    摘要:

    本文在前人工作基础上,综合近年来山东国土、地矿、黄金、冶勘、核工业、武警等行业取得的找矿科研成果,详细介绍了山东省金矿床的成矿地质背景和地质特征,系统总结了近年来山东省金矿在找矿突破、成矿规律及找矿方法方面的主要进展,并初步指明了山东省金矿下一步的找矿远景和找矿方向。作为国内外知名的金矿大省,山东省金资源储量和产量均居全国第一位。在找矿突破方面,胶东地区自2011年找矿突破战略行动实施以来,在三山岛、焦家和招平等重要金矿带连续实现找矿重大突破,新增资源量2500余吨,累计查明资源储量已达4500多吨。近年来,在鲁西地区归来庄矿田隐爆角砾岩型金矿深部600米以下发现矿体,预计新增资源储量超过20吨,归来庄金矿将成为鲁西资源量大于50吨的唯一特大型金矿床,也显示着该矿田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。这些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。在勘查技术方面,也由早期的常规方法技术,发展为现今的高精度、大探测深度找矿方法技术。

    Abstract:

    On the basis of previous researches, and combined with the geological achievements in scientific research and prospecting breakthroughs about the gold deposits in Shandong in recent years, this paper summarizes systematically the regional metallogenetic regularity, prospecting method, regional metallogenetic regularity of the gold deposits and gold prospecting guidance in Shandong. As a worldfamous gold provience, Shandong Province is the richest one in gold resources and gold production regions in China. In recent 5 years, particularly after National exploration and development planning (2011), Jiaodong area has made a significant progress in gold ore prospecting. In Sanshandao, Jiaojia and Zhaoping important gold ore belt have made continuous prospecting breakthroughs, the new gold resource of more than 2500 tons, has identified resources reserves has reached more than 4500 tons.In recent years, the exploration of explosion breccia type gold deposits has achieved great progress in the deep part (<-600m) of Guilaizhuang gold deposits in Luxi area(west of Shandong), with the new gold resource of more than 20 tons. Guilaizhuang gold deposit will be the only super large gold deposit in Luxi area. It is believed that there is a good potential for exploring gold mineral resources in depth of this area. In metallogeny research, various the ores of the mechanism of mineralization, metallogenic model and ore deposit types was put forward by global geologists in recent years. This theory and viewpoint bear great in sights for prospecting breakthroughs and the theory in novation of the gold deposits in Shandong. And the exploration technology has already turn to the high precision, large detection depth prospecting methods and techniques from the conventional method of early technology.
