| 摘 要： | 却勒塔格一带下石炭统小热泉子组为一套滨浅海相火山岩夹少量正常沉积碎屑岩建造,上被上石炭统底格尔组不整合覆盖,火山岩组合以玄武岩-安山岩-英安岩-流纹岩最为发育.火山岩岩石化学、地球化学特征表明,小热泉子组火山岩主要属钙碱性系列,一般以富钠为特征,稀土元素和微量元素分布型式与火山岛弧钙碱性火山岩分布型式基本吻合. |
| 关 键 词： | 东天山 小热泉子组 火山岩 岛弧 |

| Abstract: | The volcanic rock of early carboniferous Xiaorequanzi formation is mostly distributed in the western of Jueluotage mountains of Xinjiang.it's belong to estuarine deposition face,intercalary strata is normal clastic sediments,and unconformable cover with late carboniferous Diger formation,the volcanic rock mainly included basalt,andesite,dacite, rhyolite.The volcanic rock petrochemical characteristics indicate that the Xiaorequanzi formation volcanic rock belong to calc alkali rock series,and high Na+,REE an... |
