海南岛1:20万区域化探样品分析工作方法介绍

WORKING METHOD FOR THE ANALYSIS OF 1:200 000REGIONAL GEOCHEMICAL SAMPLES IN HAINAN ISLAND

本文是1986年地矿部组织的海南岛1:20万区域化探跨省承包项目中有关由五个实验室联合承包全岛样品分析工作的经验总结。文章系统介绍了他们对数据的报出和报出率、I、II级标样的监控、内部检查、密码抽查等质量参数的认识和质量监控方法方面的经验。这些认识和经验对于目前正在进行1:20万区域化探样品分析的各省局实验室和承担拼图编图任务的物探队,特别是由几个实验单位共同承担本省样品分析任务的实验室如何保证检品分析质量的问题上可能有参考价值。

Abstract This paper is a. summarization of experience gained in the analysis of samples from the whole island undertaken jointly by five laboratories in the transprovincial contract project for 1:200,000 regional geochemical prospec ting of Hainan Island organized in 1986 by Ministry of Geology and Mineral Resources. It deals systematically with the understanding of such quality para meters as detection proportion, monitoring of standard samples of Grade I and Grade II, internal check and cipher sample check as well as the ex perience acquired in quality monitoring. In the aspect of how to guarantee the analytical quality, these understand ing and experience are probably of referential value to geologic laboratori es of various provinces which are performing analysis of 1:200,000 regional geochemical samples, geophysical parties which are undertaking the task of piecing together and compiling maps and, especially, laboratories which are jointly charged with the analysis of samples from the Hainan province.
