      <abstract xml:lang="ru">
        <p>Наблюдения в горных выработках и пещерах позволяют выявлять особенности строения и развития разрывных структур в приповерхностных условиях на различных этапах геологической истории территорий. На основе существующей модели формирования карстовой системы Кунгурской Ледяной пещеры рассмотрены преобразования зон деформаций, возникших в толще переслаивающихся сульфатных и карбонатных пород в условиях платформы. Морфологические особенности вертикальных структур – органных труб, развитых в пределах одной из пачек, сложенной гипсами и ангидритами, определяются этапами эволюции дизъюнктивных нарушений, пронизывающих всю толщу пород, слагающих массив Ледяной горы. Сосредоточенная инфильтрация поверхностных вод, формирование единого канала, в сводах которого со временем происходят разуплотнение пород и обвалы из перекрывающих отложений, в настоящее время считаются инициаторами формирования труб. В дальнейшем на поверхности образуется провал, увеличивающий количество поступающей воды в карстующийся массив. Однако размеры обломков в осыпях, несоизмеримые с устьями труб, округлые своды отдельных труб, фрагменты фидерных каналов, характерных для артезианских условий циркуляции подземных вод, отпрепарированные обломки пород из перекрывающих отложений, особенности строения стенок определяют первичность формирования труб по отношению к гротам и галереям пещеры. Пластические свойства гипсовых отложений и процессы их гидратации определяют вторичные изменения стенок труб вплоть до полного заполнения пустотного пространства с образованием вторичных целиков с последующим возобновлением формирования вертикальных каналов, значительно меньших в диаметре и образующихся уже под действием коррозии инфильтрационными водами.</p>

        <p>Observations in mining tunnels and caves allow to identify composition and development specifics of fault structures under subsurface conditions at various stages of geological history. Basing on the existing formation model of Kungur Ice Cave karst system, author examines the transformations of deformation zones, occurring in the mass of interlaid sulfate and carbonate rocks under platform conditions. Morphologic specifics of vertical structures ­– organ pipes, developed within one of the gypsum-anhydrite units, are defined by evolution stages of disjunctive faults, penetrating the entire rock mass of the Ice Cave. Point infiltration of surface waters and formation of a single channel, where rock softening and taluses from overlapping deposits gradually occur, are currently considered to be the initiators of pipe formation. At a later stage a sink forms on the surface, increasing the amount of water coming to the karsting mass. However, the size of debris in the talus, incommensurate with the pipe head, rounded arches of separate pipes, fragments of feeder channels, characteristic for artesian conditions of underground water circulation, faceted rock debris from overlapping deposits, specifics of wall structure all define the priority of pipe formation over grottos and cave galleries. Plastic properties of gypsum sediments and processes of their hydration define secondary modifications of pipe walls up to complete filling of the voids and formation of secondary pillars with subsequent renewed formation of vertical channels – significantly smaller in diameter and formed by infiltration waters when subject to corrosion.</p>
