摘要:

利用最小二乘法分别对湖南龙山金锑矿区41~46线126件地电化学(泡塑)法样品中Au和Sb,阳山矿区和寨上矿区偏提取样品中金与砷锑汞的综合异常(As-Sb-Hg)进行了线性相关性统计检验,得到的相关系数分别为0.895和0.859,均大于临界值0.811,表明Au与伴生元素显著相关。检验结果与已知的矿区地球化学元素异常组合特征相吻合,以此作为评估分析质量的依据,认为分析结果可靠。在没有合适标准物质或重复样监控情况下,提出了化探分析元素相关性质量评估方法,有利于地球化学找矿新技术、新方法的推广应用。

关键词: 相关系数, 地电化学(泡塑), 偏提取, 质量评估

Abstract:

 Based on the least square method,linear correlation and statistical tests between Au and Sb determined by geoelectric chemistry method in 126 samples of line 41 to 46 at gold-antimony orefield in Longshan,Hunan Province.The same analysis was also conducted between integrating anomaly characteristics of Au and As-Ab-Hg that separated by sequential extraction.The obtained correlation coefficients were 0.895(Au and Sb) and 0.859 (Au and As-Ab-Hg),respectively,bigger than the critical value(0.811),suggesting the significant correlation between gold and associated elements.The test results were in good agreement with known combination features of the abnormal geochemical element in the mining,which can be applied for analysis of quality evaluation. Therefore,it is considered that the analysis results are reliable.Under the conditions without appropriate standard substances or duplicate sample monitoring,geochemical analysis element correlation evaluation method was proposed,which is advantageous to the geochemical prospecting popularization and application.

Key words:  correlation coefficient, geoelectric chemistry, sequential extraction, quality evaluation
