摘　　要：富铀矿物U-Pb体系微区原位定年技术在地球系统科学和自然资源综合地质调查中具有广泛的应用。为全面梳理其研究进展,探讨研究热点和发展趋势,本文利用CiteSpace对Web of Science核心数据库(WOS)和维普数据库(VIP)中1991—2024年期间共20469篇相关文献进行可视化分析,得到了相关知识图谱。结果表明,U-Pb微区原位定年分析领域的发展可大致分为3个阶段:起步阶段(1991—2001年)、快速发展阶段(2002—2018年)、稳定发展阶段(2019年—),主要取决于测试仪器、定年矿物拓展和数据处理软件三方面的进步。基于上述图谱分析,对U-Pb微区原位定年分析方法及其应用研究进展进行了总结,指出该领域前沿热点为不同矿物U-Pb定年的方法研发与应用拓展,下一步研究方向主要有以下几点:(1)应用飞秒激光和缩小一次离子束等技术以提高测试仪器的灵敏度、分析精度和空间分辨率;(2)研发高效的U-Pb预扫描技术并深入研究U和Pb在矿物中的赋存状态,完善低U矿物的微区原位分析方法;(3)研制不同组成不同年龄的标准物质,或建立非基体匹配方法,解决某些定年矿物标准样品稀缺的问题;(4)建立新矿物的U-Pb微区原位分析方法,尤其是沉积岩和矿床中的矿物,进一步拓展其应用领域;(5)研发基于AI的智能数据处理软件,避免数据处理过程中的主观影响。The in-situ U-Pb dating of uranium-rich minerals has extensive applications in geoscience and integrated geological surveys of natural resources.To comprehensively review its research progress and explore the research hotspots and development trends,this study utilized CiteSpace to conduct a visualization analysis of 20,469 related articles from the Web of Science Core Collection(WOS)and the VIP Database from 1991 to 2024,generating relevant knowledge graphs.The results indicate that the development of in-situ U-Pb dating can be broadly divided into three stages:the initial stage(1991—2001),the rapid development stage(2002—2018),and the stable development stage(2019—present).This progress has primarily been driven by advancements in three key areas:analytical instruments,the expansion of dating minerals,and data processing software.Based on the above visualization analysis,this paper summarizes the research progress in in-situ U-Pb dating methods and their applications.It highlights that the current research frontier focuses on the method development and application expansion of U-Pb dating utilization for various minerals.The future research directions include the following:(1)Applying femtosecond laser and reducing the primary ion beam size to enhance the sensitivity,accuracy and spatial resolution of instruments;(2)Developing efficient U-Pb pre-scanning techniques and further investigating the occurrence states of U and Pb in minerals to improve insitu dating methods of low U minerals;(3)Developing reference materials with diverse compositions and ages,or establishing non-matrix-matched methods to address the scarcity of reference materials for certain dating minerals;(4)Establishing in-situ U-Pb dating methods for new minerals,especially those in sedimentary rocks and ore deposits,and expanding their application fields further;(5)Building AI-based intelligent data processing software to eliminate subjective influences in data processing.
