Lack of correlation between paleoprecipitation and magnetic susceptibility of Chinese loess/paleosol sequences
We have conducted a detailed mineral magnetic study of loess unit 8 (L8) and paleosol unit 8 (S8) from three localities (Jingbian, Yichuan, and Duanjiapo) along a N-S transect in the Chinese loess plateau. As expected, the lowfield magnetic susceptibility (χ) has higher values in S8 and lower values in L8. Similarly, superparamagnetic particle concentrations increase in S8 with increasingly hum...
متن کاملExperimental Validation of Retardation of Tritium Migration in the Chinese Loess Media
Retardation of tritium migration in the Chinese loess media was studied through column experiments by comparison of the migration velocity with other three “non-adsorptive” tracers of Br, Tc, and I. Results showed that the transport peak of Br was 1.25 times earlier than that of tritium when the tracers were simultaneously injected into the column, and the migration of Tc was even 1.60 times fa...
متن کاملRadiocarbon and Stable Carbon Isotope Analyses of Land Snails from the Chinese Loess Plateau: Environmental and Chronological Implications
Paired radiocarbon and stable carbon analyses have been carried out on aragonite shells and organic soft bodies of snails from the Chinese Loess Plateau in order to explore the possibility of using these kinds of samples as environmental and chronological indicators. Results show that the soft bodies exhibit 14C concentrations similar to those of plant leaves, indicating that carbon in the soft...
متن کاملThe Loess Plateau
The Loess Plateau (34°–40°N, 103°–114°E) is situated in the northern part of Central China (Fig. 2.1). It borders on North China Plain in the east, adjoins Qinghai-Tibet Plateau in the west, stands in the north of Qinling Mountains, and neighbors Inner Mongolia Plateau in the north. The Loess Plateau is a part of the dryland region in northwest China, with its altitude in the range of 800–3000 ...
متن کاملActual daily evapotranspiration estimated from MERIS and AATSR data over the Chinese Loess Plateau
The Chinese Loess Plateau is located in the north of China and has a significant impact on the climate and ecosystem evolvement over the East Asian continent. Estimates of evapotranspiration (ET) at a regional scale are in crucial need for climate studies, weather forecasts, hydrological surveys, ecological monitoring and water resource management. In this research, the ET of the Chinese Loess ...
