Bstract.The article presents the results of medium-scale geological mapping of the Momo-Selennyakh depression. New data on the deep structure, ore and oil-and-gas bearing capacity of the depression were established. Reliable and presumptive signs of oil and gas content were revealed. The geologic structure of the depression, including its location in the Kolyma-Omolon superterrane bordering the Verkhoyansk fold system, was discussed. The Momo-Selennyakh depression is located within the Kolyma-Omolon superterrane, which borders the Verkhoyansk fold system. The depression was formed as a result of crustal stretching in the Late Pliocene - Early Pleistocene. It is composed of sand and gravel deposits of Miocene and Pliocene age overlain by Pleistocene glacial formations. The Selennyakh and Syuryuktyakh depressions are part of the Momo-Selennyakh depression, which is located within the Kolyma-Omolon superterrane. The Selennyakh depression has a gentle shape and is composed of Upper Jurassic sedimentary-volcanogenic formations. The basement of the depression is disrupted by faults along which the blocks moved.The Syuryuktyakh depression has a more complex structure and is composed of loose sediments of Paleogene-Neogene and Quaternary age. The basement of the depression is composed of Upper Silurian and Devonian carbonate sediments and Upper Jurassic sedimentary-volcanogenic formations. The depression was formed in the zone of the large Ulakhan fault. The results of hydrogeochemical sampling indicate the presence of hidden mineralized crushing zones associated with the Ulakhan fault. These zones have elevated contents of cadmium, boron, copper, zinc, lead, molybdenum and other metals. The presence of bituminous shales, increased content of naphthenic acids, iodine, bromine and uorine in waters, as well as the presence of oily patches and griffons with gas emission indicate possible oil-bearing capacity of the area.

Periodic 24-hour variations in the intensity of galactic cosmic rays, continuously observed by ground-based detectors, are called solar diurnal variations. The nature of these variations lies in the existence in the interplanetary medium of an anisotropic spatial distribution of galactic cosmic rays, which arises during the interaction of these particles with the heliosphere. It is believed that the physical factors responsible for the observed anisotropy of galactic cosmic rays are the processes of convection, diffusion and their drift. The combination of these factors determines the main parameters of solar diurnal variations, such as amplitude, phase and energy spectrum. To study the energy spectrum of solar-diurnal variations, we used measurement data from muon telescopes of the Yakutsk Cosmic Ray Spectrograph after A.I. Kuzmin and Nagoya stations (Japan). The research approach is based on the idea of the crossed telescope method, originally designed to take into account the temperature effect. Due to the difference in the receiving characteristics of the crossed northern and southern directions of the above muon telescopes, the intensity variations recorded by them are sensitive to changes in the energy spectrum of solar-diurnal variations. This property was used to assess the dynamics of the energy spectrum of solar-diurnal variations for 22-25 cycles of solar activity. Analysis of the data obtained showed that in the last minimum of solar activity in 2018-2021. An anomalously early phase of solar-diurnal variations was observed. To study this phenomenon, we simulated the ratio and phase difference of a pair of northern and southern crossed directions for both muon telescopes for different types and values of the energy spectrum of solar-diurnal variations. A comparison of model calculations and observational data has made it possible to establish that during periods of minimum solar activity in the positive polarity of the general magnetic field of the Sun, a significant softening of the energy spectrum of solar-diurnal variations is observed. The reasons for the discovered phenomenon are discussed.
