Abstract

Application of the thermodynamic principles of chemical petrology and solution chemistry to the study of geochemical processes permits prediction of the consequences of reaction between aqueous solutions of electrolytes and typical igneous, metamorphic, and sedimentary mineral assemblages. A given geochemical process can be represented by a set of reversible and irreversible chemical reactions that corresponds to an array of linear differential equations relating partial equilibrium and nonequilibrium in thermodynamic systems. Simultaneous evaluation of these equations defines the nature and extent of the compositional change and redistribution of species in the aqueous phase, the order of appearance of stable and metastable phases, and the mass transfer resulting from irreversible reactions between the minerals and the aqueous solution.

Advanced argillic alteration at Cave di Caolino, Lipari, Aeolian Islands (Italy): Implications for the mitigation of volcanic risks and the exploitation of geothermal resources
2023, Science of the Total Environment
Four sites in the western sector of Lipari Island with still active hydrothermal activity are here considered. The petrography (mesoscopic observations and XRPD) and geochemistry (major, minor and trace elements chemistry) of ten representative and extremely altered volcanic rocks were characterized. Two types of parageneses of altered rocks are discriminable, one rich in silicate phases (opal/cristobalite, montmorillonite, kaolinite, alunite and hematite) and one in sulphates (gypsum, plus minor amounts of anhydrite or bassanite). The altered silicate-rich rocks are rich in SiO₂, Al₂O₃, Fe₂O₃ and H₂O, and depleted in CaO, MgO, K₂O and Na₂O, while the sulphate-rich ones are extremely enriched in CaO and SO₄ in comparison with local unaltered volcanic rocks. The content of many incompatible elements is similar in altered silicate-rich rocks and lower in sulphate-rich ones with respect to the pristine volcanic rocks; conversely, almost all REEs are markedly enriched in silicate-rich rocks and heavy REEs are enriched in sulphate-rich altered rocks compared to unaltered volcanic rocks.
Reaction path modelling of basaltic andesite dissolution in local steam condensate predicts the production of amorphous-silica, anhydrite, goethite, and kaolinite (or smectites and saponites) as stable secondary minerals and alunite, jarosite, and jurbanite as ephemeral minerals. Considering possible post-depositional reactions and admitting that the presence of two distinct parageneses is apparent, since gypsum is prone to form large crystals, it can be concluded that there is an excellent agreement between the alteration minerals occurring in nature and those predicted by geochemical modelling. Consequently, the modelled process is the main responsible for the production of the advanced argillic alteration assemblage of “Cave di Caolino” on Lipari Island. Since rock alteration is sustained by the H₂SO₄ solution produced by hydrothermal steam condensation, there is no need to invoke the involvement of SO₂-HCl-HF-bearing magmatic fluids, in line with the absence of fluoride minerals.
Conceptual model for the chemical evolution of groundwater in a region of the Canadian Precambrian shield covered by soft Quaternary deposit of glacial and marine origin
2023, Applied Geochemistry
The present study presents a conceptual model of the chemical evolution of Canadian Shield groundwater that includes major, minor and trace elements. Four (4) stages of the natural chemical evolution of groundwater are examined: Stage 1- infiltration of rainwater; Stage 2- evolution of recharge water, Stage 3a-salinization by Water/Rock interaction, and Stage 3 b-salinization by Water/Clay interaction. The approach proposed is based on a standard of reference called the ‘Water Maturation Index’ (WMI) that establishes standardized concentration values for specific chemical elements occurring in groundwater. The WMI was developed to describe the natural process of multiparameter enrichment/depletion through ongoing salinization from a reference water (rainwater in this study). It is concluded from our study that to better understand the mixing dynamics and contribution of compositional hydrogeochemical poles (endmembers) in an area of the Canadian Shield that has experienced a post-glacial marine event, a groundwater sampling campaign should minimally include the major elements: chlorides, bicarbonates, sulphates, sodium, potassium, magnesium and calcium, to which should be added in all cases the minor and trace elements: iron, manganese, bromides, lithium, strontium, boron, fluorides, molybdenum, nitrite-nitrate, ammonium and silica. Analyzing all these elements together would allow a better understanding of the origin of the chemistry of sampled groundwater, without necessarily requiring isotopic analyses. This study also highlights the importance of using a passive or low-flow sampling protocol to limit anthropogenic disturbance of the natural environment during sampling. Finally, this study improves an existing conceptual model of the chemical evolution of groundwater for the study area.
Modeling reactive multi-component multi-phase flow for Geological Carbon Sequestration (GCS) with Matlab
2023, Computers and Geosciences
We present a reactive multi-component multi-phase flow program for simulating Geological Carbon Sequestration (GCS), an approach that reduces carbon emissions by storing ${CO}_{2}$ in deep subsurface formations. The program, called MRST_CO2, is implemented in the library Matlab Reservoir Simulation Toolbox (MRST). It can simulate multi-phase flow and transport of species undergoing chemical reactions and mass exchanges among gas, liquid and solid phases. Equations for flow, mass transport and chemical reactions are solved with a sequential iteration approach. The program was tested with a 1D benchmark. It has also been applied to heterogeneous 2D and 3D cases with a structured or unstructured grid.
Hydrogeochemical and isotopic characterization of the Gioia Tauro coastal Plain (Calabria - southern Italy): A multidisciplinary approach for a focused management of vulnerable strategic systems
2023, Science of the Total Environment
This work pursues the hydro-geochemical and isotopic characterization of the complex groundwater system of the Gioia Tauro Plain, one of the most important industrialized and agricultural coastal areas of southern Italy. The anthropic pressure exposes the water resources at risk of depletion and quality degradation making the plain groundwater a system of high scientific and social interest.
The plain is characterized by a shallow aquifer, mostly recharged by local rains and a deep aquifer apparently less influenced by local precipitation. Both aquifers are mainly Ca-HCO₃ waters except for localized sectors where Na-HCO₃, Na-Cl and Ca-SO₄ waters are present. In deep aquifer, both prolonged interaction with sedimentary rocks, mainly deriving from the erosion of crystalline rocks, and direct cation exchange represent the primary factors controlling the formation of Na-HCO₃ waters. Mixing processes between these waters and either connate brine and/or deep thermal waters contribute to the formation of isolated high salinity Na-Cl-rich waters. In shallow aquifer, inputs of N-rich sewage and agriculture-related contaminants, and SOx emissions in proximity of the harbor are responsible of the increasing nitrate and sulphate concentrations, respectively. The Cl/Br and NO₃/Cl ratios highlight contamination mainly linked to agricultural activities and contribution of wastewater.
Along the northern boundary, the warmest groundwater (Na-Cl[SO₄]) were found close to a bend of the main strike-slip fault system, locally favouring the rising of B- and Li-rich deep waters, testifying the influence of geological-structural features on deep water circulation.
Despite the high-water demand, a direct marine intrusion is localized in a very restricted area, where we observed an incipient groundwater-seawater mixing (seawater contribution ≤7 %). The qualitative and quantitative conditions of the shallow aquifer still have acceptable levels because of the relatively high recharge inflow. A reliable hydrogeochemical conceptual model, able to explain the compositional variability of the studied waters, is proposed.
Bulk composition and thermal evolution constrain the formation of organics in Ceres' subsurface ocean via geochemical modeling
2023, Icarus
Ceres is the largest object in the asteroid belt and the only dwarf planet in the inner solar system. In 2015, carbon, and organic compounds, were found by the Dawn mission in high abundance in the surface of Ceres. Here, we use thermodynamic modeling with the goal of constraining the speciation, stability, and abundance of organic compounds formed via abiotic reactions in the early subsurface ocean of Ceres and its mud-bearing mantle. We vary environmental conditions such as temperature, pH, reduction potential, solution composition, and pressure to analyze the variables that lead to optimal formation of organics. Primary results predict that in-situ organic production is negligible for most cases in the subsurface ocean if Ceres primarily accreted CI carbonaceous chondrites yet may be more significant if Ceres formed from cometary material. Carbonate concentration is 3–6 orders of magnitude higher than organics in the chondritic models, while a cometary composition favors significant alcohol and carboxylic acid derivative production, among other organic species. Results also indicate that temperature and pH are drivers of organic formation by water-rock equilibrium, with temperature having the greatest effect. Further analysis reveals that a mixture of ≲ 80 wt% CI chondrite and ≳ 20 wt% cometary material is favorable to in situ organic production of reduced organics. Observational constraints from the Dawn mission indicate that our model results could be representative of the organic observations on the surface. While our models favor organic production in Ceres' ocean with moderate amounts of cometary material, further studies into alternative mechanisms of production and concentration on the surface of Ceres are needed.
Through a glass, darkly: Trying to understand geothermal systems by means of geothermometers and f<inf>CO2</inf>-indicators
2022, Journal of Geochemical Exploration
There are three classes of geothermometers and f_CO2-indicators (collectively known as geoindicators): the traditional or classical ones, the theoretical activity-based geoindicators, and multicomponent chemical geothermometry. Most traditional geothermometers (e.g., SiO₂, NaK, Na-K-Ca, KMg) are linear functions linking the logarithm of the equilibrium constant of the controlling reaction to the absolute temperature reciprocal. Total concentrations are considered in most traditional geothermometers. Thanks to these two characteristics, the traditional geothermometers are simple to be used, which explains their widespread use. However, there are at least two issues which have been disregarded or not properly considered in the derivation of traditional geothermometers. One is that total concentrations of relevant solutes can deviate considerably from the activities of the aqueous species participating to the controlling mineral-solution reactions due to the formation of aqueous complexes. The other concerns the hydrothermal minerals, with some having variable composition and adularia being affected by AlSi order-disorder on the tetrahedral sites. To overcome these two issues, theoretical activity-based geoindicators were recently proposed. To use these geoindicators is necessary to run a speciation program, but computed temperatures and CO₂ fugacities are more reliable than those given by traditional geoindicators and additional information is obtained on the hydrothermal minerals present in the geothermal aquifer. Multicomponent chemical geothermometry consists in simulating the heating of the aqueous solution of interest from the P-T conditions present at the surface to those occurring in the geothermal aquifer. Both multicomponent chemical geothermometry and theoretical activity-based geoindicators call for the use of a suitable computer code and an internally consistent thermodynamic database. It would be desirable for the database to be shared, accepted and used by the entire scientific community.
