| 中文摘要:大尹格庄金矿是胶西北招平断裂带中段的大型金矿床, 但随着逐渐的开采其保有资源量不断下降, 急需在矿床的深边部区域开展接续资源找矿工作。本文以大尹格庄金矿为研究对象, 以区域成矿理论和找矿勘查模型为指导, 利用三维地质建模技术构建了相关地质体的三维模型, 在此基础上, 采用定量化的方法提取地质体与成矿相关的控矿因素指标和矿化指标, 并建立了三维定量成矿预测模型, 并应用该模型圈定了3个找矿靶区。研究表明, 该方法能够适用于大中型矿山的深边部找矿工作, 其三维及定量化的预测结果能够为后续的勘探及开采工作提供重要参考。 |

| Abstract:The Dayingezhuang gold deposit is a large-sized gold deposit in the middle of the Zhaoping fault zone of northwestern Jiaodong. However, with the continuous exploitation of its retained resources, it is urgent to carry out the prospecting work in the deep and lateral parts of the deposit. Taking the Dayingezhuang gold deposit as the research object, the authors used the three-dimensional geological modeling technology to construct the three-dimensional model of the relevant geological body based on the regional metallogenic theory and prospecting exploration model. On such a basis, the quantitative method was adopted to extract the ore-controlling indicators and mineralization indicators. The three-dimensional quantitative metallogenic prediction model was established. Three prospecting targets were delineated by the model. The results show that the method can be applied to the deep and lateral prospecting work of large and medium-sized deposits, and its three-dimensional and quantitative prediction results can provide important reference for subsequent exploration and mining work. |
