Geochemical groundwater peculiarities of Paleogene sediments in S-E Western Siberia artesian basin

The geochemical peculiarities of groundwater in Paleogene deposits in southeastern part of Western Siberia artesian basin are considered in the paper. Landscape, climate, geostructural and hydrogeological conditions define the water composition and quality peculiarities in this region. It has been established that ion-saline composition, mineralization and water quality changes arre governed by the horizontal zonal distribution. Groundwater of taiga landscapes generally is in equilibrium with kaolinite and quartz, mainly involving Ca- and Mg-montmorillonite, illite, carbonate minerals, sometimes barite. Groundwater in woodland grass and grassland, together with previously mentioned minerals, is usually in equilibrium with barite, colestine, and particularly, fluorite and gypsum. As a result, all relevant elements are removed from the groundwater and their accumulation level is restricted

Взаимосвязь органических и неорганических веществ при формировании мочевых камней

Macro- and microscopic structural features of human urolyths have been studied to reveal the relation between organic and inorganic components and the role of the latter in the process of urolyth formation and growth. The combined study of the shape, color, surface, mineral and organic composition, and internal structure and zoning of 788 urolyths has been performed. Crystallomorphological, polarization-optical, X-ray-diffraction, electron-microscopic, chemical, neutron-activation, and computer technologies of study of the urolyth structure have been used. It has been found that macroscopic characteristics of uroluths (color, shape, surface, and size) did not reflect the chemical composition of urolyths. In the structure of abundance of urolyths in Tomskand the Tomsk Region, oxalates (58%) and urolyths of complex mineral composition (29%)  prevail. It has been found that an urolyth is an organomineral aggregate having the internal structure formed by a rhythm of alternation of organic and inorganic layers and the character of arrangement of individual mineral crystals, and the internal structure is independent of the chemical composition of the urolyth and  uniform in urolyths of different chemical composition. The most part of urolyths has a mixed (44%) or druzy (35%) type of crystal arrangement and the  combined (45%) or grainy (31%) rhythm of alternation of organic and inorganic components.Исследованы макро- и микроскопические структурные особенности мочевых камней человека с выявлением взаимосвязи органической и неорганической составляющих и роли последней в процессе формирования и роста камня. Выполнено комплексное исследование формы, цвета, характера поверхности, минерального и органического составов, а также внутренней структуры и зональности 788 мочевых камней. Использованы кристалломорфологические, поляризационно-оптические, рентгеноструктурные, электронно-микроскопические, химические, нейтронно-активационные, а также компьютерные технологии изучения строения уролитов. Установлено, что макроскопические признаки камня (цвет, форма, характер поверхности и размеры) не отражают его химического состава. В структуре распределения мочевых камней в г. Томске и Томской области преобладают оксалаты (58%) и камни сложного минерального состава (29%). Выявлено, что мочевой камень является органоминеральным агрегатом, имеющим внутреннюю структуру, сформированную ритмом чередования слоев веществ органического и неорганического строения и характером расположения отдельных кристаллов минералов, при этом внутренняя структура не зависит от химического состава камня и однотипна у камней разного химического состава. Большая часть мочевых камней имеет смешанный (44%) или друзовидный (35%) тип расположения кристаллов и комбинированный (45%) или зернистый (31%) ритм чередования органических и неорганических составляющих
