Abstract
Geological and geophysical studies of northeastern Yakutia and the coast of the Laptev Sea to determine seismotectonic patterns of this poorly studied region show that within the plate boundary running from Greenland to Alaska, a rare situation is observed when oceanic rifts, extending as a transition zone into the system of Cenozoic basins, crossed the entire eastern Yakutia from the coast of the Laptev Sea to the Sea of Okhotsk and developed until the Upper Pleistocene as the Mominsky rift system. In modern times, the Momin basin system is developing in the mode of transpression, which is associated with the movement of the Eurasian and North American plates towards each other. This is due to the location of the rotation pole of these plates, shifted from the coast of the Sea of Okhotsk towards the Laptev Sea.
