Аннотация


Установлен 40Ar/39Ar методом возраст санидина, составляющий 369.7 ± 4.0 млн лет, из высококалиевых трахитовых обломков флюидо-эксплозивной брекчии трубчатого тела, прорывающего базальтовый покров раннедевонского канино-тиманского комплекса. Трахитвый магматизм является завершающим этапом формирования щелочной магматической провинции калиевой специализации на Среднем Тимане.
