AbstractThe deep structure of the Earth’s crust and the surface of the mantle lithosphere of the East European platform are considered. In the three main layers (lower, middle, and upper) of the Earth’s crust, as well as in the surface of the mantle lithosphere, deformations expressed in the changing thickness of the layers have been identified for...

AbstractThe engineering-geological features of the sands included in pre-Quaternary continental terrigenous formations (red and gray, coal-bearing and lignite-bearing, molasse and molasse coal-bearing), which are widespread in Russia, are characterized. The results of studying the composition, structure, condition, and properties of these soils wit...

AbstractThe results of the isotope dating of the crystalline basement of the Greater Caucasus (the Elbrus subzone of the Main Caucasus Range) within of the high-temperature gneiss–migmatite area of the Gondaray metamorphic complex is discussed. The relationships between regional metamorphism, migmatization, and heat flows in the lithosphere are con...

AbstractExperiments were carried out on fluorine leaching from rocks (alkaline agpaitic granite, dacite, and feldspar–quartz aleurite with 0.005 M solutions of acetic, tartaric, citric, and oxalic acids. The previously revealed decrease of fluorine leaching with organic acids compared to distilled water under an acidity increase within the 6.3–3.5 ...

AbstractConsiderable amounts of menshikovite (the rare palladium–nickel arsenide Pd3Ni2As3) have been found at the eastern flank of the Oktyabrsky deposit (Norilsk ore field) near the contact of solid and impregnation sulfide Co–Ni–Cu ores within the magnetite–plagioclase–fassaite skarns. The sulfide material of the ores consists of aggregates of c...

Abstaract—Two methods of sample preparation (microwave assisted acid digestion and sintering with sodium bicarbonate) of materials with complex compositions, including organic components for ICP-MS elemental analysis, were tested. The samples used included terrigenous clay (SDO-1), volcanic-terrigenous silt (SDO-2), calcareous silt (SDO-3), ferroma...

AbstractQuality control by hidden works in artificial soils is a relevant problem in construction engineering. Seismoacoustic methods are widely used for its solution. In this work, seismoacoustic well logs in artificial soils manufactured by the jet grouting technology were processes to obtain additional data on the distribution of heterogeneities...

AbstractThe major lithological rock types that compose the highest-carbon part of the lower Silurian Longmaxi Formation section in the Sichuan province of the People’s Republic of China have been identified and characterized. The analyzed distribution of rare and trace elements in graptolite shales has made it possible to propose the redox conditio...

AbstractAt the current level of differentiation of sciences, the achievements of each of them can be compared with a quote taken out of context. We know that such a procedure is highly risky since it may change the main message fundamentally. In the framework of epistemology, the context is the totality of the results of all sciences, i.e., all mod...

Abstract—The hydrogeochemical composition of groundwater of the Bodrak River basin (the territories of the geological student training courses of St. Petersburg State University, Moscow State University, and the universities of Dubna and Voronezh) has been studied. The role of the lithological composition is determined for the formation of the hydr...
