新疆伊犁盆地含煤地层构造演化与聚煤地质特征

Tectonic Evolution of the Coal-bearing Strata and Coal Accumulating Geological Characteristics of Yili Basin,Xinjiang

为研究伊犁盆地含煤地层地质特征,综合利用露头、岩芯资料,以层序地层学、沉积学等理论为指导,分析了伊犁盆地构造特征、沉积演化特征,讨论了伊犁盆地含煤岩系层序地层格架、富煤带的空间展布规律。在此基础上,对伊犁盆地聚煤地质特征及找煤方向进行了探讨,对于区内煤炭资源勘探部署及开发利用有一定的参考价值。

In order to study the geological characteristics of the coal-bearing strata in Yili basin,based on the outcrop and core data,taken the theory of sequence stratigraphy and sedimentology as the guidance,the tectonic characteristics and sedimentary evolution characteristics of Yili basin are analyzed,the stratigraphic framework of the coal-bearing rock series and the spatial distribution regularities of coalrich zone of Yili basin are discussed in depth. Based on the above analysis results,the coal accumulating geological characteristics and coal prospecting direction of Yili basin are analyzed. The above analysis results related to the tectonic evolution of coal-bearing strata and coal accumulating geological characteristics of Yili basin can provide some reference for the exploration and development of coal resources,besides that,it also has some reference for the development and utilization of the coal resources in Yili basin.
