| 摘 要： | 舒兰第三系含煤盆地是受依－伊地堑控制形成的半地堑式线型盆地，充填有古新世－中新世地层，其地层构造格架，沉积特征均具典型的陆相断陷盆地特点。盆地沉积经历了初始断陷－裂陷扩大－萎缩等８个构造沉积演化阶段。含煤地层主要为舒兰组，具有湖前和湖后两个聚煤期。聚煤环境主要为河流洪积平原的三角洲，扇前湿地环境。

| Abstract: | Tertiary coal basin in Shulan is controlled by Yilan-Yitong graben,deposited Paleocene-Miocene strata, whose strata teconic framework and sedimentary are characteristiced by contineutal fault basin. The basin occured in the early extensionthe middle large extension-the late contraction. It is divided into eight tectonic and sedimentary stages.The main coal-bearing strata is Shulan form,the coal-accumulation period including pre-lake facies and paul-lake facies. Coal accumulation environments are mainly the delta of stream-flood plain and marsh. |
