Phosphorite and glauconite-bearing sediments as an agricultural raw materials (on the example of objects in the central and western regions of Ukraine)

Report NDR: 253 p., 45 pic., 21 tabl., 2 annex., 225 sources. The object of research was phosphorite- and glauconite-bearing rock formations of the central and western regions of Ukraine, minerals that are used as fertilizers, as a means to improve the agrochemical properties of soils or as mineral additives to feed. The aim of the work was to develop the mineral resource base of agro-ore (phosphorite- and glauconite-bearing formations) through following objectives: creating a database of the distribution of promising formations; studies of the features of the material composition of the useful components of these formations and the recommendations development regarding the prospects of their usage and regarding search criteria for the raw materials localization. The obtained research results are presented in the report eight chapters and annexes containing information on the created GIS-integrated database of the glauconite- and phosphorite-bearing deposits distribution. The territory zoning was developed according to the patterns of glauconite- and phosphorite-bearing rocks distribution and the most complete list of off-balance deposits and glauconite manifestations was compiled. For the first time, a list of complex and potentially complex deposits and manifestations has been identified, one of the useful components of which is or may be glauconite. The nanotextural and nanostructural features of phosphorites various types of Ukraine were studied using precision research methods. The transformations of phosphate- bearing matter in lithogenesis are analyzed. The data obtained on the material composition of phosphorites and their ultramicrotextures made it possible to propose a phosphorites processing technology improvement, with involvement of modern biotechnological methods, which significantly will reduce the cost of mineral. The use of glauconite-bearing rocks for the restoration of the landscapes of Pollissia destroyed during the extraction of amber is proposed
