Description

Attempt was made for the determination of duration of all abyssal system formation in the central part of the Kola peninsula. System of isotope methods inclosing Rb-Sr-isochronic dating, 40Ar/39Ar-age analysis of rocks as well as U-Th-Pb-dating is applied. Formation of the Khibiny-Lovozero-Kurga volcano-plutonic system is proposed to have a multiphase character. Summary scheme of the order of events is performed

Abstract (Russian)

Предпринята попытка определения длительности формирования всей магматической системы в центральной части Кольского полуострова. Применен комплекс изотопных методов, включающий Rb-Sr-изохронное датирование, определение 40Ar/39Ar-возраста пород, а также U-Th-Pb-датирование. Предполагается, что формирование вулкано-плутонической системы Хибины-Ловозеро-Курга имело многофазный характер. Представлена суммарная схема последовательности событий
