Abstract
Analysis of seismic cross sections in the Laptev Sea showed that a sedimentary basin is developed in the western part of the water area, the thickness of platform deposits in which is 15–20 km. A complex interpretation of geological and geophysical materials on the continental margin of the Siberian platform and the Laptev Sea water area was carried out, seismogeological models of sedimentary complexes on the continent and in the sea were compared, and gravity and magnetic anomalies were analyzed. The research results showed that the western part of the Laptev Sea, in geological terms, is a northern continuation of the Siberian platform. The oil and gas potential of this part of the water area will be associated with the Upper Proterozoic-Middle Paleozoic carbonate deposits and Permian-Mesozoic terrigenous sedimentary complexes.

Summary
Шельф; сейсмический разрез; волновые и потенциальные поля; сейсмокомплекс; осадочный чехол; фундамент; Море Лаптевых; Сибирская платформа; Хатангский залив. Анализ сейсмических разрезов по морю Лаптевых показал, что в западной части акватории развит осадочный бассейн, мощность платформенных отложений в котором составляет 15–20 км.
