| 摘 要： | 在全面搜集研究已有资料的基础上,详细阐述了近年来山东省金矿勘查取得的主要成果,并系统总结了成矿理论和成矿规律研究方面的新进展。近十年来,山东省金矿勘查取得重大进展,仅在胶东地区,就累计发现大中型及以上金矿70多处,其中超百吨的特大型金矿床6处,均分布在招远-莱州整装勘查区内。此外,在牟乳成矿带发现了新类型的辽上式大型金矿——黄铁矿碳酸盐脉型金矿,资源储量70 t;发现笏山-西陡崖金矿,资源储量超过30 t,极大地扩展了胶东地区的金矿找矿范围。同时,在鲁西地区归来庄矿田隐爆角砾岩型金矿深部600 m以下发现新矿体,新增资源储量超过20 t;在鲁西莱芜地区发现三岔河矽卡岩型铁金矿床,资源储量近7 t;在泰安新泰市化马湾附近发现了泉河金矿床,这显示着鲁西地区同样具有广阔的深部找矿前景。在成矿作用研究方面,针对成矿作用机制、成矿模式及矿床类型等不同方面,地质学家们也提出了诸多理论学说,对促进山东金矿找矿突破发挥了重要的指导作用,进一步推动了山东金矿理论创新和找矿实践。

| Abstract: | Based on comprehensive collection of the existing data, this paper introduces the main achievements of geological exploration of gold deposits in Shandong province in recent years, and summarizes the new progress in the research of gold metallogenic regularity and theory. In recent years, significant breakthrough had been made in exploration of gold deposits in Shandong province, and over 70 middle-large size gold deposits had been discovered, six of which are super large with reserves of above one hundred tones and mainly locate in Zhaoyuan-Laizhou areas. In addition, a large size Liaoshang- type gold deposit with a reserve of about 70t, a new type which characterized by pyrite-carbonate veins, had been discovered in Muru metallogenic belt, and the discovery of Hushan-Xilindouya gold deposit with a reserve of about 20t had considerably enlarged the scope of gold prospecting in Jiaodong area. At the same time, 600-meter-deep orebodies with a reserve of over 20t had been found in Guilaizhuang cryptoexplosion breccia type gold deposit in Western Shandong, Sanchahe skarn-type Fe-Au deposit with a reserve of about 7t had been discovered in Laiwu area, and Quanhe gold deposit had been discovered in Mawan area in Xintai city. These new discoveries indicate that there is a very good prospecting perspective in the depth in Western Shandong. Geologists had put forth many metallogenic theories about metallogenic mechanism and model in the research of metallogenesis. These theories played an important role in the breakthrough of exploration of gold deposits in Shandong province, and promoted the theoretical innovation and exploration of gold deposits in Shandong province. |
