Mineralogical Composition of the Clay Fraction in Alluvial Soils of Eastern Georgia

摘要

The mineralogical composition of the clay fractions separated from alluvial soils in the valleys of the Kura and lori rivets—the main rivers of eastern Georgia—has been studied. It is shown that alluvial soils are very diverse with respect to theirphysicochemical properties, particle-size distribution, and mineralogy, In comparison with zonal automorphic soils, the alluvial soils have a lower content of organic matter and a coarser texture. The diversity of mineral associations in them is larger than that in the zonal soils.
