GEOCHEMISTRY AND GENESIS OF BASIC-INTERMEDIATE VOLCANIC ROCKS FROM KALADAWAN, EAST ALTUN TAGH MOUNTAINS

  • 摘要: 新疆阿尔金山东段喀腊大湾地区位于北东向阿尔金走滑断裂北侧与东西向阿尔金北缘断裂所夹持的区域,区内发育一套火山沉积岩系。对其中中基性火山岩进行较为系统的岩石地球化学研究,结果显示为LREE微弱富集型和部分平坦型两种稀土配分曲线型式,为岛弧型火山岩; 微量元素的Zr/Nb、Nb/Ta以及Zr/Hf比值分析等地球化学特征表明本区经受了地壳物质的混染作用,火山岩的La-La/Sm投影显示为部分熔融和分离结晶共同作用产生的; Hf-Tu-Ta和TFeO-Na2O+K2O-Mg的构造环境投图显示本区火山岩主要为拉斑系列的火山弧玄武岩,推测本区早古生代为板块俯冲带上盘的岛弧环境,玄武岩类以幔源为主。
