| 摘 要： | 实施国际地球化学填图项目最关键的是分析问题。欧洲和中国在全球尺度地球化学填图做法上存在较大的差异。中国使用统一的采样介质,即泛滥平原沉积物,并使用几种大型设备作为骨干配合使用多方法分析系统,分析76种元素,这是人类历史上首次制作了元素周期表上除惰性气体元素和人工元素以外的几乎所有元素地球化学图。欧洲恰恰相反,欧洲在采样介质上趋向于多介质,而分析技术上只使用少数几种大型设备;分析方法的单一,使得很多关键元素没有分析出来,如贵金属元素Ag,Au,Ir,Os,Pd,Pt,Rh,Ru;卤族元素F,Cl,Br,I;分散元素Ge,In,Se,Te;与生命密切相关的元素K,N,S,B等。尽管欧洲强调以环境为目的,但很多与环境密切相关的元素都没有分析,所以欧洲的全球尺度地球化学填图的信息量大打折扣。这些不统一的做法,将会制约全球地球化学图的编制。

| Abstract: | The key problem is analytical problem in accomplishing international geochemical mapping project.Rather big difference exists between China and Europe in global geochemical mapping.The main differences are that uni-medium sampling in flood plain method is used in China while,in Europe,samples are taken from multi-media.Besides,large equipments are used to analyze 76 elements with the assistance of multiple analytical systems in China while only a few large instruments are used in Europe.Multi-media sampling used in Europe has obtained more information of elemental distribution in more natural materials,but it provided less element information because some key elements are not determined,which include Ag,Au,Ir,Os,Pd,Pt,Rh,Ru,F,Cl,Br,I,Ge,In,Se,Te,K,N,S,B,La,Bi,and Sc etc.These differences may restrict the compilation of the whole global geochemical atlas. |
