| 摘 要： | 金刚石形成于地幔深处 ,含金刚石的岩石只是一种运载和保存“工具” ,凡是来自上地幔的岩石均有可能携带早已形成的金刚石而形成金刚石原生矿床。世界上已知金刚石原生矿除金伯利岩、钾镁煌斑岩型外 ,尚在橄榄岩、橄榄玄武岩、千枚岩、科马提岩、榴辉岩等岩石中发现了金刚石 ,可能存在金刚石原生矿新的岩石类型。山东位于华北地台的南东部 ,鲁西、鲁东基底属A型克拉通 ,幔源岩浆活动强烈 ,具备良好的金刚石原生矿成矿地质条件 ,已获得的大量的成矿信息和找矿线索表明 ,除已发现的蒙阴金伯利岩型金刚石原生矿外 ,应该存在着尚未发现的金刚石原生矿 ,找矿前景广阔 ,应进一步加强金刚石原生矿勘查工作。

| Abstract: | Shandong province locates in southeast part of Huabei platform. Substratum of Ludong (east of Shandong) and Luxi (west of Shandong) belong to A type craton. Magma from mantle activated strongly which possess good diamond primary ore-forming condition. As proved by lots of already gained ore-forming information and clues, not-found diamond primary ores exist except already found kimberlite type diamond primary ore in Mengyin. It has a bright ore-forming future, and exploration work of diamond primary ore should be strengthened further. |
