摘要
本文以中天山西部新源阔尔库—拉斯台一带及伊什基克山一带石炭纪阿克沙克组沉积地层为研究对象,从野外产出状态、岩相学、岩石组合、沉积环境、生物化石分析、上下地层接触关系、构造环境等方面,对测区沉积地层作了比较系统的研究。通过近几年野外调查及综合研究,取得了如下认识:
     1.新源阿吾拉勒山一带和特克斯伊什基里克山一带早石炭世阿克沙克组的岩石组合,为一套浅海相碳酸盐岩和碎屑岩组合。
     2.于新源阿吾拉勒山一带和特克斯伊什基里克山一带早石炭世阿克沙克组地层内发现大量的化石组合,以珊瑚和腕足最为发育,其时代为早石炭世晚期,鉴别该地层的时代为早石炭世晚期。
     3.早石炭世阿克沙克组其下伏地层大哈拉军山组和上覆地层为伊什基里克组均为火山岩,因此该组是区分和识别上述两套火山岩的关键层,肯定了阿克沙克组与下伏地层大哈拉军山组和上覆地层为伊什基里克组接触关系均为不整合接触。
     4.依据岩石组合、生物化石、基本层序分析、与上下层的接触关系、上下层位形成环境,推知本组从总体演化看,开始时水体较浅,水动力存在较大变化,此时沉积环境为动荡的浅海环境,随着海水变深,水动力趋与单一,此时沉积环境为水动力不强的、静态的浅海环境,综合分析,本组为一套正常浅海相沉积。
     5.在该区阿吾拉勒山与伊什基里克山均见到因风暴作用形成的风暴岩,这一发现对该区古地理环境研究有重要意义。
     6.调查研究发现,新源阿吾拉勒山一带和特克斯伊什基里克山一带早石炭世阿克沙克组均可分为南、北两段,其南、北两段具有差异性,具弧前盆地和弧后盆地特色,但在整个伊宁盆地自东而西具有较好的相似性可对比性。
     7.在前人研究的基础上,结合近几年的野外调查与室内资料的收集整理,对本区早石炭世阿克沙克组地层进行了重新划分与对比,前人将新源阿吾拉勒山一带石炭世的大哈拉军山组、阿克沙克组和伊什基里克组统规划为石炭世的大哈拉军山组,现将其解体出来;特克斯伊什基里克山一带早石炭世阿克沙克组划分不统一,将之前划为早石炭世阿克沙克组的晚石炭世东图津河组和晚石炭世科古琴山组,经调研对比分析,从早石炭世阿克沙克组划分出来,厘定为下石炭统东图津河组和科古琴山组;将伊什基里克山萨尔不顺一带原划为大哈拉军山组的早石炭世阿克沙克组分离出,厘定为早石炭世阿克沙克组;特克斯县吉勒苏布拉克一带的XX—XX′号实测剖面阿克沙克组经调研分析对比,仍划归为早石炭世阿克沙克组,结束了以前对该区早石炭世地层认识混乱的现象。
The author studies the sedimentary stratum of Lower carboniferous Akeshake formation in Awulale Belt of Xinyuan and Yishijike mountain of Tekesi in the west of the Middle Tianshan, involving its the field occurrence, petrography, rock association, sedimentary environment, organic fossil analysis , the Contact relations of its overlying and underlying stratum Construction Environment et al.,the character of sedimentary stratum is more systemical researched Through the several years of field survey and general research, the main results in study are following:
     1. The rock association of Lower carboniferous Akeshake formation in Awulale Belt of Xinyuan and Yishijike mountain of Tekesi is a series of Neritic association of carbonate rock and clastic rock.
     2.We have been found in the sedimentary stratum of Lower carboniferous Akeshake formation in Awulale Belt of Xinyuan and Yishijike mountain of Tekesi,especially the coral and the brachia.,and they are belongs to Advanced of the Lower carboniferous,the times of this sedimentary has been identificated as Advanced of the Lower carboniferous.
     3.The sedimentary stratum of Lower carboniferous Akeshake formation in Awulale Belt of Xinyuan and Yishijike mountain of Tekes both its underlying stratum of Dahalajun mountain and overlying stratum of Yishijilike are volcanic rock,so this sedimentary is the key of distinguish and identitication of the two series of volcanic rock above. The Akeshake formation contanct with both its underlying stratum of Dahalajun mountain and overlying stratum of Yishijilike in unconformable relation,local contanctions were infected with late Construction perform in chase.
     4. According to rock association,organic fossil,basics succession of strata analysis, the Contact relations of its overlying and underlying stratum,forming environment of its overlying and underlying stratum,througr the whole evolution this stratum was guessed that,the water was Shallow and the hydropower perform variably,thus sedimentary environment is The turbulence of shallow sea environment,with the deeper of the sea, the hydropower tend to Single,thus sedimentary environment is the weak hydropower、stable of shallow sea environment. through the general research,this formation is a series of normal shallow sea sedimentary.
     5.Storm rock formed in the storm were found both in Awulale mountain and Yishijike mountain,this foundation has an important means to this area's study of the Palaeogeography environment.
     6.The analytical research result of the sedimentary stratum of Lower carboniferous Akeshake formation in Awulale Belt of Xinyuan and Yishijike mountain of Tekes,both can be devided into north-south two section,which have dfference and the characteristic of foearc basin and back-arc basin,but it has well comparability and comparatively contrast in all Yining basin from east to west.
     7. In the basic of the former investigation, integrates fieldwork of the near years and data collect coordinate in the room, we newly confirm and block the Carboniferous Formation Akeshake formation in Awulale belt Xinyuan,which the former man generally compartmentalize the Early Carboniferous Formation Dahalajunshan formation for the Early Carboniferous Formation Dahalajunshan formation、Akeshake formation and Yishijilike formation,now we disaggregate their. The Early Carboniferous Formation compartmentalized is contravention in Yishijilike belt Tekesi,the Late Carboniferous Dongtujinhe formation and Keguqinshan formation were compartmentalized the Carboniferous Akeshake formation,now we compartmentaliz Lower Carboniferous Dongtujinhe formation and Keguqinshan formation for the Early Carboniferous Formation compartmentalized to investigate disquisition,it compartmentalizes the Early Carboniferous Akeshake formation for former compartmentalized the Early Carboniferous Dahalajunshan formation in Saerbushun belt Yishijilike,the Akeshake formation XX-XX' size profile in Jilebushubulake belt Tekesi still compartmentalizes the Early Carboniferous Akeshake formation to investigate disquisition,so it finishs the former confusion cognition phenomena in Yishijilike belt Tekesi.
