应用数量化理论对集安复兴屯矿田矿产预测变量研究

Applying theory of quantification to study prediction variables of mine product for Fuxingtun mineral deposit in Jian area

本文结合集安复兴屯矿田1:25万矿产预测资料,采用网格单元在确定训练区和预测区的基础上,对于其中矿产预测地质变量、地球化学场、地球物理场的特征进行详细研究并对定性地质变量以0-1赋值法对其赋值,运用数量化理论Ⅲ进行计算分析,取前三个因子的标度因子得分对区内的地质控矿因素进行分析,从而从定量上为集安复兴屯矿田矿产预测变量的选择提供了依据.

In this paper, the geological variables of mineral product prediction, character of geophysical field and character of geochemical field are studied in detail by analyzing of mine prediction information at scale 1 ： 250000 for Fuxing mine deposit. Based fixing on training zone and predicting zone by using raster unit, the qualitative geological variables are given 0 or 1, and then, the geological variables are calculated and analyzed by using Theory of quantification m. The factors of controlling mineral deposit in the area are analyzed according to scores of fore three criterion factors produced by Theory of quantification III. And thereby the evidences of mineral product prediction are quantificationally provided for Fuxingtun mineral deposit.
