| 摘 要： | 山东费县大井头地区第四系中金刚石及其指示矿物分布异常丰富 ,并且具有较高的集中度 ;该区的加里东期超基性火山碎屑岩、沉火山碎屑岩及其他一些岩石中均有金刚石和 (或 )指示矿物存在 ;该地区的铬铁矿异常属于矿致异常。研究证明该区第四系中金刚石指示矿物与当地的相关岩体关系密切 ;加里东期超基性火山碎屑岩某些特征与火山口相金伯利岩十分相似。大井头地区所处的构造位置有利于金刚石成矿 ,具有良好的找矿前景 ,值得进一步研究探索。

| Abstract: | Distribution of diamonds and its indictor minerals are very abundant in Quaternary Dajingtou area in Feixian county, Shandong province with a high concentration degree; diamonds and its indicator minerals also occurred in Caledonian super-basic pyroclastic rocks, sed pyroclatic rocks and other rocks. Local chromite anomaly caused mineral anomaly in this area. As proved by study, Quaternary diamond indicator minerals have a close relation with related rocks in local area; and Caledonian super-basic pyroclastic rocks have similiar characteristics with crater facies kimberlites. Structural location of Dajingtou area is favor to diamond-formig, which has a good ore-forming future. |
