Abstract
General information on the geological structure and ore-bearing capacity of the Likarivske and Andriivske deposits, which are located in the southwestern part of the Korsun-Novomyrhorod pluton within the Novomyrhorod massif (South-Western part), is provided. The productive deposits of the Likarivske and Andriivske deposits are represented by the weathering crust formation and the continental alluvial sand-kaolin formation of the Lower Cretaceous (Aptian-Lower Albian). On the basis of the coordinates, description and results of testing wells, a target database was created. On the basis of this database, cartographic constructions were carried out. The structural (relief of the bottom and of the top surfaces of ore-bearing deposits and their thickness) and material (lithological composition of productive deposits; lateral distribution of the average content of ilmenite, zircon, rutile and apatite in productive deposits) parameters of different ages and different genetic formations of the Likarivske and Andriivske deposits were studied. The direction and strength of correlations between ilmenite, rutile, zircon, and apatite in the weathered crust and continental sediments (sands and redeposited kaolins) of the Lower Cretaceous were studied. It was established that within the limits of the Likarivske and Andriivske deposits, during the geological development of the territory, a zircon-apatite-ilmenite ore-bearing system of different time and different genetics was formed, which is represented by a spatial-paragenetic series: crystalline rocks of the foundation; weathering crusts of crystalline rocks of the foundation; fluvial formations formed due to erosion and redeposition of eluvium; fluvial formations that were formed due to erosion and redeposition of eluvium and Mesozoic-Cenozoic placers of different ages. The results of the research are an information base for supporting mining operations within the studied deposits.
