Abstract

The red earth in southern China has been generally considered potential paleoenvironmental record. In order to reveal the paleoenvironmental implications of the red clay profile in southern China and its relationship with chemical index of alteration (CIA), the authors measured magnetic susceptibility and chemical elements of two hundred and sixty-three samples collected from Huangjin (HJ) ,Shahe (SH), Tiancun (TC), Gaoxing (GX), Songmu (SM) in Xianggan area. Some conclusions have been reached: (1) The average magnetic susceptibility of the vermiculated red clay layer is higher than that of homogeneous red clay layer and red soil layer in Gannan region. The low frequency magnetic rate of granite clay in Gannan region is higher than that of granite clay in Hengyang region. The distribution ranges of the low frequency magnetic susceptibility of red clay sections vary from 12.1×10 ^-8 m ³/kg to 463.91×10 ^-8 m ³/kg;(2)There is still preferable relationship between the low frequency magnetic susceptibility and chemical index of alteration (CIA) in Hengyang region. The high magnetic susceptibility values correspond to the high CIA values, indicating a warm and humid envirenment; the low magnetic susceptibility values correspond to the low CIA values, indicating a cold and dry envirenment.(3)The low-frequency magnetic susceptibility curves are regionally different in frequency and amplitude, the low frequency magnetic susceptibility of the red clay section shows a consistent downward trend, which reveals the change trend of palaeoclimate from warm-wet to warm-dry during the red clay deposition period.

Key words： Xianggan area red earth section low frequency magnetic susceptibility chemical index of alteration(CIA)
