Comparative Characteristic of Aeolian Loessial Soils Samples

Comparative characteristic of aeolian loessial soils samples,whose sections are from North China (Beijing)and pre-Caucasia(Bujennovck).As far as we know,there are many questions can be researched in the area of loess.For the sake of solving engineering and ecogeological problems,we have to begin with knowing loess’ composition,structure, physical,physicochemical,physicomechanical properties and first of all—the property of sedimenttation.
