Loess in China [Paperback]

The distribution, deposition, composition and texture of loess in China is studied. Based on on-the-spot investigations, Loess and the Environment supplies information on: the loess-paleosol time sequence, loess fabric, and geological events derived from studying biological relics. Proceeding from the loess environmental system, the climatic fluctuation sequence of different scales has been reconstructed, and the whole process of eolian loess accumulation and its relationship with modern silt dust, water and soil conservation, engineering geology, agricultural soil as well as local diseases are discussed.The distribution, deposition, composition and texture of loess in China is studied.
