在华北地台太古宙高级变质区和花岗岩，绿岩带内系统采集了变质杂岩体和变质火山岩样品２７７５个，组合成３３９件分析样，采用１５种分析方法对样品进行测试，同时由国际公认的国家一级地球化学标准物质监控分析质量，提出了华北地台长英质片麻岩、变粒岩、麻粒岩和斜长角闪岩２６种变质岩类１３个主成分和６４种微量元素的平均含量 A total of 2775 metamorphic complex and metamorphic volcanic rocks were collected from the Archean high-grade metamorphic area and granite and greenstone belts in North China, and were combined into 339 samples for analysis. Fifteen kinds of analytical methods were used to test the samples. At the same time, It is generally acknowledged that the monitoring quality of geochemical reference materials at the national level is high, and 13 main components and 26 species of 26 metamorphic rocks from the North China Platform are represented by gneiss, granulite, granulite and plagioclase amphibolite The average content of trace elements
