Study shows that environment evolution and eustatic change of Holocene in this area may be divided into 6 stages:① early stage of early Holocene, 9 100~10 900 aBP,when sea level was low and this area was an oxidizing environment or oxidizing-reducing transition environment;② late stage of early Holocene, 8 000~9 100 aBP, sea-level rising,...

研究表明，本区全新世环境演化分为6个阶段：①早全新世早期，10900~9100aBP，海平面较低，尚未淹没本区，为近岸氧化环境或氧化—还原过渡环境；②早全新世晚期，9100~8000aBP，海水上涨，本区时淹时退，为浅海或潮坪环境，生物钻孔发育；③中全新世主体，8000~4150aBP，海平面快速上升，完全淹没，Fe2+/Fe3+介于0.7395~1.9123之间，为全新世中最高段，表明还原程度强、全球气候变暖；④中全新世后期，4150~2850aBP，海水有所下降，仍为浅海环境，Fe2+/Fe3+较高，多在1.0以上；⑤晚全新世，2850~1310aBP，海平面进一步下降，本区时常暴露，其中2150~1310aBP以还原环境为主，为潮下带，2150~2850aBP以氧化—还原过渡环境为主，为潮间带；⑥1855AD以来，海平面基本稳定，稍有上升，为现代黄河三角洲沉积时期。本区全新世至少存在5期冷热交替的旋回性气候变化。
