| 摘 要： | 应用煤岩学方法，探讨了新疆伊犁盆地侏罗纪煤的煤岩特征及煤相划分，将煤相划分为９种类型即干燥森林沼泽相，潮湿森林沼泽相，草木混生型沼泽相或芦苇沼炭沼泽相。通过煤相分析，为伊犁盆地成煤环境的研究提供了佐证。

| Abstract: | Utilizing the coal petrographic method,the petrographic characteristics of Jurassic coal in Yili Basin are discussed,and nine coal facies are divided,i.e dry forest swamp facies (including two subfacies),wet forest swamp facies (three subfacies),mixed herbaceous and arboreous type swamp facies or reed bog facies (three subfacies )and open water peat swamp facies.By the coal facies analysis,an evidence is provided for the coal forming environment in Yilli Basin. |
