Геохимия, морфология и структура циркона подтверждает его магматическое происхождение. Продолжительность интрузивного магматизма около 20 млн лет. Изотопная Lu-Hf система циркона свидетельствует о деплетированном мантийном источнике (εHf(T) = +8…+15) и двух группах модельных возрастов THf(DM): 0,57–0,59 и 0,26–0,29 млрд лет. В качестве источника траппового магматизма предполагается плавление рифейской деплетированной мантии Палеоазиатского океана под воздействием пермского плюма.</p></abstract><trans-abstract xml:lang="en"><p>Following zircon ages (U-Pb method, SHRIMP II) from four trap intrusions was obtained (Ma): 248 ± 2 for Vanga, 241 ± 2 for Yokche, 235 ± 1 for Degali, 230 ± 3 for Perelomnaya. Zircon geochemistry, morphology and structure confirms its magmatic origin. The duration of intrusive trap magmatism is about 20 Myr. The Lu-Hf isotope system of zircon testifies to depleted mantle source (εHf(T) = +8…+15) and two groups of THf(DM) model ages: Riphean (0.57–0.59 Ga) and Permian (0.26–0.29 Ga). Melting of the Riphean depleted mantle of the Paleo-Asian Ocean under the influence of the Permian plume is supposed to be a source of trap magmatism.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Сибирская платформа</kwd><kwd>траппы</kwd><kwd>циркон</kwd><kwd>U-Pb возраст SHRIMP II</kwd><kwd>Lu-Hf изотопная система</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Siberian Platform</kwd><kwd>trap</kwd><kwd>zircon</kwd><kwd>U-Pb age</kwd><kwd>SHRIMP II</kwd><kwd>Lu-Hf isotope system</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при составлении Госгеолкарты РФ м-ба 1 : 1 000 000/3 листа Q-46 – Тутончана.
