Abstract:
The term “geochemical barrier” (GCB) has been widely used in the Russian geochemical literature as a key concept of the distribution of elements and substances theory (incl. pollutions)although in the world research practice this term is not particularly represented. The assessment of the functional role of the geochemical barriers in relation to the properties and evolution of the geochemical systems (GCS)is demonstrated.The foundations of Haken synergy, the foundations of self-organization of systems and non-equilibrium (non-linear) thermodynamics of I. Prigogine and his school are used as a methodological framework. From the authors’ point of view, GCB are considered as self-organizing components of GCS, in which physical and chemical processes are activated, leading to the transformation of atomic and molecular structures, chemical associations and individual chemical elements under the impact of active media (processes). They can be the defining phenomenon of the emergence and evolution of GCS. The concept of geochemical barriers is the foundation for technologies that are actively implemented for cleaning and protecting soils, groundwater and surface water, and the geological environment in general.

Abstract:
The geochemical characteristics of volcanic flows of Nakora area of Malani Igneous Suite have been determined to understand their magmatic evolution and petro-genetic aspects. Geochemically, they are high in silica, total alkalis, high field strength elements (HFSE), low ion lithophile elements (LILE), rare metals and rare earth elements; represent A-type affinity with potential mineralization associations. Here, we carried out average geochemical data bank of representative samples of 44 individual lava flows of isolated hill-locks. The relative enrichment of trace elements and negative anomalies of Sr, Eu, P and Ti in the multi-element spider diagrams suggests that the emplacement of the lava flows was controlled by complex magmatic processes i.e. fractional crystallization, partial melting, magma mixing, crustal contamination and assimilation. Moreover, NRCmagma provides new geochemical approaches to understand geodynamic evolution of MIS and emplaced in plume related extensional geodynamic settings in NW Indian shield.

Rapien, Maria H. "Geochemical Evolution at White Island, New Zealand." Thesis, Virginia Tech, 1997. http://hdl.handle.net/10919/36832.

Abstract:
White Island, New Zealand, is an active andesitic volcano that is located near the southern end of the Tonga-Kermadec Volcanic Arc at the convergent plate boundary where the Pacific Plate is being subducted beneath the Indian-Australian Plate. The plate tectonic setting, volcanic features and the petrology of White Island are thought to be characteristic of the environment associated with formation of porphyry copper deposits. White Island has only been active for about 10 Ka and, as such, is thought to be an ideal location to study early magmatic processes associated with formation of porphyry copper deposits. In this study, the geochemistry of the silicate melt at White Island has been characterized through detailed studies of silicate melt inclusions, phenocrysts, and matrix glass contained in recent ejecta (1977-1991). Most melt inclusions contained only glass, however, daughter minerals present in multiphase melt inclusions in the 1991 sample indicate a different P-T history compared to the other samples. Samples studied are vesicular porphyritic andesitic dacites containing phenocrysts of plagioclase, orthopyroxene, and clinopyroxene. A glassy matrix containing crystallites surrounds the phenocrysts. Both mineral and silicate melt inclusions occur in all three phenocryst phases. Inclusions of plagioclase occur in pyroxenes and inclusions of orthopyroxene and clinopyroxene occur in plagioclase. Compositions of minerals are independent of mode of occurrence - that is, plagioclase (and orthopyroxene and clinopyroxene) compositions are the same regardless of whether they occur as phenocrysts or as inclusions in another mineral. Moreover, compositions of mineral inclusions and phenocrysts show no systematic variation within individual samples or in samples representing different eruptive events, indicating that the magma chamber is chemically homogenous over the time-space scale being sampled. Various major, trace element and volatile compositional features of economic and non-economic (or barren) porphyry copper systems were compared to the White Island data. The Al2O3/(Na2O+K2O+CaO) ratio observed in economic porphyry copper deposits is always greater than or equal to 1.3, and glass in one phase melt inclusions, as well as glass in unhomogenized (1991) inclusions from White Island equal or exceed this value. The glass in the unhomogenized 1991 melt inclusions is corundum normative, with Si/(Si+Ca+Mg+Fet)>0.91, and K/(K+Ca+Mg+Fet)>0.36, all of which are characteristic of productive systems. Melt inclusions from White Island also show a positive Eu anomaly similar to that found in productive porphyry deposits, whereas non-productive systems show a negative Eu anomaly. Copper concentrations (170-230 ppm) in melt inclusions from White Island are sufficiently high to generate an economic porphyry copper deposit based on theoretical models. High Cl/H2O ratios (0.15) in melt inclusions furthermore indicate that copper will be efficiently partitioned from the melt into the magmatic aqueous phase. The inferred pressure in the magma chamber at depth (1 kbar) is ideal for extracting copper from the melt, and mineral phases (pyrrhotite, biotite or amphibole) which could scavenge copper before it could be partitioned into the magmatic vapor phase are absent. Concentrations of S in the melt are also low, which would prevent pyrrhotite from crystallizing. The tectonic setting and geochemical characteristics of the magma body at White Island are similar to features observed in economic porphyry systems elsewhere. These data suggest that development of economic porphyry copper mineralization at White Island is likely.

Abstract:
The PhD thesis is focused on the hydrogeology and geochemistry of the surface and groundwater in Liverpool area. It provides a detailed understanding of the effect of the structural geology on the groundwater flow and the geographical variation in the groundwater geochemistry. Moreover, the studies have extended the research towards the geochemical evolution of the fresh and saline groundwaters and surface water. The main conclusions are that the major structural elements, especially the NNW-SSE major faults and a gentle NE-SW fold, have subdivided the aquifer into discreet six hydrogeological sub-basins. As a result of this, a single groundwater flow direction in the aquifer is not likely existed; multiple local flow directions are expected instead. The recharge of the aquifer sub-basins is mainly by vertical percolation while the lateral mixing between the different water types and the inland invasion of seawater are limited by the major faults. The aquifer has two major types of groundwaters. Fresh groundwater occupies one part, generally a few kilometres from the coast and saline groundwater in another part that has undergone seawater intrusion from the Mersey Estuary. The recharge of the fresh groundwater is mainly localised from surface waters (originally rainfall). The recent recharged groundwaters are expected in spatially restricted areas with low salinity and they broadly resemble surface waters except they are more acidic possibly due to C02 dissolution and dissociation, nitrification or sulphide oxidation. This immature groundwater evolved into the regionally dominant groundwaters through a combination of congruent dissolution of dolomite, cation exchange and sulphate mineral dissolution happening in the Sherwood Sandstone aquifer. Due to locally advanced stage of water rock interaction, the regionally dominant groundwater has evolved into higher salinity fresh groundwater at the southern end of a southward flowing compartment. Close to the urban heart of Liverpool the groundwater has undergone local pollution as reflected by the elevated salinity, Cl, S04 and N03 concentrations, The origin of the saline groundwater is mainly due to seawater intrusion based on the similarity in chemical composition between the saline groundwater and River Mersey water. This study has shown that highly saline groundwater has been expected in the Sherwood sandstone aquifer underneath Liverpool and close to the River Mersey. From the previous and present works the saline groundwater in this part of the aquifer mainly due to saline water intrusion from Mersey Estuary. This has been based on the geographic distribution and chemical affinity between the saline groundwater and Mersey Estuary water. The invaded Estuary water experienced a wide range of geochemical processes that deviates the composition of the water away from being a simple physical mixture between low salinity groundwater and seawater. During progressive invasion by seawater, it seems that cation exchange (Na-capture and Ca release) occurs first with a small amount of carbonate and even anhydrite cement dissolution. Next, cation exchange becomes relatively less important but bacterial sulphate reduction starts to occur. The final process during the later stages of saline invasion seems to be dolomitization of indigenous calcite accompanying more advanced bacterial sulphate reduction and with relatively minor cation exchange. The chemistry of the surface water has been studied in small river systems in the area (River Alt, Downholland Brook and River Alt). The main recharge of these surface waters is local rainfall. Dissolution of calcite and weathering of silicate minerals are the most common processes operating in a higher relief river basin floored by Sherwood Sandstone (Calder River regime), while the abundance of gypsum and calcite with silicate in the Downholland Brook and River Alt bed rocks explain the increase of the total dissolved salts and ionic composition of the former two streams waters. The continuous influx of atmospheric CO2 and H+ ions from the dissociation of H2C03 increases the ability of these waters dissolving minerals in contact especially carbonates and silicates. The concentration and lateral variation of the nitrate concentration in the surface and groundwaters have been studied trying to assess its possible source and fate. The results reveal that a significant part of nitrate in surface and groundwater is coming from the application of fertilizers in addition to urban waste water in the highly populated areas. Nitrification process in the soil zone transforms the N-compounds (eg. NH4) into nitrate. The direct drainage of soil water to the river course carries high nitrate to the river waters. The low nitrate concentration in the locally-recharged groundwater is mainly due to natural denitrification processes probably in the unsaturated and saturated zone however the high abstraction rate of the groundwater could be responsible for yielding water with high nitrate concentration.

Abstract:
Dans mon projet, j'ai utilisé les gaz nobles (He, Ne, Ar, Kr et Xe) pour étudier les processus naturels se déroulant dans différents contextes géodynamiques (c.-à-d. subduction, collision continentale, rifting), montrant ainsi comment l'utilisation des gaz rares est fondamentale pour contraindre l'origine des substances volatiles et comment ils permettent une évaluation qualitative et quantitative des processus (interaction eau-gaz-roche) qui se produisent pendant la remontée des fluides de l'intérieur de la Terre vers l'atmosphère. Les résultats de mon projet peuvent être résumés en cinq thèmes principaux : 1) Aperçu de l’histoire du dégazage du manteau terrestre à partir d'analyses de haute précision des gaz rares du gaz magmatique ; 2) Systématique des gaz nobles et des isotopes du carbone sur le volcan Ciomadul, apparemment inactif (Roumanie): Preuve du dégazage volcanique ; 3) Fluides dérivés du manteau dans le bassin sédimentaire de Java oriental, Indonésie ; 4) Dégazage des volatiles du manteau dans un régime tectonique de compression hors du volcanisme: rôle de la délamination continentale ; 5) Dégazage continental de l'hélium dans un contexte tectonique actif (nord de l'Italie) : le rôle de la sismicité
In my project, I used the nobles gases (He, Ne, Ar, Kr and Xe) to investigate natural processes occurring in different geodynamical contexts (i.e., subduction, continental collision, rifting), showing how the use of the noble gases is fundamental to constrain the origin of volatiles, and to investigate the Earth interior. Furthermore, I also used these volatiles to recognize the processes (water-gas-rock interaction) that occur during the fluids up rise from the Earth’s interior to the atmosphere and quantitatively constrain the extents of these processes. The results of my project are summarized in five main topics: 1) Insights into the degassing history of Earth’s mantle from high precision noble gas analysis of magmatic gas 2) Noble Gas and Carbon Isotope Systematics at the Seemingly Inactive Ciomadul Volcano (Romania): Evidence for Volcanic Degassing 3) Mantle‐Derived Fluids in the East Java Sedimentary Basin, Indonesia 4) Outgassing of Mantle Volatiles in Compressional Tectonic Regime Away From Volcanism: The Role of Continental Delamination 5) Continental degassing of helium in an active tectonic setting (northern Italy): the role of seismicity

Abstract:
Glass Buttes complex lies at the northern margin of the Basin and Range province in central Oregon and is cut by the northwest-trending Brothers fault zone. An older acrystalline volcanic sequence of high-silica rhyolites (>75% SiO2) forms a broad platform composed of domes and flows with minor pyroclastic deposits. The high-silica rhyolite sequence is divided on the basis of texture into 1) zoned flows and domes, 2) obsidian flows, 3) felsite flows, and 4) biotite-phyric flows and domes.

Full text
Abstract:
AbstractProduced water was sampled and measured repeatedly during production from an offshore field, and an extensive brine chemistry dataset was developed. Systematic analysis of this dataset enables an in-depth study of brine/brine and brine/rock interactions occurring in the reservoir, with the objective of improving the prediction and management of scale formation, prevention and remediation.A study of the individual ion trends in the produced brine, using the types of plot developed for the Reacting Ions Toolkit (Ishkov et al., 2009), provides insights into what components are involved in in situ geochemical reactions as the brines are displaced through the reservoir, and how the precipitation and dissolution of minerals and the ion exchange reactions occurring within the reservoir can be identified. This information is then used to better evaluate the scale risk at the production wells.A thermodynamic prediction model is used to calculate the risk of scale precipitation in a series of individual produced water samples, thus providing an evaluation of the actual scaling risk in these samples, rather than the usual theoretical estimate based on endpoint formation and injection brine compositions, and the erroneous assumption that no reactions in the reservoir impact the produced water composition. Nonetheless, the usual effects of temperature, pressure and brine composition are accounted for in these calculations using classical thermodynamics. The comparison of theoretical and actual results indicates that geochemical reactions taking place in this given reservoir lead to ion depletion that greatly reduces the severity and potential for scale formation. However, ion exchange reactions are also observed, and these too affect the scale risk, and the effectiveness of scale inhibitors in preventing deposition.Additionally, comprehensive analysis using a geochemical model is used to predict the evolution of the produced brine compositions at the production wells, and to test the assumptions about which in situ reactions are occurring. A good match between the predictions from this geochemical model and the observed produced brine compositions is obtained, suggesting that the key reactions included in the geochemical model are representative of actual field behaviour. This helps to establish confidence that the model can be used as a predictive tool.
