Abstract

On the basis of field investigations along the upper Hangjiang River valley, a typical loess-soil section was found at the Tuojiawan (TJW). Magnetic susceptibility and particle-size distribution were measured in laboratory. OSL ages were measured by using the quartz single aliquot regenerative-dose protocol. The OSL results show that the optical ages of these samples ranged in 55.11-13.57 ka BP, showing a good relation with the depth in the TJW profile. It indicated that the profile was formed by loess weathering and accumulation. The content of clay, clay/coarse silt ratio, magnetic susceptibility in 228-260 cm and 294-370 cm were higher than those in Malan loess. The weathering intensity of this depth was obviously higher than that of Malan loess, close to the palaeosol (S0), belongs to the weak palaeosol (L1-S1 and L1-S2). The age range of L1-S1 and L1-S2 was 27.26-21.59 ka BP. The change of the indexes showed the climate and pedogenic environment changed since Pleistocene. It indicated there was a short time of warm and wet in the cold and arid glacial period (27.5-21.5 ka BP), and the southeast monsoon gradually intensified during the early Holocene periods with the strongest monsoon in the mid-Holocene.
