Abstract
The article reports morphotectonic and petrological characteristics of magmatic systems of Permo-Triassic traps in the sedimentary cover of the Siberian Craton, Taimyr, as well as in the crystalline basement of the Mesozoic cover of the West Siberian Plate and the Kara sedimentary basin based on the relief analysis, seismotomography data, magnetic and gravitational anomalies. Four development sectors of magma-permeable zones were distinguished along the perimeter of the craton of the Anabar Shield. The western sector is characterized by an extensive stretching area, on which the lava region of volcanic ridges junction of the Tunguska syncline formed. A striking feature of subaerial volcanism is the meridional petrochemical trend of increasing the silica of basic magmas in intrusive rocks of the Siberian Craton while the volumes of embedded melts are reduced.
