ORE DEPOSITS OF RIFT STRUCTURES
The article presents the geology, history of development and ore content of rift structures of different ages, which include rift systems of oceanic spreading zones, continental and intercontinental rifts, as well as greenstone belts. A comparative analysis and comparison of these structures showed that, despite the different geo-tectonic position, conditions and time of their formation, the processes
of ore formation are fundamentally similar. The manifestation of pre-Phanerozoic rifting processes has been established within the tectonically weakened Baikal-Stanovoy zone of the southern border of the Siberian formation and the East European craton, during which large ferruginous-quartzite deposits, as well as gold, copper, rare, etc. were formed. metals. The article concludes with data on
the geology and manifestation of modern hydrothermal sedimentary ore formation in the silts of the seabed of the riftogenic structure of the Red Sea, which can be considered as a natural laboratory for understanding the conditions for the formation of productive riftogens of previous geological epochs.
Keywords: rifting, deep processes, hydrothermal-sedimentary ore formation.

DISTRIBUTION OF URANIUM RESOURCES
IN THE GEOLOGICAL HISTORY OF THE EARTH
Тhe results of calculations of uranium resources in deposits of various ages are presented, highlighting groups of endogenous and exogenous. It is shown that the maximum accumulation of uranium in the deposits of these groups does not coincide in time, but correlates with certain stages in the geological history of the Earth and the development of its biosphere. Attention is drawn to the need for further research in this direction.
Keywords: uranium, resources, deposits, endogenous, exogenous, the history of the Earth.

GEOLOGICAL AND STRUCTURAL POSITION AND SOURCES OF FORMATION OF THE JALINDINSKY
UNIQUE PLACER SYSTEM OF THE PRIAMUR GOLD-BEARING PROVINCE
Information is given about the large Jalindin placer system of the Amur gold-bearing province, which is located in the Solovyov ore-placer node of the Yankan metallogenic zone of the Amur gold-bearing province. About 200 tons of gold were extracted from placers of this system, which is 24% of the extracted placer gold of the province. The characteristic of placers, including the uniquely rich placer of the Jalinda river, is given. It has been established that the source of placer formation is a stockwork of numerous gold-bearing quartz veins, zones of veined quartz formation and quartz veins, measuring 15 × 20 km, dated to the Jalindin granitoid
intrusion of Early Cretaceous age. The description of the Kirovsky and Solovyevsky gold ore deposits located within the stockwork of the gold-sulfide-quartz formation is given.
Keywords: province, ore-placer node, placer, gold deposit.

JEWELRY AND ORNAMENTAL SEPTARIES OF THE REPUBLIC OF KABARDINO-BALKARIA. MINERAL COMPOSITION, GEMOLOGICAL CHARACTERISTICS
Septaria — calcareous-clay nodules with calcite veins are widely used as jewelry and ornamental material. Products from the septaria of the Republic of Kabardino-Balkaria have appeared on the Russian market, the results of the study of which are presented for the first time in the article. Septaria are associated with the deposits of the lower Aptian. They consist mainly of calcite (80.1% by weight), quartz, illite, albite, barite, chlorite, microcline, inclusions of anatase, kaolinite and pyrite are present. Of the impurity elements in the septaries, Sr contents (0.0309 wt.%) are recorded. Stable Mg, Mn and Fe contents have been established in calcite from impurity elements, which differ in differently colored layers and in marl. The established mineral and chemical composition of the septaries allows their identification. Septaries have a wide range of sizes, high decorative and positive technological characteristics, which makes it possible to produce a diverse range of products, including jewelry. Septaria can be collected in large volumes in river valleys without significant material costs and environmental disturbances.
Keywords: jewelry and ornamental raw materials, septaries, deposits of Aptian, calcite, Republic of Kabardino-Balkaria.

ASSESSMENT OF ENGINEERING AND GEOLOGICAL PROCESSES IN THE EXPLORATION OF ORE DEPOSITS IN CENTRAL KYZYLKUM
The article considers engineering-geological processes during open-pit mining and exploration by the mine method, in which unfavorable processes and phenomena develop: collapse, fallout and weathering of rocks on the slopes of the sides of quarries and in underground mine workings, which is most characteristic of interbedded dislocated shale strata. According to the engineering and geological conditions of mining, the deposit is divided into three groups: Tamdytau, Auminza-Beltau and Auminzatau. The reason and characteristics of the development of deformation processes are given, depending on the geological-structural, geological, and climatic factors that predetermine the development of the formation of deformation processes.
Keywords: collapse, fallout, weathering, predictive assessment, eolian, deformation, roof, workings, crosscut.
