  • Geochemistry of granitoids from the basement of the Kuril island arc
    • Abstract: This paper reports the characteristics of granitoids from the Pacific slope of the Kuril island arc system, which were discovered by the authors during geological and geophysical operations in three cruises of the R/V Akademik M. Lavrent’ev. The major and trace element compositions of these rocks were determined, their role in the formation of the submarine Vityaz Ridge was evaluated, and they were compared with granitoids from the Brouton group of submarine volcanoes and xenoliths from Simushir Island and the Sea of Okhotsk. Granitoids from various structures of the basement of the Kuril island arc system are hypabyssal rocks derived from andesite magmas. Their common features are related to the formation on the continental crust under convergent geodynamic conditions involving compression due to the movement and subduction of the Pacific plate beneath the Asian continent. The problem of the basement of the Kuril island arc system was discussed, the composition and age of its rocks were determined, and the history of the geologic development of the Pacific slope of the arc starting from the Late Mesozoic was briefly described.

  • Molecular nitrogen in salts and subsalt fluids in the Volga-Ural Basin
    • Abstract: Analysis of the distribution and genesis of nitrogen in salts and subsalt formation fluids in the Volga-Ural Basin makes it possible to distinguish two genetically distinct groups of subsalt fluids and corresponding two distinct sources of nitrogen. One of them includes calcium chloride bridnes, nitrogen-saturated oils, and nitrogen-bearing formation gases. The fluids of this group have δ15N > 0‰ and occur closer to the surface in the platform part of the basin. The other group comprises only oils saturated with CH4 and methane formation gases, and the fluids of the latter group likely have δ15N < 0‰ and were found near the margin of the platform, in the Ural Foredeep and near the Caspian depression. The first group with isotopically heavy nitrogen is supposedly formed by fluids remaining after the loss of volatile components during ancient metamorphism of the rocks, whereas the second group was likely generated by the volatiles released during the degassing of the same rocks.

  • REE and fluid inclusions in zoned fluorites from Eastern Transbaikalia:
           Distribution and geochemical significance
    • Abstract: Special methodology was used to study the distribution of REE and some other elements in zoned fluorites from the different deposits of Eastern Transbaikalia. Fluorites from the uranium and polymetallic ore fields sharply differ in their REE distribution pattern and the composition of fluid inclusions, which reflects the geochemical specifics and indicates the possible sources of parental solutions. A gradual change in REE distribution patterns established in the successive growth zones of fluorites clearly coincides with the gradual decrease of temperature and mineralization of fluid inclusions. It is suggested that a change in the REE distribution pattern was provoked by the crystallochemical differentiation related to the formation of nano-sized mineral admixtures of REE phosphates and/or fluorcarbonates, which possess an ability to the selective accumulation of different REE groups. It was found that the zoned fluorites from the Streltsovka and Garsonui deposits show an opposite trends in the change of REE pattern with zonation. With a general decrease in total REE contents, fluorite from the Streltsovka deposit shows a change from positive parabolic to subchondritic pattern, while that from the Garsonui deposit, varies from the negative via subchondritic to the positive patterns.

  • Geochemistry of metamorphic processes in mafic rocks of the Krasnaya Guba
           area, Belomorian Mobile Belt
    • Abstract: New data are obtained on the major-component and minor- and trace-element composition of metamorphosed gabbronorites and Fe-Ti gabbro in the Krasnaya Guba area, Belomorian Mobile Belt. These two magmatic complexes, which are spatially combined but are of different age and were produced in different geodynamic environments, were simultaneously metamorphosed in the Paleoproterozoic to parameters transitional between the amphibolite and eclogite facies. Eclogite metamorphism was associated with perceivable changes in the concentrations of alkalis and alkali earth elements, and the metamorphic transformation of the plagioclase eclogite (which can be metamorphosed gabbronorite and/or gabbro) into amphibolite and biotite amphibolite was associated with changes in the concentrations of practically all trace elements. This implies that the metamorphic processes were not isochemical and were accompanied by significant removal and introduction of incompatible elements. However, some trace-element ratios (such as Ti/Y, Ti/Zr, Zr/Y, La/Sm, and Nb/Th) remained unmodified in the course of metamorphism and remained the same as in the pristine gabbronorite or gabbro and likely can be employed as indicators of the composition of the probable protolith and the conditions under which it was produced.

  • Change in the degree of catagenesis and hydrocarbon generation in the
           sedimentary rocks of the South Sumatra Basin, Indonesia
    • Abstract: Temperature and catagenetic history of the South Sumatra Basin in Indonesia is considered by the example of the sedimentary sequence of the Limau graben during its subsidence from the Oligocene to the present time. GALO system for basin modeling was applied for numerical reconstruction of six sedimentary successions in the area of holes Pandan-81, Petanang-1, Tepus-2, Tepus-1, Gambir-1, and Lembak-8 located along the profile cutting across the Limau graben. Modeling suggests significant cooling of the basemen for the last 15–20 Ma from the high initial heat flow of 105 mW/m2, which is typical of axial zones of continental rifting, and significant heating of the basin lithosphere during the last 2–5 Ma. Examination of variations in tectonic subsidence of the basin confirms the possible extension of the lithosphere in the Oligocene-Miocene with an amplitude β increasing from 1.12 on the flanks of the Limau graben (Hole Lembak-8) to 1.32 in the central part of the graben (Tepus-1 and 2), Tectonic analysis indicates also the notable thermal activation of the basin in the Pliocene, Pleistocene, and Holocene. This activation is consistent with the high temperature gradient typical of the present-day sedimentary cover of the basin. Numerical modeling of the evolution of the organic matter maturity and hydrocarbon generation by main source formations of the basin confirms good prospects of the inferred source formations (Lemat, Talang Akar, and Gumai) of the South Sumatra basin for the generation of liquid hydrocarbons (HC) in the Limau Graben. It is also demonstrated that the source rocks of the Lemat Formation are ore-generating rocks in the main part of the Limau graben and are gas-generating rocks only in the deepest portions of the graben. The rocks at the base and roof of the Talang Akar Formation could be considered as highly oil-generating rocks, probably except for the upper horizons of the formation in the shallowest portions of the graben (Hole Lembak-8). Oil generation reached peak in the last 5–10 Ma. Modeling showed that intense oil generation by the Gumai Formation may be significant in the most part of the Limau graben and negligible only in the distant flanks of the graben (Hole Lembak-8).

  • The tritium-helium-3 method and its application to groundwater dating by
           the example of the Kirovsk mine region, Murmansk oblast
    • Abstract: The measurement of 3H, 3He, 4He, and 20Ne concentrations in waters at the Tsentralny pumping station (southern Khibiny massif, Kola Peninsula) showed that they are a mixture of young (>90%) and old (<10%) waters. The excess noble gas component from the young water is caused by the dissolution of air bubbles trapped during recharge in the unsaturated zone. The 3H-3He(3H) age of the young water is 21 ± 1.5 yr. The U-Th-4He age of the old water is about 50 ka. The high concentrations of helium and some toxic elements (e.g., aluminum) in this old water are caused by dissolution of the alkaline rocks of the Khibiny massif as a result of water-rock interaction.

  • Migration of dissolved trace elements in the mixing zone between Volga
    • Abstract: Based on natural observations over many years, the distribution of dissolved nutrients and trace elements was analyzed in the mixing zone between the freshwater of the Volga River and Caspian seawater. Most of the trace elements (Li, Rb, Cs, B, F, Br, I, Ga, Sc, Y, Co, Ni, Cu, Cd, Ag, V, As, Sb, Bi, Mo, W, and U) show a conservative behavior. During the period of the highest bioproductivity, dissolved phosphates and silica are intensely removed from solution (up to 60–90 and 46–82% of their supply by river runoff, respectively) mostly owing to uptake by aquatic organisms. The distribution of dissolved strontium was assigned to the weakly nonconservative type, because a minor excess of its content above the lines of conservative mixing (8–18%) was observed in some years; perhaps, this is related to different water transformation at the areas of moving and stagnant water in the delta and offshore mouth zone. Barium is characterized by additional input into the solution (up to 52%) in the regions of medium salinity owing to ion exchange reactions in the absorbed complex of river suspended material. The migration of dissolved species of aluminum, manganese, and iron in the mixing zone of Volga and Caspian waters is probably controlled by the coagulation and flocculation of organic and organo-mineral colloids, which is indicated by a sharp decrease in the content of these elements during the initial stage of salinization (59, 91, and 74%, respectively) followed by a plateau. The most complicated distribution was observed for titanium, lead, and rare earth elements (REE), the concentrations of which showed intense removal from the solution (up to 64–88% Ti, 52–87% Pb, and 66–83% REE) followed by a gradual increase, which is probably related to the elevated contents of these elements in the water of the northern Caspian above a local minimum in the zone of active flocculation of colloids.

  • Seasonal and interannual variations of water chemistry in the headwater
           streams of the Angara River (Baikal) from 1950 to 2010
    • Abstract: The study addressed seasonal and interannual variations in the components of the trophic status (organic carbon, nitrogen and phosphorus; silica; suspended matter; and chlorophyll-a) and ionic composition (bicarbonates, sulfates, chlorides, calcium, magnesium, sodium, and potassium) in the headwater streams of the Angara River since the 1950s. The results show that the concentrations and seasonal variations of these components and long-term trends of their mean annual concentrations resulted from the interplay of biological, hydrological, and anthropogenic processes operating in Lake Baikal and reflect the current ecological state of the lake.

  • Magmatic sources of dikes and veins in the Moncha Tundra Massif, Baltic
           Shield: Isotopic-geochronologic and geochemical evidence
    • Abstract: The dike-vein complex of the Moncha Tundra Massif comprises dolerites, gabbro-pegmatites, and aplites. The dolerite dikes are classified into three groups: high-Ti ferrodolerites, ferrodolerites, low-Ti and low-Fe gabbro-dolerites. The U-Pb age of the ferrodolerites is 2505 ± 8 Ma, and the amphibole-plagioclase metagabbroids hosting a ferrodolerite dike are dated at 2516 ± 12 Ma. Data on the U-Pb isotopic system of zircon from the gabbro-pegmatites and titanite from the aplites indicate that the late magmatic evolution of the Moncha Tundra Massif proceeded at 2445 ± 1.7 Ma, and the youngest magmatic events in the massif related to the Svecofennian orogeny occurred at 1900 ± 9 Ma. The data obtained on the Sm-Nd and Rb-Sr isotopic systems and the distribution of trace elements and REE in rocks of the dike-vein complex of the massifs provide insight into the composition of the sources from which the parental magmas were derived. The high-Ti ferrodolerites were melted out of a deep-sitting plume source that contained an asthenospheric component. The ferrodolerites were derived from a mantle MORB-type source that contained a crustal component. The parental melts of the gabbro-dolerites were melted out of the lithospheric mantle depleted in incompatible elements after Archean crust-forming processes above an ascending mantle plume, with the participation of a crustal component. The gabbro-dolerites and the rocks of the layered complex of the Moncha Tundra Massif exhibit similar geochemical characteristics, which suggest that their parental melts could be derived from similar sources but with more clearly pronounced crustal contamination of the parental melts of the rocks of the massif itself. The geochemical traits of the gabbro-pegmatites are thought to be explained not only by the enrichment of the residual magmas in trace elements and a contribution of a crustal component but also by the uneven effect of sublithospheric mantle sources. The aplites were derived from a sialic crustal source.

  • Sequence of geologic events in the central and northeastern parts of the
           Lapland Granulite Belt: Isotopic geochemical zircon data and results of
           geological-petrological studies
    • Abstract: Geological and petrological studies of rocks were conducted to reproduce the succession of endogenic processes in the central and northeastern parts of the Lapland Granulite Belt along the course of the Lotta River. Mineralogical-geochemical data on zircon from these rocks (the anatomy of zircon crystals seen in BSE and CL imagery; U, Th, Hf, and Y concentrations; and REE patterns) and their crystallization temperatures (calculated using the Ti concentration) make it possible to correlate the newly obtained geochronologic data with the sequence of metamorphic events inferred from petrological data. Three major episodes of enderbite-forming processes are distinguished: (i) early episode at 1.99 Ga, (ii) main episode at 1.940–1.925 Ga; and (iii) late episode at 1.89 Ga. The early medium-pressure metamorphic episode is dated at 1.97–1.96 Ga. The diatexis of the quartz-feldspar granulites with the derivation of garnet plagioclase leucogranites took place at 1.917–1.909 Ga.

  • Iodine and selenium speciation in natural waters and their concentrating
           at landscape-geochemical barriers
    • Abstract: Drinkable waters in Bryansk oblast are generally poor in I and Se. Possible I and Se speciation in the drinkable waters and their means of migration and concentration in soils at geochemically contrasting conditions are analyzed, and the possible reason for the high mobility of I is demonstrated to be predetermined not only by its occurrence in the form of iodide and organic complexes but also by solute mineral species (CaI+ and MgI+), with the former and the latter types of the complexes spread more widely in the polessky and opolny landscape types, respectively. Iodine complexation with alkali-earth cations under reduced neutral-weakly alkaline conditions facilitates, on the one hand, vertical iodine migration and, on the other hand, its precipitation on the carbonate barrier. The predominant solute species of Se in these environments is hydroselenide, which can form FeSe in the presence of significant Fe concentrations and be precipitated on the reduced barrier in soils of hydromorphic landscapes. The generally low total I and Se concentrations in the drinkable waters and the migration of solute compounds of radioactive I in the form of organic and inorganic complexes could likely result in a higher thyroid morbidity rate over the whole territory of Bryansk oblast, including areas contaminated with radioactive I isotopes after the accident at the Chernobyl nuclear power plant.

  • Estimation of the thermodynamic characteristics of the earth’s core
           using the embedded atom model
    • Abstract: Since there are only limited experimental data for the multicomponent composition of the Earth’s core, which may contain nickel, silicon, sulfur, oxygen, hydrogen, carbon, and other admixture elements, we applied the molecular dynamics method as an additional tool. This approach is currently limited to the analysis of one- and two-component systems. In order to estimate the validity of this method for modeling under the Earth’s core conditions, a hypothetical variant of core composition corresponding to the iron-sulfur binary system was considered, because there are sufficient experimental data for this system under low-pressure conditions. The proposed embedded atom potential allows adequate description of the thermodynamic properties of solid and liquid iron-sulfur solutions under the conditions of the Earth’s center, inner-outer core boundary, and core-mantle boundary. The calculations relied on the Preliminary Reference Earth Model (PREM) data for pressure and density of phases at the inner-outer core boundary. Molecular dynamics calculations showed that the hypothetical variant of iron-sulfur binary solutions can provide reasonable consistency with the PREM values of pressure, density, and sound velocity for all the above levels. For this variant, temperatures at the same levels and sulfur contents were determined. The sulfur content was constrained at 5 at % in the inner core and 11–12 at % in the outer core, and it is almost independent of coordinates in each part of the core. The uncertainty of the calculation of sulfur content is ±0.5%. For the accepted two-component variant, the calculated temperature is approximately 6700 K in the Earth’s center and 6325 K at the inner-outer core boundary; the temperature estimate for the core-mantle boundary is more uncertain and ranges from 3300 to 4325 K (the latter value is more probable). The deviation of the calculated sound velocity from the PREM data is 5–10%, and the calculated velocity is overestimated at the core-mantle boundary and underestimated at other levels. If sufficient experimental data are available, a similar computation method can be applied to other two-component models of the composition of the Earth’s core (for instance, iron-nickel, iron-silicon, iron-oxygen, etc.), whereas three- and multicomponent systems cannot currently be calculated using the molecular dynamics method. The calculations reported in this paper showed that the molecular dynamics method in combination with geophysical data allows us to analyze different hypothetical variants of the composition of the Earth’s core, provides additional information on the properties of the core material, and helps to reveal the variants of core composition that are inconsistent with the available natural data.
