玲珑金矿田东风矿床深部成矿规律及成矿预测

Metallogenic Regularity and Metallogenic Predication of Deep Orebodies of Dongfeng Gold Deposit in Linglong Gold Field

东风金矿床位于玲珑金矿田内,受招(远)-平(度)断裂下盘次级构造控制。中浅部多以石英脉型为主,深部已渐变为蚀变岩型金矿。该文在系统收集、分析以往矿区勘查开发资料基础上,运用井中激电、测井和构造叠加晕研究,首次建立了东风金矿床构造叠加晕理想模式图,圈定物化探异常区。并利用钻孔对少量异常区进行验证,结果表明物化探异常区与实际见矿位置较吻合,预示该区深部具有较大的找矿潜力。

Dongfeng gold deposit is located in Linglong gold field. It is controlled by secondary tectonic structures of Zhaoyuan-Pingdu fault belt. The shallow part is mainly quartz vein type,and the deep part has been gradually changed into altered rock type gold deposit. On the basis of collecting and analyzing the former information of ore exploration and development,by using borehole induced electric,logging and structural superimposed halo research,ideal pattern of structure superimposed halo in Dongfeng gold deposit has been established for the first time,and geochemical anomalies in the area have been circled. As showed by results,geochemical anomaly area is in good agreement with the actual ore location. It indicates that deep part of the area has great potential for ore prospecting.
