| 摘 要： | 选取江苏省南通市黄泥山150cm黄土堆积剖面为研究对象,进行环境磁学及粒度分析,探讨黄泥山黄土堆积的成因。研究发现该堆积物属黏土质粉砂,其粒径较镇江下蜀黄土及北方红黏土、黄土为细。南通黄泥山黄土堆积与镇江大港下蜀黄土的磁性特征具明显的相似性。结合粒度、环境磁学数据推测南通黄泥山黄土堆积与大港下蜀黄土相同,为风成堆积物,堆积物磁性参数的高、低变化反映了暖湿、干冷沉积环境的交替。黄泥山黄土较镇江大港下蜀黄土剖面具有较低的细颗粒亚铁磁性矿物含量和较高的退磁参数S-100比值,指示南通黄土与大港黄土相比,总体上经历了较弱的成壤作用。

| Abstract: | Huangnishan hill is located in the southern area of Nantong City,Jiangsu Province. In this paper,we studied magnetic and granulometric characteristics of loess deposits from the Huangnishan hill and the origin of loess. The sediments are dominated by silty clay,and finer than those of both the Xiashu loess in Zhenjiang and the loess in the Chinese Loess Plateau. Huangnishan loess is similar to Xiashu loess in magnetic property,implying that the Huangnishan loess is the same as the Xiashu loess in Zhenjiang ... |
