在得到地化数据的情况下,经过对数正态分布的逐步截尾法剔除特高数据,进行正态分布检验,是可以较为准确的得到元素异常。但是地质情况复杂多变,为了从多种元素中找出最有利于找矿的元素或元素组合,采用SPSS的聚类和偏相关分析是可行的。在得到组合的情况下,将异常合并处理,得到最大的异常区域,并与地质状况相联系,得出正确的地质解释,将为找矿工作提供更准确的信息。
Under the condition of obtaining the geochemical data, the normal distribution test can eliminate the extra-high data through the step-wise truncation method of log-normal distribution, which can obtain the element anomaly more accurately. However, due to the complicated and changing geological conditions, it is feasible to use SPSS cluster and partial correlation analysis in order to find out the most favorable element or combination of elements for ore prospecting among various elements. When the combination is obtained, the abnormal anomaly processing is combined to obtain the largest anomaly area and is associated with the geological conditions to obtain the correct geological interpretation, which will provide more accurate information for prospecting work.
