Background. In this paper, the authors aim to reveal the localization patterns of gold mineralization in the Phuok Son region of Central Vietnam, which formed a Proterozoic-Cambrian metamorphic complex in the zone of the Late Paleozoic Benzhang–Queshon granite block.Aim. To determine the localization patterns of gold mineralization in the Phuoc Son area, Central Vietnam.Materials and methods. The research was based on geological materials, as well as mine working and appraisal well data. The material composition of the materials was studied using 15 transparent sections and 18 polished sections. In total, 127 samples were subjected to atomic absorption spectroscopy.Results. Within the Phuoс Son gold ore field in Central Vietnam, the site of the Baidat and Baigo mines located in the zone of reverse-shear termination was investigated. Here, the gold ore bodies are represented by quartz-sulfide veins subparallel to schistosity. The ore-bearing zones are layered zones of tectonic faults, which formed at the end of the reverse-shear period and complicated the western limbs and locks of the anticlines. These zones were formed under regional sublatitudinal horizontal stresses. The horizons of carbonaceous quartz-sericite schists are of great importance in ore control. There are steeply dipping post-ore faults that displace ore bodies. Two gold mineralization stages can be distinguished. The early stage was characterized by a wide development of sphalerite and a smaller amount of gold. The later stage was associated with the main precipitation of gold and formation of galena. According to the geochronological data on the argon isotopy in biotite, the gold mineralization at Baidat and Baigo was probably formed in the Triassic (250–200 Ma ago), at the stage of extinction of the regional metamorphism of the Indosinian orogenyConclusion. The results obtained should be used when conducting local forecasting of gold deposits in Central Vietnam.

Background. Septaria, comprising calcareous-clay nodules with calcite veins, are widely used as jewelry and ornamental materials. Septaria from Morocco represented on the world and Russian markets of jewelry and ornamental stones remain gemologically and mineralogically underexplored. In this article, the gemological characteristics and mineral composition of Morocco septaria, as well as the conditions of their formation, are described for the first time.Aim. To determine the gemological characteristics and mineral composition of Morocco septaria, as well as their formation conditions. To conduct their comparison with septaria from other regions of the world.Materials and methods. The author studied the assortment of Morocco septaria presented at international and Russian exhibitions. A collection (15 samples) representing the main decorative septarium varieties was compiled. The materials underwent determination of microhardness, density, luminescence (10 samples), optical-petrographic analysis (4 sections), quantitative determination of mineral and chemical composition (2 samples), electron probe studies (2 samples).Results. The septaria were found to consist of (wt %): quartz — 38, goethite — 16, chlorite (shamosite) — 28, kaolinite — 6, siderite — 5, dolomite — 4, calcite — 1, pyrite, zeolite, apatite, hydrosludes less than 1. Dispersed inclusions of leucoxene, barite, and microcline were discovered. The septarium veins consisted mainly of dolomite, quartz, chlorite with inclusions of siderite, calcite and pyrite. The Zn, Sr, and Ba impurities ranged within 0.01—0.05 wt %, while Cr, V, Ni, Cu, Rb, Zr, Y, and Pb ranged within 0.001—0.01 wt %. The mineral composition of the studied Morocco septaria was found to differ significantly from that of septaria in other regions of the world, where calcite plays a decisive role.Conclusion. Morocco septaria of small size (from 2 to 6 cm) are used as interior decorations and jewelry cabochons. The mineral and chemical (including micro-inclusions and impurities) composition of Morocco septaria was established for the first time, which allows their identification. The mineral composition of the septaria under study is associated with the regional low-temperature metamorphism, which altered the original, predominantly calcite composition.

Background. The importance of studying the properties of argillaceous rock materials is determined by their widespread application in various industries. At the same time, identification of argillaceous minerals is associated with a number of difficulties.Aim. To study the properties of argillaceous rock materials collected in different sites by the method of simultaneous thermal analysis to reveal their characteristic patterns and to identify their composition.Materials and methods. Natural materials from different geographical sites in Russia and neighboring countries were studied by the method of simultaneous thermal analysis.Results. The use of simultaneous thermal analysis for studying the properties of argillaceous materials allows their behavior to be studied under temperature exposure. The composition of rock samples can be identified by comparing their thermogravimetric curves with those of known rocks.Conclusion. The possibility of using thermal analysis for identifying the presumed mineral composition of the studied rock material was established. However, the diversity of soils on the planet impedes drawing a definite conclusion about their mineral composition. Therefore, thermal analysis should be applied in combination with other research methods, such as XRD, sediment, optical, etc., analytical techniques.

Background. Underground uranium leaching is a promising geotechnological process due to its potential to provide for a radical increase in the technical and economic efficiency, as well as environmental safety, of uranium deposit development. In this article, we discuss the main results in this direction obtained by specialists of the Russian State University for Geological Prospecting.Aim. To study the processes of uranium leaching by activated solutions, which undergo electrophotochemical treatment prior to contacting with the ore.Materials and methods. Activation preparation of leaching solutions enables the synthesis of active hydrated forms of oxygen and hydrogen with collectivized protons and hydroxyl ions clustered by water molecules. Following the stage of pre-oxidation with an active carbonate solution, a model downhole leaching with chloride-hypochlorite, soda, and sulfuric acid solutions was carried out. Testing percolation leaching of uranium from the ores of the Uchkuduk and Sugraly deposits by activated solutions was conducted at laboratory installations designed by the the Russian State University for Geological Prospecting jointly with the Institute of Mining of Far-East Branch of the Russian Academy of Sciences and Zabaikalsky State University. As a result, the potential of a significant increase in uranium extraction was noted.Results. When leaching with sodium carbonate and ammonium carbonate solutions, the uranium extraction from ore samples from the Sugraly deposit comprised 52% and 59%, respectively. At the same time, the use of an activated solution of sodium percarbonate, which combines the functions of an oxidizing agent and a complexing agent, resulted in an 87–88% uranium extraction into productive solutions during 21 days without preliminary pre-oxidation.Conclusion. The results obtained confirm the prospects of using mine (block) and downhole uranium leaching with activated solutions.

Background. The development of the oil and gas industry in the Caspian region is closely linked with the development of oil and gas resources of the Caspian Sea and adjacent territories. According to historical sources, it was in the Caspian region where the global offshore oil production was launched. Further, other countries used the experience gained in the Caspian region. Four main stages can be distinguished in the of the Caspian oil and gas complex, including the nascent (antique and medieval eras) stage; the initial stage of industrial development (from the 10th century to 1917); the Soviet stage of industrial development; and the modern stage of industrial development.Aim. To study of the history of the development of the oil and gas industry in the Caspian region.Materials and methods. The methods of retrospective, graphical, statistical, system-structural analysis were used in the work.Results. Based on the results of the study, the main stages in the development of the oil and gas industry in the Caspian region were identified.

Background. Definition of local stratigraphical units, the main of which are formations, is important for geological mapping and correct understanding of the composition of sedimentary complexes. This task is yet to be solved for some territories. Thus, Upper Miocene deposits extend widely across the Rostov Dome in the southwest of Russia; however, the definition of formations there is still in its nascent phase.Aim. Systematization of ideas about the local stratigraphical units of the Upper Miocene of the Rostov Dome, taking previous assumptions into account.Materials and methods. An analysis of ideas related to the definition of formations in the Upper Miocene of the Rostov Dome was carried out. These ideas were systematized with a focus on the validity of the units based on the current stratigraphical code.Results. An improved local stratigraphical scale of the Upper Miocene of the Rostov Dome is proposed. This scale implies defining the Taganrogskaya (Lower Sarmatian), Rostovskaya (Middle–Upper Sarmatian), Donskaya (lower Upper Maeotian), Merzhanovskaya (upper Upper Maeotian), and Aleksandrovskaya (Lower Pontian) formations. The correspondence of alternative units is shown: the Mokrochaltyrskaya and Berdanosovskaya formations correspond to the Rostovskaya Formation, while and the later proposed Rostovskaya Formation corresponds to the Donskaya and Merzhanovskaya formations. Discussion. The validity of the proposed local stratigraphical units is noted; the priority of defining the Taganrogskaya and Aleksandrovskaya formations is highlighted. The question of creating an automatic system for generalizing information about stratigraphical units is discussed.Conclusion. The need in the parallel existence of alternative local stratigraphical scales of the Upper Miocene of the Rostov Dome is absent. However, subdividing the relevant deposits requires further discussion and refinement.

Background. Drilling vibrations may cause damage to the bit and early failure of downhole instruments. The main approach to solving this problem consists in measuring downhole vibrations while drilling by adding sensors near the bit in to the bottom hole assembly (BHA). When drilling vibrations are registered, measures are taken to avoid their reaching the critical values. If necessary the drilling stoops and the section is worked out to avoid accidents due to the high critical values. Not always drilling companies add such sensors to the BHA due to high price of the equipment. Constant problems with vibrations while drilling, require the creation of domestic low-cost autonomous equipment for measuring downhole vibrations and transmitting respective signals to the surface.Aim. To develop domestic low-cost autonomous downhole vibration measuring equipment.Materials and methods. Analysis of the experimental studies on drilling vibrations. Development technical solution such as domestic low-cost autonomous equipment for measuring downhole vibrations.Results. The problem of drilling vibrations can be controlled by downhole measuring equipment located in the vicinity of the bit. The device under development is presented in the article.Conclusion. In order to achieve maximum economic efficiency and avoid the costs of eliminating the consequences of vibrations, domestic low-cost autonomous downhole vibration measuring equipment should be developed to register torsional and longitudinal vibrations.

Background. The minerogenic specialization of the Muzkol-Rangkul anticlinorium consists in industrial gemstone deposits of ruby, cordierite, almandine, aquamarine, topaz, tourmaline, scapolite, etc. Large ore objects in this area are unknown. Until recently, the area has had a negative assessment in terms of rare, rare earth, and noble metals.Aim. To justify the identification of a previously unknown magnetic ring-type structure and to study the associated ore geochemical anomalies.Materials and methods. Rock and mineral samples collected at the Chernogorskoye deposit in 2016 and 2018 were examined. The mineral composition were determined using a Polam-R211 petrographic microscope and confirmed by XRD analysis using a DRON-3M diffractometer (analyst A.V. Fedorov, Sergo Russian State University for Geological Prospecting). The chemical composition of mineral samples was studied by X-ray microanalysis using a Cameca SX 100 instrument (analyst N.N. Kononkova, Vernadsky Institute of Geochemistry and Analytical Chemistry). The chemical compositions of rock samples was determined using an X-ray fluorescence spectrometer AXIOS Advanced (analyst T.G. Kuzminа, Vernadsky Institute of Geochemistry and Analytical Chemistry).Results. A ring-type intrusion composed of hornblende peridotites, hornblendites, and gabbroids was identified in the Muzkol-Rangkul anticlinorium, in the area of the Chernogorskoye gem scapolite deposit. The gabbroids here contact the metamorphic rocks of the Sarydzhilga formation along the ring fault. The geochemical anomalies of Co, Ni, W, Nb, Ti, and REE were revealed in the contour of the ring structure and along its periphery.Conclusion. The ring-type intrusion identified by the authors is a source of geochemical anomalies.
