摘　　要：宝玉石产地来源的研究是近几年地质学、宝石学和考古学界的热门话题之一。一方面,不同产地来源的宝玉石可能具有不同的品质特征及经济价值,其研究有助于珠宝首饰价值的判断,为各国海关执法提供技术支持;另一方面,古代宝玉石产地的确定对了解古代宝玉石的开采与古代科技的发展水平及不同区域的文化交流均具有重要意义。在总结前人研究成果的基础上,结合现代微区测试技术的最新研究成果,从微量元素、包裹体以及同位素分析等方面探讨总结了微区测试技术在确定宝玉石产地来源研究中的应用。当前的研究结果显示,不同的技术方法对确定宝玉石的产地来源均有一定的意义,但宝玉石产地来源的最终确定往往需要依赖更大范围和更深入地对宝石矿床的地球化学进行多技术手段的交叉分析。显然,确定各种不同类型宝玉石产地来源的标型特征及建立相关重要宝石产地的地球化学数据库,是最终解决宝玉石产地来源鉴定问题的关键。Research on the origin and occurrence of gems and jades is one of the hottest topic in geology, gemmology and archaeology. On the one hand, gems and jades of different origin may have different quality, characteristics and value, and the research on the origin and oc- currence can be helpful to the appraisal for the jewelry, providing the technological supports to the Customs. On the other hand, the determination of the occurrence is of great significance to find out the ancient gem mining as well as the development of science and technology of the ancient and cultural exchanges between different regions. By summing up the previous studies and combining with the latest researches on the modern microanalysis,the application of microanalysis in study of the origin and occurrence of gems and jades is summarized on the aspects of trace elements, inclusions and isotopes in this article. The current studies show that the different techniques are of a certain significance to determine the origin of the gems and jades, while finalizing origin often deeply and widely relies on the cross analysis on the geochemistry of gems, by using various testing techniques. Obviously, it is the key to the fi- nal settlement of the typomorphic characteristics of the origin and occurence of the different gem types and establishing a geochemical database of important mines.
