(一)为什么要建立化探管理(标准)样? 化探是地质找矿过程中的一个重要手段,特别是在区测普查中效果尤为显著,但由于我国目前广为采用的半定量分析(特别是光谱)本身往往有很大系统误差,不但不同单位的分析结果对不起来,就是同一单位不同时期进行分析的结果也不易相符,致使化探资料不好对比研究,图件不能拼连,在一定程度上限制了化探效果的发挥和化探技术
(A) Why geochemical exploration management (standard) like? Geochemical exploration is an important means of geological prospecting process, especially in the regional survey results are particularly significant, but due to the widely used semi-quantitative analysis ( Especially the spectrum) itself is often a large systematic error, not only different units of the analysis can not up, that is, the same unit in different periods of the results of the analysis is not easy to match, resulting in poor comparative study of geochemical data, maps can not fight together, in the To a certain extent, limit the play of geochemical exploration and geochemical exploration techniques
