Structure of the Khatanga–Lomonosov Fracture Zone according to Seismic Data

Resumo

Based on the results of geophysical data interpretation, the structural features of the Khatanga–Lomonosov fracture zone (KhLZ), adapted to the junction zone between the Laptev Sea continental margin and structures of the Eurasian spreading basin and the Lomonosov Ridge, are considered. The KhLZ reflection in anomalous geophysical fields and in wave seismic patterns observed in the sections is shown on the example of separate links, and also the character of its kinematic interrelations with heterogeneous tectonic elements is illustrated. The tectonic nature and the role played by this fault zone in the geodynamic evolution of the region are substantiated.
