摘要
本文对研究区内接触交代—岩浆期后热液型铁、铜多金属矿床系列的成矿、控矿地质条件进行了定量描述,建立了矿床系列的定量模型,探索出一套适合于矿床矿化系列的资源评价系统方法。
Based on the theory of mineraogenetic series and mineralization series,the author has undertaken a practical research on quantitative evaluation of mineral resources.The classifica- tion principle on the statistical unit of ore-forming or ore-controlling geological bodies has been set up and the unit range has been confined.The paper also studies the sellection of variance. by C-D correlation coefficient and quantity of information,and the function of variance from two aspects.The sellected optimal variance set is composed of the variance which pocesses double function.In order to guarantee the typicality and exponent of mathematical model. quantification theory-Ⅳ and the calculation of sample imformation content are used to sellect the samples of standard unit which will join into the model,which will make the scale value of model sample vary with deposit value.It is very useful to carry out the charater-analysis and character vector,monotone coefficient and direction coefficient analysis in the quantitative evaluation of mineralization series resources.
