AbstractThe Late Jurassic orogenic volcanogenic–plutonogenic Darasun gold deposit (the Eastern Transbaikalian segment of the Mongolia-Okhotsk Foldbelt) includes post-gold antimony mineralization. Aggregates of rice-like quartz, minerals of the jordanite–geocronite–schulzite series, sphalerite, galena, arsenopyrite, tennantite–tetrahedrite, calcite,...

AbstractThe results of the hydrogeochemical study of poorly mineralized thermal groundwaters from the Kuldur Spa (Jewish Autonomous Region, Russia) are reported. These groundwaters are distinguished by their high temperature (73°С), low TDS (up to 0.38 g/L), and alkaline environment (pH 9). The dominant cation is sodium, and the dominant anion is h...

AbstractThe middle Miocene (mainly the Konkian) shallow marine sediments of Eastern Georgia (Eastern Paratethys, Kura basin) have been studied for the first time with cyclostratigraphy methods. Time series analysis (Lomb-Scargle and REDFIT periodograms, Gaussian filter) revealed a statistically significant signal with a 2.4–2.7-m wavelength, which ...

Abstract—An analysis of modeling the mineralization zones of stockwork ore deposits indicates that the inclusion of barren rocks in a mineralization zone has little effect on the downward bias of the component content estimates. On the contrary, the extreme component contents that often occur among the exploration data influence the bias of compone...

AbstractIn recent years, significant success has been achieved in the search for and exploration of oil and gas reservoirs in the Jurassic deposits on the eastern side of the Fukang Depression, which is the least studied part of the Junggar oil and gas basin. In order to determine the hydrocarbon generation source, we have studied source rocks, oil...

AbstractThe resistivity method is widely used in shallow surface geophysics. Capacitive resistivity is one of techniques that extend the use of the resistivity method for an environment where galvanic coupling of electrodes is difficult, for instance, frozen ground, hard rocks, and engineered structures (roads, railways etc.). This technique allows...

AbstractThe Siratur gold deposit occurs in the northern part of the South Uralian segment of the Main Uralian Fault. The ore zone of the deposit is confined to an area of a tectonic junction of serpentinites of the Nurali massif and a longitudinal band of carbonaceous schists of the Ordovician Polyakovka Formation, which also hosts abundant basalts...

AbstractThe study of the foraminiferal communities from the Paleogene–Neogene reference section at Kvachina Bay in West Kamchatka has made it possible, based on the qualitative composition and the quantitative ratios of the encountered species, to identify 13 layers with foraminifera corresponding to certain intervals of the section and to establis...

AbstractThe structures and geological history of the shelf of the East Siberian continental margin are considered on the basis of the interpretation of seismic data along with geological data. The main structural constituents of the East Siberian Sea that were formed under the Barremian–Aptian rifting processes are described: the New Siberian rift;...
