Pidkova O. Genetic-Lithological Conditionality of Soil Cover Formation of Roztochchya.

Dissertation deals with morphogenetic peculiarities of the soils of Roztochchya depending on lithology of soil forming and laying rocks. Genetic-lithological conditionality of soil forming on different taxonomic levels has been substantiated. Lithocaten method has been applied for the first time in soil-geographical researches of the Western region of Ukraine. Phenomenon of lithogenic divergence of soil forming has been studied. A gross chemical composition of soils and soil forming rocks, mineralogical and petrographic composition of rocks have been determined and their edges have been described. Assessment of differentiation of soil profile has been carried out. Lithocatens nave been built in the limits of key plots.
