GEOCHEMICAL CHARACTERISTICS OF THE YOUHULUGOU BASALTS IN THE SUTURE ZONE OF THE NORTH QILIAN MOUNTAIN

  • 摘要: 对油葫芦沟蛇绿岩中玄武岩进行了地球化学研究, 以探讨其形成环境。油葫芦沟蛇绿岩中玄武岩的主量和微量元素具有低钾富钠的特征, 属低钾(拉斑)系列。玄武岩的球粒陨石标准化稀土元素分配模式图表现为近平坦型, 轻重稀土富集不明显, 属于亏损地幔(N型)。大离子亲石元素(LILE)Rb、K和Sr出现负异常, 高场强元素(HFSE)Nb、Ta、Hf、Zr无负异常, 表现出大洋中脊幔源岩浆作用的特征。构造环境判别图显示, 油葫芦沟玄武岩属于典型的亏损型大洋中脊玄武岩(MORB)。研究结果表明油葫芦沟蛇绿岩中玄武岩为北祁连洋洋壳的组成部分, 北祁连洋在晚元古代—晚寒武世为典型的大洋中脊环境。
