| 摘 要： | 对汉江上游郧县—郧西段一级阶地物质上堆积的黄土状覆盖层的剖面构型、粒度、矿物组合、元素分布、微形态及形成时代进行了研究,并与渭河谷地全新世黄土—古土壤序列对比.结果表明,这些“黄土状覆盖层”是晚更新世以来沙尘暴在区内连续堆积的结果,具有TS-L0-S0-Lt-L1-AD剖面构型；这些风积物在不同时期受到了不同程度的成壤...

| Abstract: | Loess-like sediments over the first level river terraces of the Upper Hanjiang River Valley between Yunxian and Yunxi were surveyed in detail and then sampled systematically. Pedogenic modification characteristics and the structure of soil profiles were observed in the field survey.Particle-size distribution,mineral assemblage,major elements and trace elements,magnetic susceptibility,CaCO 3 ,micromorphology and OSL age were analyzed in laboratory and compared with Holocene loess-paleosol sequences in the We... |
