目前在地球化学找矿方面,随着区域性化探普查工作以及地球化学编图预测工作的开展,很多国家采用标准参考试样来监控分析质量.最近,冶金地质化探标样的制备工作也已开始,故将美国有关制备六个地球化学找矿参考试样的情况介绍一下,以供参考.美国地质调查所,很早就采用了统一的国际标准参考试样控制化探分析质量,在第一套试样消耗完时,于1970年又组织了第二套六个地球化学找矿参考试样(简称GXR试样),到1974年,每个参考试样均完成42 At present, in geochemical prospecting, with the regional geochemical census and geochemical mapping prediction work, many countries use standard reference samples to monitor the quality of the analysis.Recently, the preparation of metallurgical geochemical probe standard Has begun, so the United States about the preparation of six geochemical prospecting reference sample introduced for reference purposes, the United States Geological Survey, has long adopted a unified international standard reference sample control the quality of geochemical analysis, in When the first sample was consumed, a second set of six geochemical prospecting reference samples (GXR samples) were organized in 1970, and by 1974 each of the reference samples was completed 42
