Geological and geophysical structural features of Predverkhoyansky foreland basin and neighbouring areas: data from new along-river 2D CDP seismic survey line and reinterpretation of legacy data

The paper presents geological model of the Lensky branch of Predverkhoyansky Foreland Basin and zone of its joint with the Vilyuisky hemisyneclise. The latest seismic data integrated with unconventional processing of gravity and magnetic fields allowed updating architecture of the eastern margin of the Anabarsky Syneclise, Predverkhoyansky Foreland Basin, and eastern part of the Vilyuisky, as well as the Kyutingdinsky graben and the Kitchansky anticline. Geoseismic section along the Lena River profile was presented for the first time, which crosses the zone of Anabarsky Anteclise, Predverkhoyansky Foreland Basin, and Vilyuisky hemisyneclise joint
