| Abstract: | Four seismic horizons (L1, L2, L3, and L4) were recognized in the Laptev Sea Basin. The seismic complexes that lie between the horizons were found and dated (125-55.8, 55.8-33.9, 33.9-5.3, and 5.3-0Ma). A Paleozoic carbonate plate exists in the southwestern Laptev Sea Basin below the L1 horizon. Rifting in the Laptev Sea Basin began shortly after the Verkhoyansk orogeny ended at about 125 Ma BP. The evolution of the Laptev Sea Basin is correlated with that of the Eurasian Basin and the climatic history of the region. |
