Рассматриваются геохимические особенности пород из разрезов Дальний Тюлькас и Мечетлино, расположенных в южной части Предуральского прогиба и предлагаемых в качестве международных эталонов для глобальной корреляции нижних границ артинского и кунгурского ярусов. Материалы и методы. Содержание породообразующих окислов и некоторых других компонентов изучено по 15 и 20 образцам карбонатных, глинистых и песчаных пород соответственно в разрезах Дальний Тюлькас и Мечетлино. Определение химического состава пород выполнено с использованием волнодисперсионного рентгенофлуоресцентного спектрометра S8 Tiger (Bruker, Германия). Результаты. Дана литологическая характеристика разрезов, приведено содержание породообразующих компонентов в аргиллитах и известняках пограничных (сакмарско-артинского и артинскокунгурского) интервалов. Показано, что аргиллиты разных стратиграфических уровней практически идентичны по средним содержаниям основных компонентов, тогда как известняки имеют некоторые различия. Проанализированы корреляционные связи породообразующих оксидов и сделаны выводы о минеральном составе пород. С использованием петрохимических модулей и диаграмм установлено, что глинистые породы в рассматриваемых разрезах имеют главным образом гидрослюдистый состав. На основании анализа индексов химического выветривания показано, что климат в приуральскую эпоху был преимущественно аридным. Тектоническая обстановка, в которой формировались породы, слагающие источники сноса, предположительно соответствовала активной и пассивной окраинам континентов. Выводы. Основные литохимические характеристики пород двух рассматриваемых разрезов в целом несколько различаются, однако границы стратиграфических подразделений в пределах каждого из них по литохимическим параметрам практически не выделяются, что может свидетельствовать в пользу непрерывности осадконакопления на границах веков приуральской эпохи в данном регионе. Условия осадконакопления и характер размываемых пород в области сноса оставались относительно постоянными. Это является положительным моментом при рассмотрении разрезов в качестве эталонных объектов – “золотых гвоздей”.</p></abstract><trans-abstract xml:lang="en"><p>Object. Geochemical features of rocks from the Dal’ny Tulkas and Mechetlino sections located in the southern part of the West Urals foredeep are considered and are offered as International Standards for the global correlation (GSSP) of the lower boundaries of the Artinskian and Kungurian stages. Materials and methods. The content of rock-forming oxides and other components were studied for 15 and 20 samples of carbonate, clay and sandy rocks respectively in the sections of Dalnii Tyulkas and Mechetlino. The determination of the chemical composition of rocks was performed using a wave-dispersive X-ray fluorescence spectrometer S8 Tiger (Bruker, Germany). Results. The lithological characteristics of the sections, the content of oxides in mudstones and limestones of the boundary Sakmarian-Artinskian and of the boundary ArtinskianKungurian are taken. Mudstones of different stage are almost identical in average contents of the main components, whereas limestones have some differences. Correlative connections of oxides are analyzed and conclusions about mineral composition of rocks are made. Using the petrochemical modules and diagrams, it was established that the clay rocks in considered sections have mainly a hydromica composition. Based on the analysis of the indices of chemical weathering CIA, it is shown that the climate in the Cisuralian Epoch was predominantly arid. The tectonic environment of forming demolition sources, presumably corresponded to the active and passive margins of the continents. Conclusions. The main lithochemical characteristics of the rocks of the two sections under consideration are somewhat different, however, the boundaries of the stratigraphic subdivisions of each of them are virtually indistinguishable by lithochemical parameters, which may indicate the benefit of the continuity of sedimentation at the borders of centuries of the Cisuralian Epoch in this region. The conditions of sedimentation and the nature of eroded rocks in the area of demolition remained relatively constant. This is a positive point when looking the sections as International Standards for the global correlation (GSSP) reference objects – “golden nails”. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>пермь</kwd><kwd>приуральский отдел</kwd><kwd>геохимия</kwd><kwd>литология</kwd><kwd>петрохимические модули</kwd><kwd>эталонные разрезы</kwd><kwd>Дальний Тюлькас</kwd><kwd>Мечетлино</kwd><kwd>Предуральский прогиб</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Permian</kwd><kwd>Cisuralian</kwd><kwd>geochemistry</kwd><kwd>lithology</kwd><kwd>petrochemical modules</kwd><kwd>reference sections</kwd><kwd>Dal’nyTulkas</kwd><kwd>Mechetlino</kwd><kwd>West-Uralian foredeep</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке РФФИ (грант № 16-05-00306а) и за счет средств субсидий, выделенных Казанскому (Приволжскому) федеральному университету в рамках государственной поддержки в целях повышения его конкурентоспособности среди ведущих мировых научнообразовательных центров и для выполнения проектной части государственного задания в сфере научной деятельности.</funding-statement><funding-statement xml:lang="en">The work was supported by the Russian Foundation for Basic Research (Grant No. 16-05-00306a) and at the expense of subsidies allocated to the Kazan (Volga Region) Federal University as part of state support in order to increase its competitiveness among the world’s leading scientific and educational centers tasks in the field of scientific activity.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Головенок В.К.
