| 摘 要： | 博格达东段石炭系火山岩发育,通过1:5万区域地质调查工作,将该区划分为3个组,即下石炭统七角井组、上石炭统下部柳树沟组及上石炭统中上部祁家沟组.文中对3组地层中火山岩地质及岩石学、主量元素、稀土元素、微量元素地球化学特征研究表明,下石炭统七角井组、上石炭统下部柳树沟组是以拉斑玄武岩为主的双峰式火山岩建造,上石炭统中上部祁家沟组是小范围火山岩-碎屑岩-碳酸盐岩建造,各组火山岩均为钙碱性拉斑系列,岩浆源是幔源岩浆与地壳物质混合物,形成环境为板内裂谷环境. |
| 关 键 词： | 博格达东段 双峰式火山岩建造 拉斑玄武系列 板内裂谷 |

| Abstract: | Carboniferous volcanics rocks are widely distributed in the eastern area of Bageda Mountain with the lower level of research.According to 1:50000 region geological surveys,we are individed Carboniferous rock into three formations,namely the Lower Carboniferous Qijiaojing formation,the Upper Carboniferous Liushugou formation,The middle-upper part of the Upper Carboniferous Qijiagou formation.In this article,the volcanic rock geology and petrology,major element,REE,trace elements geochemistry characteristics ... |
| Keywords: | The eastern of Bogda Mountain Bimodal volcanic construction Series of tholeiite Intraplate rift |
