| 摘 要： | 山东沂南金矿床是鲁西地区典型的夕卡岩型矿床,历经50余年的开采,后备资源储量严重不足。文章借助危机矿山矿产预测项目,在成矿系统理论指导下,通过对已有资料二次开发,深入分析了矿床成矿地质条件和控矿因素,总结了成矿规律。并在大比例尺路线地质调查和地质填图的基础上,在矿区外围选定了2个预测靶区,结合有针对性的地、物、化等综合方法进行了成矿预测,经钻孔验证于不整合面发现工业矿体,为矿山开辟了新的接替资源基地,有效延长了矿山服务年限。2个预测靶区验证钻孔成功见矿,尤其是不整合面见矿的事实,不仅表明沂南金矿深、边部巨大的成矿潜力,对指导沂南金矿深部、外围乃至鲁西地区找矿勘探具有重要意义。 |

| Abstract: | As a typical skarn deposit in the western Shandong Province, the Yinan gold deposit is becoming a serious crisis mine after more than 50 years of exploitation. The serious shortage of reserves turns the search for succeeding resources into a top priority. Relying on the project of mineral resource prediction on crisis mines, under the guidance of metallogenic system theory, the authors collected and repeatedly developed a large number of geological data, according to which the metallogenic geological conditions and ore-controlling factors were comprehensively analyzed, and the metallogenic laws were summarized. On the basis of large-scale traverse geological survey and geological mapping, two forecast targets were selected in the periphery of the mining area. Combined with metallogenic prediction using targeted comprehensive methods including geology, geophysics, geochemistry, etc., industrial ore bodies had been found on the unconformity surface, providing new bases of succeeding resources for the mine and prolonging the mine life effectively. Successful ore-finding by drill-verifying in two predicted targets, in particular, the discovery of the unconformity related mineralization, not only suggests the huge ore-forming potentials in deep and periphery of the Yinan deposit, but also is of great significance to the study of metallogenesis and exploration both in the mine and in the entire western Shandong Province. |
