The Loess Plateau lies in the North of China and is one of the most serious regions of soil erosion in the world. Severe loss of soil and water not only has its devastating effect on farming, forestry, stock-breeding and ecological environment of the area concerned, but also is the root of poverty for local people. The Loess Plateau has a long cultivation history, hence population growth, veget...

Lower Badenian deposits were newly exposed at Zaječí hora Hill (Brno city). Sedimentological and paleontological study of the succession recognised two facies associations. The lower one was formed by clastic known locally as “Brno sands”. upper is offshore clays “tegel”. Neogene beds covered Quaternary loess loam. interpreted progradation Gilbert-type delta foreset into relatively deep basin f...

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...

Fluvial strath terraces provide a record of river incision and the timing of climatic perturbations to the fluvial system. Dating depositional surfaces like terraces that are older than the range of C, however, is difficult. We employ a Ž . cosmogenic radionuclide CRN profile technique that addresses a major problem of CRN dating on such surfaces: nuclide inheritance. By measuring Be and Al pro...

Seismic compression is the accumulation of contractive volumetric strains in unsaturated soil from earthquake shaking. For Chinese loess, behavior seismic extremely significant and has been recognized historical earthquakes. As a main technical mean, dynamic triaxial apparatus employed to study compressibility loess for long time. However, simple shear superior modeling real stress condition un...

The intensity of agriculture has increased significantly during the past 30 years, resulting in increased detection of agricultural contaminants (nutrients, pesticides , salts, trace elements, and pathogens) in groundwater. Till, glaciolacustrine, and loess deposits of Quaterna-ry age compose the most common surficial deposits underlying agricultural areas in North America. Quaternary aquitards...
