A new scheme of tectonic zoning of the lithosphere upper part of the Pre-Caspian depression

Morphotectonic and petrological characteristics of Permo-Triassic traps of Siberia

“…The problems of PTTS genesis were solved based on the analysis of satellite images and geological maps. The PTTS manifestation areas, the geology of which is illustrated in Figure 1, demonstrate the coincidence of morphological structures of the WSP basement overlapped by sedimentary rocks with the basement structures in the WSP and Kara Sea petroleum basins (Figure 2) [48][49][50][51][52][53]. Morphological structures characteristics of the PTTS volcanic formations do not significantly differ in areas covered by Meso-Cenozoic sediments (Figure 1), which is confirmed by data on the thickness of the sedimentary rocks in the petroleum basin (Figure 3) [48].…”
