Structural Evidence of Recent Activity of the Khatanga-Lomonosov Fault Zone in the Laptev Sea

摘要

New structural data obtained by a geophysical survey during Cruise 69 of the R/V Akademik Mstislav Keldysh in 2017 indicate that the Khatanga-Lomonosov fault zone is presently active and propagating in Khatanga Bay. The orientation of conjugated extension and compression structures points to the sinistral displacement along this zone. The results confirm the concept that this zone represents a transform fault separating Gakkel Ridge from the rift system of the Laptev Sea shelf.
