The paper presents the results of a systematic study of the physical, chemical, and structural geometrical characteristics of Hotynetsky aluminosilicate deposits. Chemical and phase composition of the mineral was specified with the help of the data obtained by energy dispersive x-ray spectroscopy, x-ray diffraction, and IR spectrometry. It is shown that the composition of the mineral is dominated by aluminosilicates with a regular crystal structure: dioctahedral montmorillonite with ions of alkaline earth metals in interpackage positions with the general formula of (Ca,Mg)(Al,Fe,MgO2(OH)2[(Si,Al)4O10]∙nН2O; clinoptilolite K3Ca2(Si29Al7)O72∙nH2O; modifications of silica (SiO2) cristobalite and quartz, and illite (K0.75(H3O)0.25)Al2(Si3Al)O10((H2O)0.75(OH)0.25)2 Based on the data for the study of the morphology of mineral surface by atomic force and electron microscopy we can conclude that the studied mineral has a composite flocculent crystal-grained globular structure. Its surface is presented in the form of aggregates of flake and blade shape with a size of 1-10 µm, tightly adjacent to each other and forming a single frame with numerous macropores. If you decrease the scale length of the scan globular structure of individual sections of the surface with fragments of crystalline inclusions appears. The diameter of the globules varies in the range of ~ 40 nm ÷ 200 nm; the pores formed between the globules have a width of 4-6 nm to 13-15 nm (micropores), and the diameter of the pores formed due to the defective structure of the mineral ranges is 30 nm to 80-100 nm (mesopores). According to the sorption of methylene blue porous structure of the aluminosilicate under formation has a specific surface area of ~ 16.7 m2/g, the concentration of basic centres on the surface of mineral is 52 µmol/g, and the concentration of acid sites is 30 µmol/g.  The obtained data are interesting for further study of its sorption and catalytic properties and for creating new functional materials.
