| 深部及外围寻找隐伏金矿体，已成为鲁西铜石地区的找矿重点。大平安庄地区位于铜石杂岩体的东南缘，燕甘断裂东侧，大平安庄断裂带内，北距归来庄大型金矿床约2.5 km。本文在研究铜石地区成矿模式及找矿模型基础上，归纳总结研究区地质、物探、化探、槽探等找矿信息，与归来庄金矿床相似类比，发现二者成矿地质条件相似，Au、Ag元素化探异常、重磁异常等分布规律相近，地表揭露及激电测深均指示大平安庄断裂是岩浆热液的活动场所，这为Au元素的运移和富集创造了条件，断裂附近新发现的金矿化点很好的说明了这一点。该区大平安庄断裂带具有良好的Au成矿潜力，经进一步工作有望实现找矿突破。 |

| Searching for concealed gold ore bodies in the deep and the periphery has become the focus of prospecting in the Tongshi area of western Shandong Province. Daping’anzhuang area is located in the southeast margin of Tongshi Igneous Complex, in east side of Yangan fault，in Daping’anzhuang fault zone，and north distance to Guilaizhuang large gold deposit about 2.5 km.This paper the metallogenic model and prospecting model of Tongshi area are studied. The prospecting information of geology, geophysical prospecting, geochemical prospecting and trough prospecting in the study area are summarized. The study area is compared with Guilaizhuang gold deposit. It is found that the ore-forming geological conditions are close to each other and the distribution of Au and Ag geochemical anomalies, gravity and magnetic anomalies are similar. The surface exposure and Induced polarization sounding both indicate that the Daping’anzhuang fault is the active site of magmatic hydrothermal .uid. This created the conditions for the migration and enrichment of Au. This is well illustrated by the newly discovered gold mineralization near the fault. The Daping’anzhuang fault zone in this area has a good potential for Au mineralization and is expected to achieve a breakthrough in prospecting after further work. |
