| 摘 要： | 通过对红井子地区石炭纪人山岩岩石学、岩石化学、稀土元素、微量元素等特征分析；认为该区石炭纪火山岩具岛弧火山岩和裂谷火山岩两种不同属性，其形成构造环境也存在明显差异。该区火山岩分别形成于三个不同的构造环境，即准噶尔岛弧带、博格达裂谷带及喀尔力克岛弧带。

| Abstract: | The analysis of lithology, petrochemistry, rare earth elements and trace elements of the Carboniferous volcanics reveals that the volcanics share the characteristics of both island-arc type ed rift-valleytype. An obvious differnce exists in terms of tectonic environments. The volcanics were formed in three dif-ferent tectonic setting, including Junggar island-arc zone, Bogda rift-valley zone aam Karlik island-arc zone. |
