HOLOCENE STRATIGRAPHY AND PALEOENVIRONMENTAL EVOLUTION OF THE NORTHERN YELLOW RIVER DELTA
-
摘要: 根据2007年在黄河三角洲北部布设的一口31 m浅钻和9个探槽的沉积学观测、微体古生物鉴定等资料,通过对黄河三角洲北部ZK3孔的地层分析,将其全新世地层自上而下划分为现代黄河三角洲沉积、浅海沉积、潮坪沉积和河流沉积4层,将现代黄河三角洲沉积进一步划分为4个亚层,并解释了古环境演变。结合黄河频繁改道的详细历史记录,运用历史地理学和沉积地质学综合分析的方法对现代黄河三角洲沉积部分进行了精确的年代划分,其他层位也进行了年代推测,并与黄河三角洲北部其他钻孔进行了对比分析。Abstract: A 31-meter-sediment core, obtained from the northern Yellow River Delta in 2007, was analyzed for sedimentary characteristics and benthic foraminiferal assemblages in order to document the environmental history of the region. Nine trench profiles were dug for better understanding the upper 1.5~2.0 m of the deposits. There are four layers of deposits in the area, namely, the modern Yellow River delta deposit, the shallow sea deposit, the tidal-flat deposit and the fluvial deposit. Based on the fact, the paleoenvironmental evolution of the region was discussed. Precise chronological framework of the modern Yellow River delta (MYRD) was built upon the detailed records of paleo-geography and sedimentary geology left by the shifting of Yellow River course, while the time framework before the MYRD was deduced by comparing the core with the others nearby from available literatures.
