В каменноугольное время их накопление происходило в условиях сноса обломочного материала, характеризующегося широким спектром возрастов. В перми преобладали источники сноса с узким диапазоном возрастов обломочного циркона. Согласно полученным результатам, образование кинырчадской свиты происходило в уфимское время (ранняя пермь). Древняя популяция обломочного циркона в нижне- и среднесилурийской уллулахранской свите свидетельствует о наличии в пределах питающей провинции блоков древней континентальной коры либо продуктов их размыва. Анализ полученных оценок изотопного возраста циркона из бечасынского метаморфического комплекса и обломочного циркона моласс зоны Передового хребта и Бечасынской зоны свидетельствует в пользу перигондванского происхождения комплексов, слагающих метаморфический фундамент этих зон и их формирования на окраине Гондваны в конце позднего рифея – венде. Альбский U-Pb возраст (102±1 млн лет, ±1σ), полученный по циркону из андезибазальтов долины р. Даут, ставит вопрос о возможности проявления мелового магматизма на Большом Кавказе.</p></abstract><trans-abstract xml:lang="en"><p>New data have been obtained on the U-Pb LA-ICP-MS age of detrital zircons from the Middle-Late Carboniferous and Early-Middle Permian molasses of the Greater Caucasus. The accumulation of molasses in the Carboniferous was associated with multiple-age clastic removal. The Permian was dominated by the source areas of detrital zircons with the narrow age range. According to the results obtained, the Kinyrchad formation dates back to the Ufimian (Early Permian). An ancient population of detrital zircons in the Early-Middle Silurian Ullu-Lakhran formation indicates the presence of blocks of ancient continental crust or products of erosion of the blocks within the feeding province. Analysis of the obtained isotopic data on the ages of zircons from the Bechasyn metamorphic complex and detrital zircons from the molasses of the Peredovoy Range zone and the Bechasyn zone testifies in favor of the peri-Gondwanan origin of the complexes making up the metamorphic basement of these zones and their formation on the Gondwana margin at the end of the Late Riphean – Vendian. U-Pb dating of zircons from the Albian-aged (102±1 Ma, ±1σ) andesibasalts of the Daut River valley raises the question of the probability of manifestation of the Cretaceous magmatic activity in the Greater Caucasus.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>U-Pb датирование</kwd><kwd>метод LA-ICP-MS</kwd><kwd>обломочный циркон</kwd><kwd>геохронология</kwd><kwd>Гондвана</kwd><kwd>меловой вулканизм</kwd><kwd>бечасынский метаморфический комплекс</kwd><kwd>Большой Кавказ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>U-Pb dating</kwd><kwd>LA-ICP-MS method</kwd><kwd>detrital zircon</kwd><kwd>geochronology</kwd><kwd>Gondwana</kwd><kwd>Cretaceous volcanic activity</kwd><kwd>Bechasyn metamorphic complex</kwd><kwd>Greater Caucasus</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено в рамках госзадания ИФЗ РАН.</funding-statement><funding-statement xml:lang="en">The study was carried out on the state assignment of the Schmidt Institute of Physics of the Earth RAS.</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">Baraboshkin E.Yu., 1999.
