It has been established that, compared with sedimentary rocks in general, the Bajossian deposits are characterized by low contents of Ni, Pb, Cu, Co, Zn, Mn and higher contents of V, Cr. The conducted research is of practical importance and useful in the search for minerals, as well as in the study and protection of the environment, ecologists, etc. Keywords: Greater Caucasus, Bajocian deposits, trace elements, statistical distributions, concentration clarks.

According to whole-rock indicators (Sr/Y > 40, Sr > 420 ppm, Y < 15.5 ppm) and indicator features of zircons (Eu/Eu* = 0.28, Yb/Dy = 3.7) from monzonite-, quartz-syenite-, and granite-porphyries and oxygen fugacities calculations (avg. ΔFMQ +0.48), the Kultuma granitoids were evolved from hydrous, moderately oxidized magmas. However, the oxidation state of the magmas was insufficient for productive porphyry mineralization to occur. Keywords: zircon, geochemistry, granitoids, Kultuma intrusion, skarn deposit, porphyry mineralization, Eastern Transbaikalia. Р.11-19 |

It is concluded that they are associated in the deflection with the presence of several structural tiers, disharmonious folding due to the presence of plastic clays of the Maikop series in the section, high density of local structures of the main and additional folding, the backstage articulation of their periclinals, small size and amplitude of structures of additional folding, a large number of discontinuous disturbances, complex seismogeological and landscape conditions, low the resolution of the seismic survey of the MOV OGT, as well as various ideas about the mechanism of formation of structural elements of the deflection. Keywords: regional deflection, structural tier, structures of the main folding, structures of additional folding, oil and gas complex, rupture, field, oil gas, complex of geological exploration work.

The article analyzes the conditions for the long-term preservation of ancient fortification structures of the Karelian Isthmus and the possibility of their museumification on the example of the Tiversky settlement and the Korela fortress, taking into account the peculiarities of the engineering-geological conditions of the southern part of the Baltic Shield. The authors take into account climatic changes, the role of tectonic processes in the formation of the river network, and analyze the processes developing in the foundations and structures of monuments. Keywords: engineering-geological conditions, architectural-archaeological monuments, museumification. Р. 32-38 |

(National University of Uzbekistan named after Mirzo Ulugbek) // kamila-kh@mail.ru MINERALOGICAL AND GEOCHEMICAL STUDIES OF THE GOLDEN MINERALIZATION OF SHARYKTY (CENTRAL KYZYLKUM) In the Central Kyzylkum, in the Daugyztau ore field, there are numerous small occurrences of gold, which may be of interest for industrial mining in connection with the more advanced technologies for beneficiation of gold-sulfide ores being developed in Uzbekistan, taking into account world experience in the development of small crowded deposits. To study the industrial significance of the Sharykty ore occurrence, studies were carried out to study the mineral composition of ores and near-ore rocks, to identify the forms of finding gold and silver, and the nature of the distribution of useful components in ores. Productive mineral associations for gold and accompanying mineralization have been identified; determine the forms of finding gold and other useful components in ores using modern analytical equipment.

The classification of criteria in the suggested scheme is given in the form of five evaluation blocks, each of which can be used as a stage of a comprehensive evaluation of a region’s mineral resources, or be applied individually for the solution of separate tasks. The characteristics of the criteria and the methods of their mathematical visualization are given.
