对深圳湾北岸新民钻孔岩心沉积物中铁、钒元素、矿物鉴定的伊利石以及生物指标贝类介壳揭示的环境特征资料进行了分析,研究初步表明,该钻孔岩心沉积物理深12.12~10.91m层段的杂色花斑粘土中存有晚更新世晚期至早全新世气候波动的记录。钒元素和伊利石分析也得到了相应的证实。所记录的短期降温和升温事件可能表明,在第四纪末次冰期-冰消期中,气候曾强烈波动,并逐渐由晚冰期向冰后期过渡。这对研究晚武木冰期最低海面时期以来,海面回升及晚更新世晚期/早全新世的古环境方气候影响提供有价值的资料。
The characteristics of iron, vanadium and illite identified from the core sediments of the borehole in Xinmin, north shore of Shenzhen Bay, and the environmental characteristics data revealed by the shellfish shell of the biological indicator were analyzed. Preliminary studies show that the sedimentary core has a physical depth of 12.12 ~ The variegated curvilinear clay in the 10.91 m layer contains records of the climatic fluctuations from the Late Pleistocene to the Early Holocene. Vanadium and illite analysis has also been confirmed. The recorded short-term cooling and warming events may indicate that during the last glacial-iceflooding of Quaternary, the climate had been strongly fluctuated and gradually shifted from late glacial to late glacial. This provides valuable data for studying the paleoenvironmental climate impact of Late Maywu ice age since the lowest sea level, sea level rise and Late Late Pleistocene / Early Holocene.
