摘要
本文导出了通过控矿地质因素逻辑信息法的研究来建立矿化富集中心数学模型的公式,使矿化富集中心数学模型与控矿地质因素定量地联系起来。还给出了单个矿化富集中心趋势面分析的数学模型和矿床空间分布模型。在这基础上,以某锡-多金属成矿带中某远景区的研究为例说明怎样应用矿化富集中心地质因素多元统计分析（逻辑信息法、趋势面分析、逐步回归分析和聚类分析）进行矿床统计预测。
In this paper the author has derived the formula of establishing mathematical model of enriched mineralization centre by means of logic information method of ore-controlling geological factors. It associates quantitatively the mathematical model of enriched mineralization centre with ore-controlling geological factors. Simultaneously this paper has given the spatial distribution model of ore deposits and the mathematical model of trend surface analysis of single enriched mineralization centre. Based on the above mentioned study, taking a prospective area of the tin-polymetallic mineral belt as an example, the paper illustrates how to applicate multivariate statistical analysis of geological factors (logic information method, trend surface analysis, stepwise regression analysis and cluster analysis) to make statistical prediction of ore deposits.
