特征分析(亦称决策模拟)是一种多元统计分析方法。其基本原理是定量类比,通过建立控制区,分析控矿地质条件的重要性。即查明控制区内变量相互间的相关性,以确定各地质特征的权值,然后与预测区进行相似性的比较,求得联系度,以此来表示预测对象的成矿可能性,并据此圈出有利的成矿远景区。国外用此方法已成功地圈定出勘探靶区,并在探索半隐伏或隐伏矿床方面,已取得了成功的经验。我们通过对镍矿总量预测方法的研究,将特征分析与其它数学方法相结
Feature Analysis (also known as Decision Simulation) is a multivariate statistical analysis method. The basic principle is quantitative analogy, through the establishment of control area, the importance of analyzing the geological conditions of ore control. That is to find out the correlation between the variables in the control area, to determine the weight of each geological feature, and then compare the similarity with the prediction area to get the contact degree, in order to represent the possibility of mineralization of the prediction object According to this circle of favorable prospecting area. This method has been used abroad to successfully delineate exploration targets and to explore successful experiences of semi-concealed or hidden mineral deposits. We through the nickel ore total amount forecasting method research, the characteristic analysis and other mathematical methods
