| 摘 要： | 西天山—伊宁地区以独特的结构特征和关键的大地构造部位,历来成为中外地质学家所关注、研究的重要地区,而那拉提构造带及邻区又在西天山—伊宁地区占有举足轻重的地位。由于客观条件的制约,那拉提构造带及西天山造山带在基础地质的许多方面存在不少问题,直接影响到对天山造山带和伊犁盆地的正确认识。笔者根据近十年来在那拉提带及邻区进行10个1∶5万区调填图和收集到的其它资料,对该区几个重要层位的时代、大哈拉军山火山岩系的形成背景、蛇绿岩和蓝闪片岩的产出特征以及该区的结构、构造单元划分和发展演化的动力学机制进行了讨论,其中的许多认识和看法将对该区的进一步研究产生推动作用。 |

| Abstract: | The area of West Tianshan-Yining,with its special geology and key tectonic characteristics,has been a fascinated place for domestic and foreign geologists.Nalaqi structure belt and its neighbor region are very important to the geology study in the area of West Tianshan-Yining.There are many questions about several aspects of the basic geology in Nalaqi structure belt and West Tianshan Orogen,of which directly influence understanding to the geology of Tianshan orogen and Yining Basin.In this paper,on the basis of the document got in last ten years from the regional geology surveying and mapping with the scale of 1:50000 as well as other geology materials,the author systematic discusses the geology problems,including the time of the main strata,the background of the formation of Dahala Junshan volcanic rock,occurrence of the ophiolite and glaucophane schist,the division of the structure and tectonic elements and its development evolution,in the Nalaqi structure belt and its neighbor region.Knownledg and ideas of this paper are vey useful and would be promote further study to the geology in the area. |
| Keywords: | Nalaqi structure belt the time of the main strata the ophiolite and glaucophane schist the background of the formation of Dahala Junshan volcanic rock characteristics of the texture Xinjiang China |
