| 摘 要： | 八道湾组为伊犁盆地内主要含煤地层之一,本文通过钻井、测井、古生物、野外露头剖面等资料的分析识别出侏罗系中下统主要发育扇三角洲、三角洲、湖泊、沼泽等主要相类型,八道湾组为1套在潮湿、温暖气候条件下形成的以湖泊、三角洲一沼泽相为主的含煤碎屑岩建造。八道湾早期,全区分布有伊宁、尼勒克、巩留3个沉积中心,具有填平补齐的特征;八道湾晚期,沉积范围逐步扩大,沼泽大面积分布,为伊犁盆地重要的成煤期。这对于指导研究区煤炭的勘探具有重要意义。 |
| 关 键 词： | 伊犁盆地 八道湾组 成煤环境 沉积 |

| Abstract: | Badaowan formation is the main coal-bearing formation in Yili Basin.Fan delta,delta,lake,delta,swamp facies can be identified by applying the drilling,logging,palaeontology and outcrop data.The Badaowan Formation,a coal-bearing clastic rock formation,is a suite of lake-delta-swamp faces sediment in the humid warm weather conditions.Three depocenters have been distinguished for the evaporates: Yining,Nileke and Gongliu in Yili Basin with filling characteristics in early period of Badaowan Formation.The late ... |
