| 摘 要： | 通过对江汉平原北部蔡垱西剖面沉积物粒度、地球化学元素、孢粉等相关数据的综合分析,揭示了该地区约1250年以来环境演变历史。通过沉积物的野外观察、粒度数据分析及剖面所处地貌部位的综合分析认为,该剖面沉积物主要为汉江等周围水系洪水带来的泥沙泛滥至低洼平原区,并以近乎停滞的低缓流速沉积而成,所以沉积物以细粒的黏土质粉砂为主,...

| Abstract: | The Caidangxi profile is in the north of Jianghan Plain,Hubei Province,China.Synthetic analysis of grain size,chemical elements and pollen of sedimentary samples from Caidangxi profile reveal the paleo-environmental changes since 1250 AD of the area.The sediments of the profile dominantly consist of clay silts.The sedimentary characteristics,such as grain size and the sorting coefficient,together with the analysis geomorphic position on which the deposition occurred,may indicate that the sediments were depo... |
