通过沉积相分析,确定了鹤岗盆地为陆相断陷湖盆沉积的冲积扇—辨状河—曲流湖—湖泊三角洲—湖泊沉积体系。通过连井剖面着重分析了沉积相垂向及平面的分布特征,对鹤岗盆地成煤时期沉积环境有了初步的了解。
By sedimentary facies analysis, the sedimentary system of alluvial fan-discernment river-meandering lake-lake delta-lake in the Hegang Basin is determined. Based on the analysis of the vertical and horizontal distribution of sedimentary facies, the sedimentary environment of Hegang Basin during coal formation was preliminarily understood.
