摘　　要：文章基于对崤山矿集区成矿要素的相关性χ2检验,证实该区域金矿脉的分布与太古宇隐伏岩浆岩、北东向断裂、北西向断裂、环形构造以及金银铅的化探异常具有高相关性,该类地质要素指示了金矿储矿地质特征。文章厘定了崤山矿集区成矿流体包裹体特征、稳定同位素特征、成矿年龄及其与地质构造事件的耦合关系,在对矿床成因分析的基础上绘制了崤山矿集区的成矿模式图,建立了预测模型,并基于MORPAS平台的证据权重法绘制了矿化潜力图,结果显示异常区与已有的矿脉分布吻合度高,明确了下一步的重点工作区域。Based on chi-square correlation test result of mineralization factor in the Xiaoshan gold polymetallic district, it was conclused that the spatial distribution of gold veins are highly assoiciated with the Archean strata, shallow buried igneous rocks, north-east trending structures as well as ring structure lead geochemical anomalies of gold, silver and lead elements. All of these geological elements indicate the geological features of Xiaoshan gold polymetallic deposit. The paper analyzed ore-forming fluid inclusions, stable isotope characteristics and mineralization age, the coupling relationship between tectonic events and mineralization process was delineated. On the basis of genesis study, the metallogenic model prediction model were constructed, and the mineralization potential map was drew up based on the weight of evidence analysis and features by MORPAS platform, the result shows the abnormal area matches highly with the existing distribution of gold veins and further prospecting areas were highlighted.
