长江三角洲全新世海平面重建研究综述

摘要

This study summarizes Holocene sea-level research at China and abroad and describes various relative sea-level indicators and scientiifc questions. There are clear differences in relative sea level in different areas of the world related to factors such as glacio-hydro isostasy, local differential tectonic subsidence, and sediment compaction and re-deposition. Basal peat, diatom and foraminifer-based sea-level transfer functions, marine sediments, palaeohuman ruins, total organic carbon/total nitrogen, δ13C, total organic carbon, total solids, and authengenic iron sulifde are impactful indicators, and al have their advantages and disadvantages in reconstructing Holocene sea level.%通过综述国内外全新世海平面重建研究进展,总结了全新世海平面重建的各种指标和海平面重建存在的科学问题,认为冰川—水均衡作用、区域差异性构造沉降、沉积物压实和侵蚀再沉积作用是各地区全新世海平面差异性存在的主要原因;对长江三角洲各海平面重建指标进行了有效性分析,得出基底泥炭、硅藻、有孔虫转换函数,海相地层、古人类遗址、TOC/TN和δ13C、TOC/TS和自生铁硫化物是重建海平面的有效指标,并对每个指标的优缺点及重建时需要考虑的问题进行了阐述.
