UDC (552.3:551.21):551.76/.77(571.1) MESOZOIC-CENOZOIC TECTONIC MAGMATIC ACTIVATION AND LATE CRETACEOUS-PALEOGENIC ORE-LITHOGENESIS IN THE CIS-YENISEI ZONE OF THE WEST-SIBERIAN PLATE. PT 1
G. N. Cherkasov, N. V. Belyaev
Study of lithology of stratified systems of the plate complex (T) and cover (J1–Q) of the Cis-Yenisei zone of the West-Siberian Plate has revealed involvement of volcanism in their formation. Stages of tectonicmagmatic activation were reconstructed based on averaged thicknesses of the systems. The thesis suggested in the article was proven by data both on the cover and on the Jurassic-Cretaceous magmatism of the eastern and southeastern framing of the West-Siberian Plate. It was established that in the Cis-Yenisei zone of the West-Siberian Plate there were two stages of basaltoid and two stages of granitoid volcanism during the post-Mesozoic-Cenozoic time.
Key words: tectonic-magmatic activation, volcanism, hydrogoethite ore, bauxite, tuffaceous argillite, tuffaceous sandstone, genesis, ryolite, granite, lava, basalt. |
