摘要
As Quaternary sediments, aggradational red earth and Xiashu Loess are frequently seen in the subtropical zone in China. Grain-size, quartz surface characteristics, magnetic susceptibility, and REE of red earth are tested and compared with Xiashu Loess. The results show that, generally, the physical and chemical characteristics of red earth and Xiashu Loess are similar to each other, indicating aeolian characteristics.
