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 ;对物探数据进行线性加权组合建立了综合物探异常并运用该模型进行了初步预测
The Dapingping copper deposit in Shaanxi Province is hosted in the volcanic rocks in the Middle Proterozoic Bikou Group and is one of the more typical copper mines in the western part of the Triassic Ningxia Mianlening, Shaanxi Province. The study of this deposit can effectively guide the search for the same Type of deposit. In this paper, the primary halo analysis data and geophysical survey data are processed by different methods, and based on this, a comprehensive prospecting model is proposed. For the primary halo, probabilistic screening model, factor analysis and elemental combination model, normalized abundance method and axial zonation model of geochemical background and anomaly were established by different methods. The geophysical data were weighted by linear combination to establish a comprehensive geophysical prospecting Abnormal and use the model for a preliminary prediction
