| 摘 要： | 夏甸金矿床位于胶西北金矿矿集区,成矿作用受区内招平断裂带控制。随着夏甸金矿床找矿工作向深部发展以及地质勘查资料的充分积累,定量化的成矿预测研究成为夏甸矿区深部找矿工作的重要突破点。文章采用面向深部找矿的隐伏矿体立体定量预测原理,基于多源勘查数据构建三维地质模型进行控矿地质因素的三维定量分析,获取反映成矿规律的成矿信息,以多元回归分析方法建立三维预测模型,并应用于夏甸金矿深部找矿。最终得出的相关三维模型和控矿地质因素能为成矿作用研究提供定量的数据支撑,圈定的立体找矿靶区对于夏甸矿区深部找矿具有重要意义。

| Abstract: | Xiadian gold deposit is located in Northwestern Jiaodong gold deposit-cluster area with mineralization controlled by Zhaoping fault. With its prospecting work to depth and accumulation of the prospecting data, quantitative ore prediction research has become the key to make breakthrough for the deep prospecting. Based on the principle of 3D quantitative prediction of concealed ore bodies to depth and multi-source exploration data 3D geological models were built and 3D quantitative analysis of the ore-control factors made to obtain the ore-forming law and ore information, then 3D ore-predicion model built with multi-regression analysis. According to the obtained data 3D prospecing targets are outlined. |
