摘要
1:20万区域化探由于采样和分析方法的差异,各图幅间数据中存在着明显的系统误差和随机误差,大范围内的资料研究先要进行误差处理。在消除各种误差对Au元素含量数据影响的基础上,对阿尔泰地区成岩、成矿相关的Au元素地球化学特征信息进行了初步研究。
For the 1:200 000 regional geochemical prospecting word, the difference produced by sampling and analysis method. makes a considerable error of the data of the interval of map sheets.The error correcting work should be done foy the date from a large scale region.After eliminate the different error effect on the content of An element, this paper puts forward a preliminary study on the information of geochemical characteristics re lated to the diagenesis and metallogenesis.
