    塔里木板块北缘活动陆缘型侵入岩带的岩石学与地球化学

    Petrology and geochemistry of an active continental margin intrusive rock belt onthe northern margin of the Tarim plate

    • 摘要: 在塔里木板块北缘,断续出露一条侵入岩带,总长度800多公里。岩石组合是橄榄辉长岩-辉长岩-辉长闪长岩-闪长岩-石英闪长岩-花岗岩。各种类型岩石的化学组成显示了清晰的钙碱性岩浆演化趋势。稀土元素配分曲线均为轻稀土富集型,而且,重稀土元素配分曲线相对平坦。Sr、K、Rb、Ba、Th等大离子亲石元素强烈富集,而Ta、Nb、Zr、Hf、Ti等高场强元素显著贫化。这些岩石学与地球化学特征均证明,该侵入岩带形成于活动大陆边缘。
