| Реферат: | eng: The age of the major igneous complexes in the western part of the Selenga-Stanovoy superterrane has been estimated by 40Ar/39Ar dating: trachyandesite-basalts of the Kuitun (Chichatka) complex-259.4±6.2Ma; gabbro of the Tukuringra complex-156.3±4.8Ma; granites and pegmatites of the Tukuringra complex-153.1±3.8, 154.0±4.4, 156.8±4.0, and 151.2±3.2Ma; granodiorites, granites, and leucogranites of the Amudzhikan complex-131.7±2.4, 134.5±2.8, and 131.6±4.2Ma; and lamprophyre dikes-125.2±2.4 and 125.2±3.4Ma. Two stages of hydrothermal ore formation process have been recognized: 132-131 and ~125Ma. It is shown that the deposit formation and superposed processes follow the general regularities of the Late Mesozoic evolution of the Pacific Asia margin. © 2014.
