Реферат: | eng: Results of integrated Ar-40/Ar-39, Rb-Sr, and Sm-Nd geochronological studies of the Lukinda dunite-troctolite-gabbro-anorthosite massif in the northeast of the Selenga-Stanovoi superterrane, Central Asian Fold Belt, are presented. It is shown that this massif is much younger than formerly thought: 249 +/- 14 to 251 +/- 15 Ma vs. Paleoproterozoic. This date of magmatism corresponds to one of the stages of the formation of the Selenga-Vitim belt, which ranks among the largest Phanerozoic volcanoplutonic belts in Central Asia. (C) 2018, V.S.
