Abstract—The relationships between the main tectonic features in the north of central and western Siberia are
analyzed on the basis of the available geologic and geophysical data. The chain of troughs and syneclises,
including the Yenisei–Khatanga Foredeep, the Lena–Anabar Trough, and the Ust-Yenisei and Yamal–Gydan
syneclises are bounded in the north and south by systems of swells of approximately the same size and age. It
is suggested that these swells, having appeared simultaneously with the troughs, were eroded subsequently and
then buried beneath the Mesozoic–Cenozoic sediments.
