Identification of structural control factors of primary gold ore occurrences by method of unmanned aeromagnetic survey by the example of the Neryungrisky district of Yakutia

Abstract

The long-term development of the geophysical industry, in which the methods of magnetometry are in maximum demand, as the simplest in instrumental and methodological execution, has determined the development of remote measurement methods implemented both from space and airborne carriers. The necessity to use the latter as an obligatory component of field surveys, providing coverage of significant areas, determines the need for using the unmanned low-tonnage carriers. Their use is implemented to search for predictive elements of structural (spatial, genetic) control of endogenous gold ore occurrences that allow predictive constructions, i.e., solving the problem of increasing gold reserves, which is being performed within the framework of federal programs. The purpose of the survey is to develop a system of instrumental and subsequent interpretation approaches in the organization of unmanned magnetometer survey, implemented for structural and geological mapping by the example of the Neryungrinsky district of Yakutia. Within the framework of the digital model formation of the relief and the anomalous magnetic field, a survey method using an unmanned aircraft, its technical characteristics are considered; the analysis and the author's modification of the office analysis of magnetometry data are performed. Based on the obtained materials, a physical and geological model of the investigated area was created, which is presented in the form of a geological and structural cut, accompanied by the physical characteristics of the structural and material complexes. The refinement of the physical and geological model was implemented by a joint morphostructural analysis of the remote base and the anomalous magnetic field using the results of quantative interpretation of the anomalous magnetic field. The result of the study is presented by an updated geological basis with the allocation of promising ore sites for their detailing as part of the planned large-scale geological and geophysical surveys. The scientific novelty of the work consists in the synthesis of the tried and tested methods of unmanned aeromagnetometric measurements and geostructural reconstructions, which allow the processing of both potential and non-potential geofields.

Humanitarian knowledge in higher education: On the issue of training scientific and scientific-pedagogical personnel (on the example of graduate ecologists)

“…The "physical" and "emotional» models of participatory training have been portrayed in order to develop the potential of highly motivated and well-educated graduate ecologists being diminished by the lack of ability to apply their knowledge [21]. Environmental issues of global warming and greenhouse effect continue to call for the attention of the international community and increasingly cry out for the adoption of attitudes and signs of solidarity with the help of carbon dioxide sequestration technologies, which are implemented as CC(U)S (carbon capture, utilization and storage) projects involving the capture, disposal and, in some cases, use of CO [22,23].…”

Effect of Copper, Zinc and Molybdenum Micro Elements in Plants When Using Granular and Liquid Nitrogen Fertilizer with Micro Elements Made from Local Raw Materials

“…Mirzajonov (2014) [15], F.Hoshimov (2017) [16], A. Sanakulov (2018) [17] and other scientists conducted scientific and research work. Finding various sources of microelements as fertilizers, studying various industrial wastes, solving problems of testing are of great importance [18,19].…”

Evaluation of Displacements Caused by Strike-Slip Deformations Using Correlation Characteristics Based on Potential Field Data

“…Tectonic-magmatic and disjunctive factors associated with faults, including strike-slip nature, affect the localization of orebearing structures [Alekseev, 2020[Alekseev, , 2021. The structure of ore bodies is often controlled by shears [Arkadiev, 1969;Movchan et al, 2022], since emerging spalls and cracks form a void space for ore deposition in a well-permeable zone [Il'chenko et al, 2022;Yakovleva et al, 2022]. Tectonic disturbances of shear nature form wide zones of increased rock fracturing, which can be significant in assessing the quality of facing stone [Isakova et al, 2021], in studying the stability of structures or mine workings [Kazanin et al, 2021].…”
