| 摘 要： | 对宣城第四纪红土剖面的研究表明，全氧化铁含量能够较好地指示中国南方第四纪气候的波动。与北方黄土古土壤序列相比，宣城剖面的全氧化铁明显较高，指示了南方地区更强的风化成壤作用。

| Abstract: | As a large environmental section in the Eastern Hemisphere, PEPII covers the laterization areas in the Southern part of the Country. It studies mainly different paleoclimatic records, specially continental records in the section. Various laterite successions are an important carrier of continental paleoenvironmental records in China. The study of Quaternary laterization profile in Xuancheng, Anhui Province shows that the paleoclimatic fluctuation in South China during Quaternary can be clearly described by the total iron oxide. Compared with the succession of loesspaleosol series in North China, the content of total iron oxide of Xuancheng profile is much higher. It refers that the sediments from Southern area of China have undergone a stronger weathering since it deposited. Furthermore, the curve of total iron oxide in Xuancheng profile coincides with the oxygen isotope of V28 238 core. |
