Байкал вблизи некоторых населенных пунктов и в п. Хужир, для определения ряда его характеристик, позволяющих сделать вывод о возможности применения песка для нужд пищевой промышленности и пищевой инженерии. Для определения гранулометрического состава песка был использован метод ситового анализа, предполагающий разделение сыпучей смеси на отдельные фракции посредством вибрации с использованием комплекта сит, определение массы каждой фракции и процентного соотношения фракций в исследуемом веществе. Рентгеноструктурный анализ проб песка, произведенный при помощи дифрактометра Bruker D8 Advance, позволил определить фазовый состав вещества и выделить в образцах преобладающие структуры. По результатам проведенного рентгенографического анализа определена кристаллическая структура составляющих минералов. Установлено, что минералогический состав в наибольшей степени представлен кварцем - в разных пробах его доля составляла от 40 до 60 %. Альбит и анортоклаз в данных пробах присутствуют в количестве от 15 до 30 %. Незначительную долю в каждой пробе представляют минералы диккит и индиалит - менее 5 %. В песке, взятом на исследование в п. Ангасолка, около 9 % составляет антофиллит. Результаты ситового анализа после соответствующей обработки показали следующее. Большинство проб по зерновому составу достаточно однородны, в каждой пробе имеется преобладающая фракция. Исключение представляет проба песка из г. Слюдянки, в которой наблюдается большой разброс размеров частиц. Песок отобранных проб может быть классифицирован как озерный или озерно-ледниковый. Кристаллохимический состав достаточно разнообразен. Установлено, что основной составляющей песков являются кварц и полевой шпат, присутствует небольшое количество других минералов. Результаты определения гранулометрического состава свидетельствуют о том, что для песка с побережья вблизи г. Слюдянки характерен большой разброс размеров частиц, в остальных пробах сыпучего материала имеется преобладающая фракция. Для целевого использования в пищевой отрасли наиболее подходящим является песок г. Байкальска, поскольку в пробе преобладает фракция среднего размера.</p></abstract><trans-abstract xml:lang="en"><p>A study of the characteristics of the sand samples from the southwest shore of Lake Baikal has been carried out, with the purpose to find out the possibility of using the sand for the needs of the food industry. To determine the granulometric composition of the sand, a sieve analysis method has been applied, i.e. the separation of the granular mixture fractions using a set of sieves, with the further determination of the mass of each fraction and their percentage in the test substance. The sieving has been carried out by means of vibration. The X-ray analysis of the sand samples has used a Bruker D8 Advance diffractometer. The method allows determining the parameters of the crystal lattices, analyzing the phase composition of the test substance, and identifying the prevailing structures in the sample. Based on the x-ray analysis results, the crystal structure of the mineral components has been determined. The study has shown the following mineralogical composition of the sand. The prevailing mineral is quartz, its content varying from 40 to 60 percent; the content of albite and anorthoclase is 15 to 30 percent, and a small fraction is represented by dikkit and indialit (less than 5 percent). In the sand samples taken in the settlement of Angasolka, about 9 percent is represented by antophyllite. The processed results of the sieve analysis show the following. Most samples have been found to be quite homogeneous in terms of their grain composition, each sample having a predominant fraction, with the exception of the sample taken in the town of Slyudyanka, in which the particle size varies significantly. The studied sand samples can be classified as lacustrine or lake-glacial, their crystal-chemical composition being quite diverse. The study shows that the main components in the sand composition are quartz and feldspar, with a small content of other minerals being present. The granulometric analysis results show that the sand samples taken at the lakeshore in the vicinity of Slyudyanka are characterized by a large dispersion of the particle sizes, while other samples of the bulk material contain a predominant fraction. The sand from the Baikalsk area is most suitable for use in the food industry as it contains middle size fractions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>песок</kwd><kwd>минеральное сырье</kwd><kwd>минералогический состав</kwd><kwd>генезис</kwd><kwd>гранулометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sand</kwd><kwd>mineral raw materials</kwd><kwd>mineralogical composition</kwd><kwd>genesis</kwd><kwd>granulometry</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Морозов Н.М., Боровских И.В., Галеев А.Ф.
