Geochemical characteristics of acidic dike swarm from the eastern segment of the Ertix tectonic belt, Altai orogeny and its geological implications.

  • 野外地质调查发现在阿尔泰南缘额尔齐斯构造带东段、额尔齐斯活动断裂与富蕴-锡泊渡断裂之间发育了一套未变形的酸性岩墙群.岩墙群侵位于海西期片麻岩化花岗岩和上石炭统深变质的额尔齐斯组岩层中,薄片鉴定和岩石地球化学分析确定为具有细晶结构的流纹斑岩.岩石的SiO2含量为70.9%~75.38%,K2O+Na2O含量为7.55%~8.99%;大部分样品Na2O>K2O,里特曼指数值为1.8~2.5之间,Al2O3=12.80%~14.53%,A/CNK=0.9~1.1,NK/A=0.7~0.9,具有准铝质-弱过铝质、低镁、高钾钠、低钙和锶、高(Fe)mol/(Mg)mol特点,具A型花岗岩类特点,属于亚碱性脉岩.岩石轻稀土富集,大离子亲石元素相对富集,具有明显的中等负铕异常,壳源特征明显.锆石U-Pb二次粒子微探针测年显示岩墙群形成于277~286Ma.推断岩墙是阿尔泰海西期造山运动结束后,在拉张构造环境下的地壳局部熔融产物.
