Abstract:

对北阿尔金蛇绿混杂岩带中红柳泉剖面的枕状玄武岩进行了岩石地球化学研究,主元素具有高钛高钠、低铝低钾的特点。其中SiO??2?含量为43.34%~52.55%,Na??2?O含量为3.97%~7.36%,K??2?O含量为0.27%~0.94%。TiO??2?含量为2.13%~5.49%,Al??2?O??3?含量为9.02%~13.77%,显示出细碧岩(Spilite)的地球化学特征。微量元素配分模式类似于洋岛或海山玄武岩(OIB/Seamount),不同于洋中脊玄武岩(MORB)。??87?Sr/??86?Sr比值为?0.7043?~0.7052,??143?Nd/??144?Nd比值为0.51253~0.51265,ε??Nd?(448Ma)为2.19~3.88,玄武岩浆主要来自于上涌的含有富集组分的软流圈地幔。综合考虑剖面上出现的沉积岩石组合,推测玄武岩形成于弧后盆地的海山环境。在阿尔金走滑断裂形成以前,北阿尔金与北祁连构成一个统一的弧后盆地系统,是原特提斯洋在中国境内的最北部边界,这对认识青藏高原和中国西部大地构造格局的演化具有重要意义。
