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.

One of the ways to obtain information about the cryogenic state of rocks by GPR is based on the analysis of the in-phase axes of signals reflected from local objects. On the images of GPR radargrams, similar in-phase axes are represented by hyperbolic curves. On the basis of their localization and refinement of the form, the speed of passage of an electromagnetic wave in the medium is determined. To refine the shape of the hyperbolic curve in the developed algorithm, methods based on the Hough transform were used. To optimize the performance of the algorithm, restrictions on the dimensions of the original and accumulator spaces are introduced. The boundaries of the original space were determined on the basis of previous studies on the detection of hyperbolic axes of common-mode signals. The dimension of the Hough space was reduced on the basis of a priori knowledge of the possible allowable speed of electromagnetic waves in the medium. As a result of the work of the created software, the speed of propagation of an electromagnetic wave in space above the local object and the real part of the complex relative permittivity are calculated, which makes it possible to determine the electrophysical properties of the medium. Testing of the developed algorithm was carried out on the results of field georadar measurements and synthetic data. The accuracy of the results of the algorithm was 98.6 %, which indicates the adequacy of its applicability for studying ice in permafrost layers.

The Basin of the Vilyui river is located on the territory of Western Yakutia, one of the most developed and industrialized parts of Yakutia, which is of great economic and strategic importance for Russia. The region is the center of the diamond mining industry of the Russian Federation, where primary and alluvial diamond deposits are developed, a cascade of hydroelectric power stations is located on the river Vilyui. This causes environmental and social problems, negatively affecting all components of the natural environment. It is necessary to study the stability of northern landscapes to technogenic impact and study the hydrobiological state of aquatic ecosystems, in particular, the state of the algoflora of watercourses. As a result of studying the degree of stability of landscapes in the basin of the river Vilyui to technogenic impact on permafrost and bioclimatic indicators, the degree of their resistance is determined. It was revealed that, according to the permafrost characteristics, the northern taiga open forest and haze landscapes are defined as predominantly weakly resistant, the middle taiga as medium resistant. The most unstable in terms of bioclimatic indicators were mountain-tundra landscapes, characterized by the coldest and most humid conditions. As a result of studies of the current hydrobiological state of the rivers in the basin of the river Vilyui determined the low development of phytoplankton and phytoperiphyton in the river Irelyakh, M. Botuobuya and in the upper reaches of the river Vilyui, consisting of a monotonous species composition of diatoms and green algae. The maximum average number of algae varies from 82290 cells/l to 20700 cells/l, the highest biomass was noted in one area and is 1.58 mg/l. The Shannon-Weaver biodiversity index varies by sampling points along the river. Vilyuy from 0.19 bits / copy. and 1.00 bits/copy. up to 2.40 bits/copy. According to the sanitary-biological characteristics, mass species-indicators of water saprobicity were identified, which indicates the III class of water purity, as moderately polluted. Thus, it was determined that the state of phytoplankton and phytoperiphyton is under the influence of the technogenic load of diamond mining and hydropower enterprises.The work was carried out according to the state assignment on the topic “Vegetation cover of the permafrost zone of the taiga Yakutia: biodiversity, habitat-forming functions, protection and rational use” (scientific topic code: FWRS-2021-0023; draft state task (No. FWRS-2021-0014) of the program in the priority area of the PFNI RF for the long-term period (2021-2030).
