摘要
勘查数据分析(EDA)技术是一种新的处理数据的非常规统计学方法。本文利用Boxplot图示,通过对山西和新疆某地区的区域地球化学数据的分析,以Boxplot对比为基础确定成矿有利地质体、研究异常元素组合和进行异常评序。结果表明,该方法简单、实用,并能抵抗特高值的影响。
Exploratory Data Analysis (EDA) technique is an unconvential statistical method of data processing.Boxplot graphicaltechnique is used as the method to distinguish the element associations of multi-element anomalies in the paper according tothe regional geochemical data of two regions,one in Shanxi,one in Xinjiang.It is also used to try to do the ranking ofsignificant anomalies and study the distribution of trace elements in time and space so as to identificate favourable geologicalunits.The results proved that Boxplot is a new simple and practical method in the analysis and interpretation of geochemicalexploration data.
