| 摘 要： | 以马脑壳金矿为例,运用判别分析方法对核物探探测异常进行定性判别研究。通过SPSS软件运用费歇判别和逐步判别两种分析方法,定性非矿异常准确率分别达到83.3%和66.7%,定性有矿异常准确率分别达到89.7%和91.4%。

| Abstract: | With the KNM gold ore deposit as an example,the authors carried out qualitative discrimination of nuclear geophysical anomaly by using discriminant analysis composed of canonical discriminant and stepwise discriminant analysis.Discriminant analysis was employed for gold prospecting,while SPSS software was used for data analysis.It is found that,with these two means,accurate characterization of barren anomalies reaches 83.3% and 66.7% respectively,while accurate characterization of ore-related anomalies reac... |
