Summary This article discusses the possibilities of using the express method for preliminary assessment of the geomechanical structure of construction sites - the combined method of standing waves (RAP). The above examples show the real results of work carried out on construction sites in Turkey and Russia. The results of comparison of the results of the RAP with other methods of geophysics are also presented. Comparison results show good convergence between RAP data and other methods. Based on the above examples, the authors conclude that the use of express methods of geophysics at the initial stage of engineering surveys will significantly increase the efficiency of research while generally reducing the time for performing engineering surveys.

Summary The purpose of this work is obtain additional information about the features of fluid inclusions, which makes it possible to cl arify the thermobarochemical parameters of the processes that contributed to the formation of the ore bodies of the Chertovo Koryto deposit. It was carried out inclusions in different types of quartz, their composition, cryotermetric studies, and the data obtained was compared with those already known to determine thermobarogeochemical criteria for the difference between ore and post-ore quartz. Gold-bearing quartz-sulphide veins were formed from a fluid characterized by a temperature of the order of 380–440 ° C, and a salinity of a solution of 4 wt. % NaCl-eq. With the active participation of carbon dioxide. At an early stage, gold was carried by a carbon dioxide fluid formed as a result of carbon decarbonisation during the destruction of the organic matter of the enclosing black shale deposits with their subsequent localization on geochemical barriers. Post-ore quartz veins were formed due to a fluid with a temperature not exceeding 160 °C and salinity of the solution not exceeding 2.0 wt. % NaCl-eq., with a significant decrease in the proportion of carbon dioxide in the gas component and an increase in the proportion of N2 and CH4. The predominant role of CO2, CH4 and N2 in the composition of inclusions is a reflection of the confinement of quartz veins to black shales with a significant content of organic matter.

Summary In the world of software, engineers and developer are empowered but tool chains that help them craft, re-use, share and build on their previous work and the work of others. That process of extending and remixing previous work is integral to the software power leaps in technology that we see around us. Imagine equipping scientists with a tool chain of their own? customised to their needs and enabling in the same way re-use, sharing, remixing and rapid publication. Such a tool chain could well take us towards a tipping point in open science. At Curvenote we are building such a toolchain, by connecting scientists' writing directly to their computational tools and through a collaborative environment, we help stop wasted time and effort, make it easier to build on previous work and provide a traceable path from a figure in a paper back to the code and data that produced it. Such a tool chain can both accelerate progress and significantly improve reproducibility of work.

Summary A variety of landslides such as mud flow, rock fall and rock avalanche can be detected with Distributed Acoustic Sensing (DAS). The consequences of the event and the preliminary signs of its development can be assessed by Distributed Strain Sensing. The combination of DAS and DSS instrumentation in the Geotechnical Monitoring System (GTMS) helps to mitigate geohazard risks along infrastructures crossing challenging environments.

Summary This article is aimed at studying new ways of forming predictive and prospecting models for the localization of ore objects. For this purpose, the text discusses the possibility of applying the classification technique of potential fields together with the transformation of the initial geophysical data, for further identification of the most interesting anomalous structures. Based on the results of studying the a priori information, the following transformations are performed: the division of the source maps into regional and local components, the calculation of the transformants of potential fields. Based on the identified identical features, the fields are classified using the Coscad 3D program, both for each field individually and for the combined model. As a result, a comprehensive analysis of the original and converted geoinformation is performed. The authors substantiate the patterns of distribution of the most interesting structures, draw conclusions about the prospects for the development of the method of classification of potential fields, when solving problems of interpretation of geophysical data.

Summary Currently, there are no normative maps of general seismic zoning of the water areas of the inland and marginal seas of Russia, especially since there are practically no maps of detailed seismic zoning and seismic micro-zoning even for individual parts of the water areas. Taking into account the fact that intensive development of offshore oil and gas fields and the Northern Sea Route has begun, the development of such maps is becoming a very urgent scientific and practical task. This article substantiates the need to use bottom seismological observations when performing work on detailed seismic zoning (DSZ) and seismic microzoning (SMZ) of water areas.

Summary The capabilities of application of the controlled source radiomagnetotelluric (CSRMT) sounding method with a horizontal electrical dipole as a source in the solving of various tasks in the permafrost areas are considered. The possibility to study permafrost geoelectric sections at industrial construction sites is demonstrated. In the Yakutia kimberlite province the tasks of studying the morphology of dolerite sills within the overlying sediments and mapping the roof of kimberlite hosting carbonate rocks were solved. Based on the simulation results, the possibility of mapping the under-channel and sub-lake taliks is shown. In this case, using the tensor modification of the CSRMT method with two multidirectional sources and bimodal inversion of the data are preferable. The CSRMT method has some advantages over conventional DC methods used in the permafrost areas (VES, ERT). This is a higher productivity of work and the ability to perform soundings in the winter on snow and ice. Compared to the TEM soundings and GPR, the CSRMT method provides more reliable results in the depth interval from 5 to 15 m, when the GPR lacks depth, and TEM has problems in detailing the upper part of sections at early recording times.

Summary In article a karst as dangerous engineering-geological process is considered. It is discussed a question of karst typing on open mine deposits of gypsum plaster. In context of karst danger by morphological and morphometric parameters the karst typing is proposed, for example of Sokolino-Sarkaevsk deposit. Examples of practical application are given, which show, that modern impact and karst forms typing very largely allow to decrease a risk of human traumatism and technics damage at mining on the open mine deposits of gypsum plaster.

Summary Experimental research was carried out in order to improve diagnostics methods of roads operated in cryolitic zone. Results of ground-penetrating radar diagnostics at the Vilyui federal highway in Central Yakutia are presented. Data was obtained by OKO-2M GPR with AB-400 antenna unit (LogiS LLC). Attributes for interpretation of GPR wave fields are developed based on characteristics of GPR signals propagation in the road soils. Further it is used for mapping various cryogenic structures. For example, to identify water invasion zones at boundaries of the structural layers of the road surface and the roadbed, to determine zones of soil decompression at the subgrade support, to identify areas of swelling soils. As a result, GPR monitoring as part of engineering and geological survey allows reasonably plan and carry out actions to eliminate and prevent various types of subsidence and destruction of road surfaces, as well as to assess the nature and level of negative cryogenic processes.
