Tectonics of the western part of the Laptev sea shelf*
*The article is presented in two languages, Russian and English.

Main structural elements and disjunctive dislocation systems are revealed and traced from the results of integrated geophysical investigations (gravimetry, magnetometry and 2D seismic surveys) conducted in 2005 to 2010 within the Laptev Sea shelf. The breaks of the north-west strike identify the formation of the Laptev Sea Plate and its main structures: the Lena-Taimyr area of border uplifts, West-Laptevrift system and Novosibirsk system of grabens and horsts. The slips of the north-east strike dominate as transversal breaks of Cenozoic activation. Identification of the main disjunctive dislocation systems is the base for tectonic zonation and understanding of region evolution.

Key words: rifting, tectonic block, thrust, fault, slip, strike-slip, Laptev Sea Plate.
