| Summary: | Petrogeochemical and isotope-geochronological data are of paramount importance for refining the geologic correlation between weakly exposed magmatites of the Kolyvan'-Tomsk folded zone and Kuznetsk basin. We report data on dike and dike-sill basite complexes of shallow-depth genesis. According to the 40Ar/39Ar age estimates, basites in the Kuznetsk and Gorlovka basins are older than dikes free of xenogenous matter in the Tomsk magmatic area(248.95 ± 1.81- 246.2 ± 1.4, 259.1 ± 3.4, and 241.6 ± 2.7-238.0 ± 5.2 Ma, respectively) and are close in petrogeochemistry to basites of the Tashara complex in the Novosibirsk magmatic area. These data suggest the synchronous occurrence of magmatic events related to the Permo-Triassic plume activity within the West Siberian Plate, Siberian Platform, and their southern folded framing В фонде НТБ ТПУ отсутствует |
