| 摘 要： | 西藏的铬铁矿产出主要受超基性岩体的控制,文中通过对西藏54个超基性岩体化探数据中5种氧化物成分的聚类与判别分析,根据已知的22个岩体的含矿性预测出未知的32个岩体的含矿性,并对比两种分析方法的效果,指出判别分析所预测的含矿岩体结果是具有较高的可信度的。

| Abstract: | Chromite mineralization is mainly controlled by ultrabasic rock in Xizang.This paper used the five main rock-forming oxide content of fifty-four ultrabasic rocks in Xizang.Through the cluster analysis and distinguishing analysis of this date,Forecasting if the thirty-two unknown ultrabasic rocks have mineralization or not by the ultrabasic rocks which have been confirmed to have mineralization or not.According to the contrast of results of the two kinds analysis methods,It points out that the result of havi... |
