AbstractForms of metals in water and bottom sediments of the Malaya Sen’ga River located in Petushinskii district of Vladimir oblast have been analyzed. It is shown that all the studied metals in the river waters are predominated by their dissolved forms. Most of the Fe, Cu, Cd, and Pb form complexes with organic substances, which are mainly repres...

AbstractWe have made an attempt to reconstruct a pre-erosion structure of the Monchegorsk layered intrusion and to assess the parent magma (melt) composition and crystallization conditions. The problem has been solved by simple comparison of the Monchegorsk intrusion structure with a similar analog, that is, the Kivakka layered intrusion, and by mo...

AbstractA complex geophysical and mathematical model of the Norilsk metallogenic region, consisting of fifteen levels of hierarchy, was constructed using the method of automatic express interpretation of areal geophysical data developed by the authors. The model is based on the mathematical approach of fuzzy logic, including artificial neural netwo...

AbstractVysotskite is widespread in the Noril’sk-I deposit of Co–Ni–Cu sulfide massive and disseminated (“amygdaloid”) ores affected by posttrap low-grade metamorphism under conditions of prehnite–pumpellyite and zeolite (lomontite) facies, in association with ferruginous chlorite, babingtonite, ilvaite, greenalite, millerite, cummingtonite, gruner...

AbstractRocks in the Galitsyno quarry located in the Adler region of the North Caucasus are described. The quarry is of interest, because the excellent exposure in the relatively homogeneous carbonate rock sequence makes it possible to identify certain changes that reflect events that were common to the Late Cretaceous, in this case, the Late Campa...

AbstractThe assessment of the water-physical parameters of soils by indirect geophysical indicators is rather simple and enables the characterization of environmental objects of various volumes. This article presents the results of the determination of kinematic parameters of elastic waves in clay soils with different values of the liquidity index....

AbstractNew results of thermobarogeochemical studies show that quartz veins in the Drazhnoe deposit were formed under mesozonal conditions at a depth of 3–9 km from heterogeneous carbon dioxide–aqueous fluids with a low concentration of brines and high contents of CO2, which is typical of ore-forming fluids in orogenic vein gold deposits. Based on ...

AbstractBased on previously obtained hydrochemical data on the reservoirs of the Moscow Canal, the Uglich, Rybinsk, Sheksna, Vytegra, and Belousovo reservoirs along with Lake Onega, thermodynamic calculations were carried out for the forms of the occurrence of trace elements in the waters of these basins. It has been shown that the prevailing forms...

AbstractOne of the key problems in oil and gas geology is the problem of the development of thin-layered undersaturated reservoirs. Based on selected analogous fields the required methods for their effective development have been specified. In order to comprehensively analyze the reservoir and to reduce risks during its development, 4D geological a...

AbstractA representative collection of Zapolyarnaya pipe diamonds of the first commercial production batch has been studied by the IR, PL, and EPR morphological analysis methods. The medium–low-N diamonds are the most similar to Daldyn–Alakit diamonds (Yakutia) in terms of their composition and ratios of impurity centers. The typomorphic features o...
