摘要
利用区域地球化学勘查数据 ,经过窗口滑动平均 ,计算出滑动窗口的衬值 ,通过衬值圈定单元素和多元素累加 (累乘 )异常 ;在窗口滑动平均值基础上勾绘单元素和多元素背景曲线图、累加 (累乘 )多元素衬值异常和背景曲线图 ,制作找矿靶区定位预测图。
Using regional geochemical exploration data, the authors figured out moving window contrast values through window moving average operation,delineated single element anomalies and multi element accumulative (multiplicative) anomalies according to contrast values,and drew single element and multi element background diagrams,accumulative (multiplicative) multi element contrast anomalies and background diagrams,which make up the locating prognostic chart for the ore prospecting target. The effects of its application in Xinjiang and a certain ore belt in Qinba area are described in this paper.
