数学地质在矿山研究中的应用——判别分析归类矿体属性实例

The application of mathematics geology for the mine study-a concrete example of the discriminant analysis for ore body classification

数学地质方法为宏观地质研究提供了定量的可能。判别分析对研究未知属性矿体的归属有着重要的意义。苏州西部地区通安—潭山多金属成矿带中,小茅山铜铅锌矿段,潭山铅锌银铁矿段位于成矿带的两端,属性已知。该成矿带中有一未知属性的铜铅锌银迂里矿段,用判别分析方法对其归类。研究结果表明,未知属性的迂里矿段归属潭山多金属硫化物矿床类型,即高—中温多金属硫化物矿床类型。

The geological method of mathematics offers the quantitative possibility for studying in macroscopical geology. The discriminant analysis has an important significance for orebody classification. The Xiaomaoshan copper lead zinc mine, Tanshan lead zinc silver iron mine are located in the two ends of metallogenic belts, in the west Tongan--Tanshan polymetallic metallogenic belts, Suzhou, which the nature of rocks has been known. In this metallogenic belt, there is unknown nature of rocks in the Yuli copper lead zinc silver mine, it was classified using the discriminant analysis method. The result shows that it belongs to polymetallic sulphide deposit type, namely high- middle temperature polymetallic sulphide deposit.
