The article reveals the activities of the Zolotinka geocryological station in South Yakutia, one of the BAM expeditions of the Institute of Permafrost, USSR Academy of Sciences. Relevance. The article is dedicated to the 95th anniversary of the birth of Maria Gavrilova, a climatologist, permafrost scientist, famous in Russian and world science, Doctor of Geographical Sciences, professor, Honored Scientist of the Russian Federation and the Republic of Sakha (Yakutia), academician of the Academy of Sciences of the Republic of Sakha (Yakutia), the Russian Academy of Natural Sciences [1]. The BAM expeditions of the Institute of Permafrost were united by a common research topic “Prediction of the evolution of the cryolithozone in the development of the territory adjacent to the BAM railway” to predict the state of geocryological conditions and make practical recommendations for the construction of engineering structures in settlements, stations and roads in the Maly BAM zone [2]. In di erent natural conditions, landscapes of the foothills of the Stanovoi Ridge of South Yakutia (valleys, watersheds, as well as on the slopes of di erent exposures), special permafrost conditions are formed associated with the patterns of heat exchange of the upper layers of the earth’s crust - the earth’s surface - the atmosphere [2]. To identify permafrost, microclimatic and thermal balance conditions in the midlands of South Yakutia, on the territory of the village of Iengra of the Neryungrinsky City Council, on September 1, 1975, the Zolotinka geocryological station was organized under the leadership of Dr. Gavrilova. The year-round station conducted three full cycles of microclimatic and thermal balance studies from 1975-1978. A retrospective approach to the topic of the BAM expedition organized by the Institute of Permafrost made it possible in this article to familiarize and summarize in detail the scienti c and organizational activities of Maria Gavrilova on the work of the Zolotinka geocryological station in 1975-1978.

The results of generalization and GIS integration of the results of the study of all known indigenous deposits and manifestations of diamonds located in the distributed and undistributed fund of the subsoil of the Russian Federation are presented. The work takes into account the results of prospecting, exploration and exploitation works, minutes of meetings of regional (TKZ) and federal (RKZ and GKZ) commissions on mineral reserves and published data. As a result, a GIS-integrated database was created containing 1,319 objects, for each of which key parameters were determined: coordinates, shape, size, age, average diamond content, forecast resources, and diamond reserves. It was established that the indigenous diamond deposits are concentrated in the Central Siberian subprovincia and account for 2.3 % of all known kimberlite bodies, diamond-bearing kimberlite bodies in the Yakut diamond-bearing province - 282, the predominant body shape is a pipe (59 %). There is no correlation between the size of kimberlite bodies and their diamond content, small pipes, as well as large diatremes, can be industrially diamondiferous, the prevailing absolute age of industrially diamondiferous kimberlites is 329-382 million years.

The article presents the results of the study by various geologists of the geological structure and prospects of ore-bearing trog complexes performing structures such as throgs, which were identi ed at di erent stages of geological research in the western part of theAldan-Stanovy shield. The main types of traction complexes and their sections were determined. The nature of the occurrence of sedimentary (terrigenous), volcanogenic- sedimentary and metavolcanic rocks performing throgs and forming throg complexes was established. The nature of the ratio of these rocks in the context of the trog complex in the studied trogs was described. The results of the study of trog complexes showed that they are generally characterized by facies variability, heterogeneity of metamorphism and dynamothermal processing of rocks (especially in the sides of trogs) with the formation of mylonites and cataclasites. It was established that the throgs are con ned to three regional systems of discontinuous disturbances. Both consonantal and secant discontinuities were marked inside the throgs, de ning their block tectonics. The results of determining the geological age of the rocks of the trogovoi complex were presented. The trog structures are characterized by ore mineralization associated with the processes of sedimentation (ferruginous quartzites, copper sandstones) and volcanogenic ore formation (copper-crusted and polymetallic mineralization), as well as with the processes of metamorphogenic-hydrothermal redistribution of ore matter (stratiform scheelite mineralization, ore-bearing quartz veins). It was also found that the metallogeny of the trog structures has not been studied su ciently. Nevertheless, the majority of geologists who studied the trogovye complexes noted in their reports that Precambrian trogovye complexes can be considered as important and metallogenically promising geological objects in the western part of the Aldan-Stanovy Shield and deserve more in-depth study.

A complex comparative study of diamonds from commercially productive diatremes of Daldyn- Alakitsky eld (Udachnaya, Zarnitsa) determined mineral typomorphic features, which allows diagnosing dispersion haloes of kimberlite material in sedimentary thick layers. By the set of typomorphic features, diamonds from Udachnaya pipe have many common features with crystals of other deposits of Daldyn-Alakitsky diamondiferous region. Increased content of variety II and III cubes, close by their features to diamonds from deep inclusions of eclogites, may be referred as inherent only to the Udachnaya pipe features. Zarnitsa pipe demonstarted pronounced prevalence of rhombic dodecahedral habit crystals of variety 1 with large concentration (> 30 %) of typically rounded diamonds. On the whole, diamonds of Daldyn eld are characterized by a complex of typomorphic features, which allow distinguishing them from diatremes of other diamondiferous regions of the Siberian platform with con dence.

The large amount of peaty soils on the territory of the Russian Federation, especially in the Arctic zone, necessitates the study of their temperature regime and thermophysical properties. The paper presents the results of an experimental study of the thermal conductivity and amount of unfrozen water in sandy soils with varying degrees of peat content. Experiments were carried out on samples with a damaged structure, which were represented by slightly decomposed peat, medium-grained river sand and their various mixtures. It has been established that the degree of peat content affects such physical values as porosity, thermal conductivity and the amount of unfrozen water. For thawed peaty sandy soils, as the degree of peat content increases, the porosity value increases. For both thawed and frozen peaty sand soils, thermal conductivity decreases with increasing degree of peat content. Moreover, the thermal conductivity for frozen soils are higher than for thawed soils. The amount of unfrozen water also depends on the degree of peat in the soil and decreases as it increases. The measured thermophysical properties of peaty sand soil can be used to model the temperature regime in the area of frozen and thawed peat soils.

This article contains data on the nature and level of study of the territories in which the north-eastern part of the Sakha Republic is located, which are potentially oil and gas bearing. In 1979-1992, seismic exploration of oil and gas was carried out in the Tastakh trough, the Zyryanka depression by JSC Yakutskgeofizika. The section of the Tastakh trough includes strata of terrigenous rocks of lithological unconstrained composition. Its capacity is 2.5-4.5 kilometers. The paper describes reflecting horizons based on Neogene-Quaternary, Jurassic-Cretaceous deposits. In addition, during the research, it was found that the Lower Cretaceous sediments present in the Tompon depression are divided by the Tomporuk-Kitchan zone of thrust divisions of the Late Cretaceous stage of activation of the Verkhoyano-Kolyma region. Upper Jurassic volcanogenic sedimentary rocks, Lower Cretaceous coal-bearing deposits are contained in the Zyryanka depression at 6 and 5 thousand meters, respectively. This article contains an opportunity for the allocation of time intervals, interpretation of sedimentary synchronous complexes of deflections, depressions, shelf. Seismic materials in these territories have a quality that can be recycled. The evidence of the need for this procedure appears during discussions on the topic of geological development, the structure of the mountain-folded Verkhoyano-Kolyma region, as well as the shelf that adjoins it. These data are confirmation of the presence of oil and gas in these territories. The work was carried out with the scientific equipment of the Center for Collective Use of the Federal research center ҺYakut Scientific Center of the Siberian Branch of the Russian Academy of Sciencesһ under grant No. 13.TsKP.21.0016. Support was received in the form of funds under the State Assignment from the Ministry of Science and Higher Education of the Russian Federation No. 122011100158-1.

This article considers the capabilities of the ground-penetrating radar (GPR) method in solving engineering geocryological problems at sites of placer mining operations in the permafrost zone. The methodology of conducting GPR measurements in the conditions of an active deposit is presented, taking into account those areas where continuous profiling is difficult. Its peculiarity lies in conducting measurements by angular GPR scanning (AGS) at individual points to assess the geocryological conditions of the rock mass. The features of the GPR wave fields of the geocryological section are considered. Interpretative characteristics are proposed that allow distinguishing signals reflected from the boundaries of frozen-thawed rocks. It has been established that reflection signals from thawed rocks are detected by an increase in their amplitude values and a shift of the central frequency of the spectrum to the low-frequency area compared to the characteristics of signals obtained when probing frozen rock areas. The results of geocryological studies in the Northern part of the Yakutsk diamondiferous province using GPR and drilling methods are presented. In accordance with the proposed interpretation features, wave fields were analyzed, and information from more than ten wells was used to confirm the interpretation: thawed rocks were detected in five wells. Based on the GPR data, a map of thawed rock distribution at depths of 1.5-5.9 m across the study area was constructed using seven profiles. The work was carried out within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation (topic No. 0297-2021-0020, of the unified state information system for recording research, development and technological work for civil purposes No. 122011800086-1) and the program of activities of the scientific and educational center “NORTH: Territory of Sustainable Development” for technological project No. 4: “Technologies for efficient and comprehensive extraction of useful components from mineral raw materials” using the equipment of the Center for Collective Use of the Federal research center ҺYakut Scientific Center of the Siberian Branch of the Russian Academy of Sciencesһ, grant No. 13.
