陕西大茅坪铜矿床找矿综合模型研究

THE RESEARCH ON SYNTHETIC ORE-FINDING MODEL OF DAMAOPING COPPER DEPOSIT

陕西大茅坪铜矿床赋存于中元古代碧口群火山岩中 ,是陕西勉略宁三角区西部较典型的铜矿之一 ,对该矿床的研究有助于有效地指导在本区寻找同类型矿床。文中对原生晕分析数据、物探测量数据进行了不同方法的处理 ,在此基础上提出了综合找矿模型。其中对原生晕 ,通过不同方法建立了地球化学背景与异常的概率筛分模型、因子分析及元素组合模型、标准化丰度法及轴向分带模型 ;

The Damaoping Cu deposit in Shaanxi provice occurred in volcano sedimentary strata of Bikou group of paleoproterozoic era.It is a typical copper deposit of MianLuening triangle district.Study this kinds of deposit can make us effectively find same kinds of deposits in this area.The synthetic ore finding models are established with different data processing methods.Data of primary halo,the probality sieve model of geochemical background and anomaly,the factor analysis and elements assembling model,the standardization abundance method and axial zoning model are established;Deal with the geophysical data by mathematics method,the synthetic and geophysical surveying geophysical anomaly are established and forecast minerallization area through application this model.
