【摘要】 自原国土资源部等四部委发布《找矿突破战略行动纲要(2011—2020年)》,山东加强了对蒙阴金刚石原生矿深部及外围的勘查,深部及外围找矿工作取得丰硕成果,并在金刚石找矿方法和综合研究方面取得改进和新认识。本文总结了10年来山东省第七地质矿产勘查院金刚石找矿成果,蒙阴常马庄和西峪金刚石原生矿深部钻探控制至1000m,新增金刚石矿物量550万ct,改进了金刚石原生矿重砂矿物组合和粒级,完善了金刚石找矿方法和选矿方法,对金刚石成矿理论取得新认识,并在深部新发现含金刚石的金伯利岩管,在蒙阴金刚石原生矿外围发现了含金刚石的煌斑岩,查明了费县朱田大井头岩管为含金刚石的钾镁煌斑岩岩管。编制了《矿产地质勘查规范金刚石》,填补了我国没有《金刚石矿勘查规范》的空白,对我国今后的金刚石矿勘查具有重要的指导作用。更多还原

【Abstract】 Since the "strategic action outline for prospecting breakthrough(2011—2020)" issued by the original Ministry of Land and Resources and other four ministries, exploration of the deep and peripheral areas of Mengyin primary diamond deposit in Shandong province has been strengthened, many achievements have been gained in deep and peripheral prospecting work, and improvements and new understanding have been gained in diamond prospecting methods and comprehensive research. Diamond prospecting achievements which have been gained by No.7 Exploration Institute of Geology and Mineral resources in the past ten years have been summarized comprehensively. The deep drilling of Changmazhuang and Xiyu primary diamond deposits in Mengyin has been controlled to 1000 m, the amount of diamond minerals has been increased by 5.5 million ct, the mineral assemblage and grain size of heavy sand in primary diamond deposits have been improved, the diamond prospecting method and mineral processing method have been improved, and the new understanding of diamond metallogenic theory has been obtained. It is found that Dajingtou rock pipe in Zhutian of Feixian county is a K-Mg lamprophyre pipe containing diamond. The "geological exploration norm of diamond" has been compiled, which fills the blank of "norm for diamond exploration" in China, and plays an important role in guiding the future diamond exploration in China.更多还原
