The material on the western section of the Glukhivetsky deposit of eluvial kaolins, which is located in the Koziatyn district of the Vinnytsia region, near the village of Glukhiv and is part of the Glukhivetsko-Turbivsky kaolin region.
 The causal relationships of different petrotypes of bedrock with the thickness, material composition and zonation of the weathering crust and, as a consequence, with the structural and lithological structure of the eluvial kaolin deposit and its qualitative indicators are revealed.
 Based on the coordinates and description of wells, the relief of the top and of the bottom surface of the kaolinite-hydromicaceous zone of the weathering crust and of the layer of eluvial kaolins, as well as the lateral change in their average thickness, were studied. Correlations between of the top and of the bottom surface and thickness of the kaolinite-hydromicaceous zone and eluvial kaolins have been studied. Based on the results of well testing and chemical analysis of kaolins, the lateral distribution of the average contents of iron and titanium oxides and the average content of the whiteness index, as well as their correlations, was studied.
