1.
Collecting rock samples from several mafic-ultramafic intrusions in Longshou Mountains and studying the petrochemical compositions,trace elements,rare earth elements,combining with the Sr-Nd isotopes of Jinchuan ultramafic intrusion,the authors compare the geochemical characteristics of typical mafic-ultramafic rocks in Longshou Mountains.
通过龙首山岩带中几个典型镁铁-超镁铁质岩体样品的岩石地球化学分析,对金川超镁铁质岩体与其外围镁铁-超镁铁质岩体的形成演化关系进行探讨,结果发现:这些岩体处于相同的构造环境,样品点整体为亚碱性拉斑玄武岩系列,随M g#值的增加,C aO,A l2O3,N a2O,K2O值具有连续减少的趋势,指示了它们存在连续的岩浆演化关系;稀土与微量元素分析,蛛网图整体具有右倾特征,龙首山岩带中段岩体有明显δEu负异常,东、西段岩体样品有δEu正异常或无异常,暗示中段岩体较外围岩体经历了更完全的分离结晶作用;结合前人对金川所做的S r-N d同位素等资料,证明金川岩体的岩浆源区为富集型地幔。
