For diatremes searching on Anabar crystalline shield classical scheme with measuring in both in frequency and time domain has been used. Using original algorithms in combination with robust statistical methods allow to significantly increase efficiency information quality of the field material and detect transient during switch on current pulse. The robust regression procedure was used for removing curves dependence from transmitter-receiving setup. Sediments covered diatreme was discovered in the vicinity of etalon object. The diatreme, which was verified more recently by a borehole, was non manifested in the resistivity map. Inversion of areal data of transients was performed within five-layers one dimensional induced polarization model and sensitivity is observed up to 1200 m depth.
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.
