| 摘 要： | 分布于博格达山西南缘的桃西沟群,是一套典型的山间磨拉石相构造—沉积组合,时代为早二叠世,它是博格达火山弧演化为褶皱带的造山作用晚期阶段,由边缘岛海环境突发性地快速转化为陆相构造—沉积环境的产物。

| Abstract: | The Lower Permian Tiaoxigou Group on the southwestern slope ofthe Bogda Mountain(E.Tianshan) is typically a series oftectono depositionalassociations ofinter montane depression type molasse facies.It might be the result of the sudden evolution from a marginal island sea tectono depositionalenvironment to a terrestrialdepositional environment during the later orogenic phase from epicontinentalvolcanic arc to fold belt happened in the Bogda area. |
