1:20万区域化探采样和样品分析工作的质量评分及质量等级的评定

THE MARKING OF QUALITY AND EVALUATION OFQUALITY GRADE FOR SAMPLE COLLECTION ANDANALYSIS IN 1:200 000 REGIONAL GEOCHEMICALPROSPECTING

根据约50个1:20万区域化探图幅的评审和验收工作,认为目前地矿部存在的少数图幅质量不高的主要原因是采样和分析工作的质量要求不明确、管理不严所致。作者根据地矿部已有经验编写了《1:20万区域化探野外采样、样品加工及原始资料质量评定标准》和《1:20万区域化探样品多元素分析质量验收评分标准》。这两个标准已经过近三年的实践和执行,证明对提高采样和分析工作质量的效果是好的。本文全文发表了这两个标准的内容,以供全国同行参考。

Abstract According to the assessment and the checking and acceptance of some fifty 1:200, 000 regional geochemical prospecting map areas, it is considered that the comparatively low quality shown in a few map areas of MGMR is mainly attributed to the unclear quality requirements and loose management. Based on experience gained by MGMR, the authors have compiled 'Quality Evaluation Criteria for Field Sampling, Sample Processing and Firsthand Data in 1:200, 000 Regional Geochemical Prospecting'and 'Criteria for Marking Mul tielement Analytical Quality in 1:200, 000 Regional Geochemical Prospecting'. Nearly three years' practice demonstrates that these two sets of criteria are affective in raising the sampling and analytical quality. In this paper, they are given in full text for the sake of reference.
