各种地质样品的分析越来越需要标准样来监控分析的质量[1,2]。标准样还可作为鉴定新的分析方法的依据和分析测试(特别是仪器分析)的校正标准。地质部已把研制各类地质物质的标准样品作为地质实验分析和地球化学工作的一项基本建设,纳入了科研计划。地质部标准参考样研究组承担了以痕量元素为主要对象的地球化学探矿标准样的研制。为了满足全国
The analysis of various geological samples is increasingly in need of standards to monitor the quality of the analysis [1,2]. Standards can also be used as a basis for identifying new analytical methods and analytical testing (especially instrumental analysis) calibration standards. The Department of Geology has put standard samples of various types of geological materials into consideration as a basic construction of geological experimental analysis and geochemical work and has incorporated scientific research plans. The Department of Geological Standard Reference Reference Group has undertaken the development of geochemical prospecting standards with trace elements as the main target. In order to meet the nation
