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.
