【摘要】：四川甲基卡新三号(X03)超大型锂矿脉是近年发现且价值巨大的锂矿化伟晶岩脉,但相对缺少地球化学的研究,利用ICP-MS测试手段对该矿脉ZK1101钻孔中44件样品进行分析测试,发现该矿脉稀土总量很低(∑REE为0.180×10~(-6)~8.613×10~(-6),平均值为2.543×10~(-6)),配分曲线呈右倾斜型,相对富集轻稀土,总体表现铕负异常.围岩的稀土含量与一般片岩相近(∑REE为160.134×10~(-6)~265.881×10~(-6),平均值为230.718×10~(-6)),稀土配分曲线总体呈右倾平滑趋势,富集轻稀土,铕为负异常.铕的分布具有特殊性,表现为铕在伟晶岩脉的边部具有显著的正异常.∑REE与Li呈负相关性,δCe与Li则表现为弱正相关性.这一首次发现的低稀土总量和矿脉边部Eu显著正异常的特殊性,对于甲基卡伟晶岩的含矿性评价可能具有重要意义.
