| 摘 要： | 本文对1:5万地球化学普查样品中分析元素的选择问题提出了一些应考虑的原则和依据,并例举了我国在化探找矿实践中曾采用且已取得效果的指示元素选用的实例,以供读者在工作中参考。作者根据地矿部各野外队实验室的经验提出了1:5万样品分析的质量监控方法、几项质量参数及这些质量参数的计算式和统计方法。为了客观地评价1:5万化探样品分析的质量等级,文章提出了“优秀”、“良好”、“及格”和“不及格”四个质量等级和它们相应的质量参数。

| Abstract: | This paper presents some principles and bases which are worth considera-tion in the selection of analytical elements for samples collected in1:50,000geochemical reconnaissance, and, for reader's reference, gives examples about theselection of indicator elements which has been proved to be effective in ore-prospecting practice. Based on expelience gained by laboratories of various geo-logical parties belonging to Ministry of GeoJogy and Mineral Resources, theauthor puts forward a quality-monitoring method for the analysis of 1:50,000samples, several quality parameters and their calculation formulae and statisti-cal techniques. In order to make an objective evaluation of the analytical qua-lity of 1:50,000 geochemical samples, the present paper suggests four qualitygrades (excellent, good, passable and substandard) and their respective qualityparameters. |
