摘　　要：地质年代研究是分析地质事件的基础,Re-Os同位素定年技术是地质学领域最重要定年技术之一。本文旨在找到科学的方法对近年来Re-Os同位素定年研究成果进行分析总结,梳理研究脉络和热点,为地质年代研究工作部署提供参考。研究方法是以近30年(1994~2023)与研究主题相关度较高的581篇文献资料作为研究对象,采用科学知识图谱分析技术,绘制研究作者合作图谱、研究机构合作图谱、研究关键词共现网络图谱、研究主题演进图谱等知识图谱,对Re-Os同位素定年研究现状、研究热点、研究进程进行科学总结。研究结果表明,Re-Os同位素定年研究总体呈先逐步上升后平稳回落的发展态势。该项技术已广泛应用于钼、铜、钨、金等金属矿床的成矿年代研究,在东秦岭、东天山、冈底斯、东昆仑、大兴安岭、大宝山、小秦岭、豫西、滇西等地开展了大量研究工作,实验检测对象主要包括辉钼矿、黄铁矿、黄铜矿、磁黄铁矿、毒砂等。油气成藏年代学研究领域,已将该项技术应用于川西南乌斯河、南盘江盆地、四川盆地、黔东北梵净山等地的页岩、沥青等定年研究。The study of geological age is the foundation for analyzing geological events.Re-Os isotope dating technology is one of the most important dating techniques in the field of geology.This article aims to find a scientific method to analyze and summarize the research results of Re-Os isotope dating in recent years,sort out the research context and hotspots,and provide reference for the deployment of geological dating research work.The research method is to take 581 literature materials with high relevance to the research topic in the past 30 years(from 1994 to 2023)as the research object,and use scientific knowledge graph analysis technology to draw knowledge graphs such as research author collaboration graph,research institution collaboration graph,research keyword co-occurrence network graph,research topic evolution graph,etc.,to scientifically summarize the current status,research hotspots,and research progress of Re-Os isotope dating research.The research results indicate that the overall trend of Re-Os isotope dating research shows a gradual increase followed by a stable decline.This technology has been widely applied in the study of mineralization ages of metal deposits such as molybdenum,copper,tungsten,and gold.A large amount of research work has been carried out in the eastern Qinling Mountains,eastern Tianshan Mountains,Gangdise Mountains,eastern Kunlun Mountains,Greater Khingan Mountains,Dabao Mountains,Xiaoqinling Mountains,western Henan,and western Yunnan.The experimental detection objects mainly include molybdenite,pyrite,chalcopyrite,magnetite,arsenopyrite,etc.In the field of oil and gas reservoir chronology research,this technology has been applied to the dating study of shale,bitumen,and other materials in the southwest of Sichuan,including the Usu River,Nanpanjiang Basin,Sichuan Basin,and Fanjing Mountain in Northeast Guizhou.
