CHEMICAL AND MINERALOGICAL INDEX OF PODZOLISATION OF THE GRANITE REGOLITH SOILS

摘要

Tatra Mts soils formed on the granitoide weathering and weathering granitoide covers was studied. These soils are shallow and skeletal, very typical for the mountain regions. Chemical properties and diagnostic criteria for the spodic horizon occurringin these soils place these soils among Podzols. During the podzolisation process i.e. during the biological-geochemical weathering process new layers of clay minerals like smectite, vermiculite and kaolinite or mixed layered minerals containing hydratedinterlayer are formed.
