渤海湾北岸MT04孔粒度特征及沉积环境演化
|
摘要
利用渤海湾北岸MT04钻孔野外地质钻探资料和室内颗粒分析成果,用实验室实验所得的粒度参数和粒度概率曲线、频率曲线,结合沉积结构和构造特征,对沉积环境演化进行了系统的分析.自晚更新世以来,该段地层自下而上划分7个沉积单元,这些沉积单元构成河漫滩—河漫湖、滨湖相—冲积扇相、浅湖相—湖相三角洲—浅海相3个沉积旋回,反映出研究区湖泊接受河流沉积物,逐渐被填充的过程.
Based on the field geological drilling data about MT04 borehole and the result of indoor particle analysis, and combined with the sedimentary structure and structural characteristics, this research systematically analyzes the evolution of sedimentary environment by using the particle-size parameter and probability curves, and frequency curves obtained from laboratory experiment. Since the late Pleistocene, this stratum section has been divided into seven sedimentary units from bottom to top which constitute 3 deposit cycles: floodplain facies-fluvial lacustrine facies, lake facies-alluvial fan facies,shallow lake facies-lake delta facies-shallow sea facies, reflecting the process in which the fluvial deposit had accumulated and then filled the lake in the study area.
