory and technological innovation, emphasizing geochemical processes, fluid inclusions, and crystal structure analysis, creating an interdisciplinary framework, (2) Research in China is more application-oriented, focusing on mineral resource development, regional metallogenic models, and rare metal exploration, with significant achievements in pegmatite-type deposits and new energy minerals, (3) There are significant differences in technical approaches: international research relies on high-precision technologies (e.g., X-ray morphology and isotope analysis) to enhance theory, while China relies on traditional geological frameworks, with basic theories and technological innovation lagging behind. It is recommended to strengthen interdisciplinary integration and technological application, promoting collaboration between regional achievements and global metallogenic theories. Future research could explore the potential applications of tourmaline in environmental science and deep exploration, leveraging big data and AI technologies for intelligent exploration.
