摘要
本文介绍应用判别分析的原理制作化探推断性图件——判别计量图和判别异常图的成图方法。这种成图方法以充分提炼原始找矿信息的综合指标Ri,(Png/x)表征异常,与传统成图方法相比,不仅大大减少了成图工作量,而且具有强化矿致异常、压抑干扰、反映异常源的性质、区分矿化类型等优点。
This paper presents a new cartographical method of making the interpretation map of the geochemical exploration results (termed discriminant score map and discriminant anomaly map) based on the principles of the discriminatory analysis. This method can be used to indicate anomalies with the comprehensive index (Ri, Pπg/x) , which may fully extract the original prospecting information. Compared with the traditional cartographical method, this one can not only reduce the work amount of charting, but also posses the advantages of enhancing the anomalies due to orebodies, despressing the disturbance, reflecting the nature of anomaly source, and distinguishing the mineralization patterns.
