摘要
据 1998年两报刊报道 ,浙江龙游虎头山发现一粒 1/ 5米粒大小的金刚石 ,并确认含该金刚石的岩石为金伯利岩。笔者根据该岩体岩石性质、岩体产状、岩石化学成分、特征矿物组合等特征 ,初步推断该岩石为角砾状超基性岩 ,原岩恢复为橄辉云煌岩 ,而不是金伯利岩 ,也不是钾镁煌斑岩。
It was reported in 1998 by the newspapers 'Science and Technique Ribao' and 'Yangtze Wanbao' that kimberlite had been discovered in Hutoushan of Longyou county,Zhejiang. Based on study on attitude,texture and structure,typomorphic minerals,petrochemical composition of ultrobasic rocks in this region,it is concluded that ultrabasic rocks in this area should be cascadite breccia,not kimberlite or lamproite.
