Seasonal quantification of carbonate dissolution and CO2 emission dynamics in the Indian Sundarbans estuaries

Shifts in carbonate dissolution can help understand the exchange of carbon dioxide between the air and water of estuarine systems. Adequate spatial coverage is required to understand these emission dynamics. Hence, the distribution of carbonate parameters in three estuaries covering a vast expanse of the Indian Sundarbans is described from total alkalinity (TA), dissolved inorganic carbon (DIC) and pH data collected between 2016 and 2020. The seasonal impacts on inorganic carbon parameters were also studied by comparing pre-monsoon, monsoon, and post-monsoon data compiled from the study period. The estuaries showed the highest TA (up to 2506μmol kg −1) and DIC (up to 2203μmol kg −1) in the pre-monsoon. Both the parameters overall were positively associated with salinity. TA and DIC decreased by 369 and 208μmol kg −1, respectively, in the monsoon compared to pre-monsoon. From the monsoon to the post-monsoon, TA and DIC increased by 121 and 85μmol kg −1, respectively. Both showed strong positive associations with high chlorophyll- aand high dissolved oxygen in the post-monsoon suggesting an important role of primary production in the estuaries in raising the concentrations of inorganic carbon parameters. The carbonate mineral saturation states (ΩCa and ΩAr) followed the same pattern as that of TA and DIC. The pair was always supersaturated although freshwater influence caused the values to drop to close to saturation. While pCO2was mostly supersaturated in the system relative to atmospheric concentration, it became minimal in the post-monsoon corresponding to heightened primary production. Despite high organic carbon recycling in mangroves, the system showed less expression in terms of CO2 emission in a seasonal cycle. Overall, the Indian Sundarbans estuarine system emitted low amounts of CO2 with its estimated water-to-air flux densities varying from 0.40 ± 0.61 (pre-monsoon) to 1.62 ± 1.74 mmol m−2h−1(monsoon).

Dissolution dynamics of NaCl at the atomic scale

Insulating films such as sodium chloride (NaCl) are ideal platforms for studying single atoms and single molecules as decoupling layers. The NaCl dissolution process has been extensively studied, and has become an increasingly important scientific problem. However, the understanding of defect dynamics in the NaCl dissolution process at the atomic scale is still in the exploratory stage. Here we imaged the dissociation process of bilayer NaCl islands on an Au (111) surface at the atomic scale using a low-temperature scanning tunneling microscope. We found that water molecules preferentially combined with Na+, and formed Na+ hydrates accompanied by Na+ vacancy defects. First-principles calculations revealed a small diffusion barrier of Na+ hydrates, which contributed to the migration of Na+ vacancy defects. The defect density of Na+ vacancies increased with extension of the water exposure time, which resulted in a reduction of binding energy of the NaCl system. Calculations revealed that when the number of Na+ vacancy defects in a local area reached 35, the binding energy of the NaCl system dropped to zero. Then the NaCl in this area would completely dissociate. This work aids understanding of the NaCl dissolution process at the atomic level, and offers some references for the application and design of insulating films.

Dissolution of Zinc Oxide Nanoparticles in the Presence of Slow Acid Generators.

We describe a preliminary investigation of the dissolution dynamics of zinc oxide nanoparticles in the presence of cyclic esters (δ-gluconolactone and propanesultone) as slow acid generators. The particles dissolution is monitored by means of turbidimetry and correlated with the evolution of pH over time. The results could be of interest for the design of chemically programmable colloidal systems.

Electrolyte Effects on the Stabilization of Prussian Blue Analogue Electrodes in Aqueous Sodium-Ion Batteries.

Aqueous sodium-ion batteries based on Prussian Blue Analogues (PBA) are considered as promising and scalable candidates for stationary energy storage systems, where longevity and cycling stability are assigned utmost importance to maintain economic viability. Although degradation due to active material dissolution is a common issue of battery electrodes, it is hardly observable directly due to a lack of in operando techniques, making it challenging to optimize the performance of electrodes. By operating Na2Ni[Fe(CN)6] and Na2Co[Fe(CN)6] model electrodes in a flow-cell setup connected to an inductively coupled plasma mass spectrometer, in this work, the dynamics of constituent transition-metal dissolution during the charge-discharge cycles was monitored in real time. At neutral pHs, the extraction of nickel and cobalt was found to drive the degradation process during charge-discharge cycles. It was also found that the nature of anions present in the electrolytes has a significant impact on the degradation rate, determining the order ClO4- > NO3- > Cl- > SO42- with decreasing stability from the perchlorate to sulfate electrolytes. It is proposed that the dissolution process is initiated by detrimental specific adsorption of anions during the electrode oxidation, therefore scaling with their respective chemisorption affinity. This study involves an entire comparison of the effectiveness of common stabilization strategies for PBAs under very fast (dis)charging conditions at 300C, emphasizing the superiority of highly concentrated NaClO4 with almost no capacity loss after 10 000 cycles for Na2Ni[Fe(CN)6].

Investigation of sorptive interaction between phosphonate inhibitor and barium sulfate for oilfield scale control

In both offshore deepwater and shale fields, a large amount of produced water will be generated during field operations. One consequence of significant produced water production from the field is mineral scale formation. Barium sulfate (barite) is one of the toughest scales to manage in oilfield. To combat scale issues, scale inhibitor has been widely adopted to inhibit scale deposition. Previous studies have confirmed that sorptive interactions between chemical inhibitor and scale particles play a vital role in scale prevention and control. Although extensive studies have been carried out on inhibitor-scale interaction, a comprehensive understanding of inhibition is yet available and the detailed sorptive interaction between inhibitor and mineral scale is not fully understood. In this study, experimental efforts have been made to explore the governing mechanism of sorptive behavior of a common phosphonate inhibitor onto the surface of barite particles. Adsorption and desorption experiments involving phosphonate and barite were carried out over a wide range of physiochemical conditions in a systematic manner. It shows that both adsorption and desorption of inhibitor to and from barite surfaces proceed rapidly. At a low phosphonate concentration, surface adsorption mechanism accounts for the interaction between phosphonate and barite. The release of phosphonate inhibitor from the barite surface is controlled by the dissolution dynamics of the formed Ca-phosphonate precipitate. This study is the first report of investigation of barite with phosphonate inhibitor with low and ultra-low concentrations as well as the inhibitory mechanism. The obtained results will improve our understanding of the interaction between phosphonate inhibitors and mineral scale. The findings can provide fundamental information that can benefit the inhibition performance and efficiency for barite scale control in oilfield operations.

Dissolution Dynamics and Accumulation of Ag Nanoparticles in a Microcosm Consisting of a Soil–Lettuce–Rhizosphere Bacterial Community

Assessment of chronic impact of metallic nanoparticles (NPs) in soil ecosystems is a necessity for ensuring safe and sustainable application. NPs affect plants and their associated microbial life, while the plants and their associated microbiota affect the NPs’ fate. Here, we measured the available Ag pool (determined as diethylenetriaminepentaacetic acid-extractable Ag) in AgNP-amended sandy loam soil (1, 10, and 50 mg Ag per kg of soil) over a period of 63 d with and without lettuce. The associated impacts on soil pH, Ag accumulation in lettuce, and the responses of the rhizosphere bacterial community were determined. We found that the addition of AgNPs significantly increased the soil pH from 7.70 to 7.87 after a short-term (7 d) incubation. Noteworthily, the extractability of Ag in AgNP-amended soil was concentration-dependent and changed over time because of their continuous dissolution and uptake by plants. Ag uptake and upward translocation in lettuce positively correlated with the extractable Ag content in soil. Furthermore, a long-term (63 d) exposure to 50 mg/kg of AgNPs altered the structure and composition of the rhizosphere bacterial community potentially by regulation of bacterial groups associated with element (e.g., N and S) cycling and stress tolerance. In conclusion, our results demonstrated that the dynamic dissolution of AgNPs in sandy loam soil plays an important role in influencing the overall Ag bioavailability of the NPs in plants. The enhanced effects of AgNPs on the alterations in the rhizosphere bacterial community highlight that the long time-resolved dynamics of NP exposure should be taken into consideration for accurate ecological risk assessment of NPs in the soil ecosystem.

Ingeniously Designed Yolk-Shell-Structured FeSe2@NDC Nanoboxes as an Excellent Long-Life and High-Rate Anode for Half/Full Na-Ion Batteries.

Thanks to their high conductivity and theoretical capacity, transition metal selenides have demanded significant research attention as prospective anodes for sodium-ion batteries. Nevertheless, their practical applications are hindered by finite cycle life and inferior rate performance because of large volume expansion, polyselenide dissolution, and sluggish dynamics. Herein, the nitrogen-doped carbon (NC)-coated FeSe2 nanoparticles encapsulated in NC nanoboxes (termed FeSe2@NDC NBs) are fabricated through the facile thermal selenization of polydopamine-wrapped Prussian blue precursors. In this composite, the existing nitrogen-doped dual carbon layer improves the intrinsic conductivity and structural integrity, while the unique porous yolk-shell architecture significantly mitigates the volume swelling during the sodium/desodium process. Moreover, the derived Fe-N-C bonds can effectively capture polyselenide, as well as promote Na+ transportation and good reversible conversion reaction. As expected, the FeSe2@NDC NBs deliver remarkable rate performance (374.9 mA h g-1 at 10.0 A g-1) and long-cycling stability (403.3 mA h g-1 over 2000 loops at 5.0 A g-1). When further coupled with a self-made Na3V2(PO4)3@C cathode in sodium-ion full cells, FeSe2@NDC NBs also exhibit considerably high and stable sodium-storage performance.

This review gives an overview of this research, focusing on (i) relationship formation, (ii) fertility, children and parenting and (iii) relationship dissolution.

Quantitative visual analysis of marine barite microcrystals: Insights into precipitation and dissolution dynamics

AbstractThe accumulation rate of authigenic barite (BaSO4) in marine sediments is a promising proxy for reconstructing marine export production, but many aspects of barite precipitation and dissolution in the water column remain unknown. Here, we collected, imaged, and quantitatively analyzed 5481 barite microcrystals in bottle casts from the Eastern Pacific water column to gain a better understanding of in situ barite dynamics. Barite crystal abundance increases rapidly between the surface and 500 m in depth and then declines to predominantly low abundances below ~ 1000 m. The falloff in barite abundance between the oxygen minimum zone (OMZ) and the ocean interior suggests 60% ± 20% loss of barite by dissolution, nearly all of which is complete by water depths of 1000 m. However, there are occasional samples, as deep as 1250 m, with unusually high barite abundance that may represent marine snow deposition events. We found that microcrystals associated with organic matter substrates were smaller and less solid than free crystals, which suggests ongoing barite precipitation toward larger, more regularly shaped microcrystals within organic matter aggregates. Trends in barite microcrystal size with depth suggest that organic matter aggregates also play a role in shielding barite microcrystals from dissolution. In addition, our extensive data set raises new questions regarding marine barite nucleation and spatial heterogeneity. By helping bridge the gap between hypothesized barite dynamics and in situ observations of barite microcrystals, this study advances our understanding of water column Ba processes and the utility of sediment barite as an export production proxy.

Usefulness of Thromboelastography for Perioperative Evaluation of Hemostatic Profile in Patients with Primary Brain Tumors Undergoing Surgery.

Context:Hemostatic abnormalities are more common in patients with brain tumors than systemic malignant diseases. Conventional coagulation tests (CCT) are poor assays for dynamic assessment of clot strength in whole blood. Thromboelastography (TEG) gives us detailed information on the dynamics of clot development, stabilization, and dissolution reflecting in vivo hemostasis. TEG can assess both thrombosis and fibrinolysis.Aims:This study aimed to investigate the temporal trends in hemostatic profile occurring during surgery for primary brain tumors, using a combination of TEG and CCT, and to assess perioperative blood component support.Subjects and Methods:A prospective, observational study was done on 40 patients with primary brain tumors larger than 4 cm in maximum diameter on computed tomography or magnetic resonance imaging. The tests (TEG and CCT [PT, INR, activated partial thromboplastin time, and platelet count]) were performed preoperatively (on the day of surgery), intraoperatively (2 h into surgery), and postoperatively (the day after surgery).Statistical Analysis:SPSS Version 21.0 statistical analysis software was used.Results:We found a universal trend toward hypercoagulability (persistent decrease in R-time, K-time and increase in MA, α-angle, Coagulation Index) in all the TEG parameters measured intraoperatively and postoperatively even though the values were within normal limits. Results of CCT had poor correlation with TEG parameters. The mean intraoperative blood loss was 737.7 ± 185.6 mL, for which PRBC was transfused in 17 patients, FFP in 13, but no platelet transfusion was done intraoperatively.Conclusions:We found a trend toward hypercoagulability in our study in intraoperative and postoperative period using TEG which was not evident on CCT. TEG was a useful diagnostic tool to identify coagulation abnormalities and to guide perioperative blood transfusion.

Investigation on the Hansen solubility parameter, solvent effect and thermodynamic analysis of indapamide dissolution and molecular dynamics simulation

In this work, the dissolution behavior of indapamide (IDP) in different solvents was researched. Solubility of IDP in methanol, ethanol, acetonitrile, 1-propanol, ethyl acetate, 2-propanol, 2-butanone, acetone, toluene and cyclohexane at series temperatures (278.15 K-318.15 K) was determined. The outcomes indicated that the solubility of IDP increased with increasing temperature. At a certain temperature, the mole solubility sequence of IDP was acetone > 2-butanone > methanol > ethanol > 1-propanol > acetonitrile > 2-propanol > ethyl acetate > toluene > cyclohexane. The Hansen solubility parameter (HSP) was used to evaluate ability of solvent to dissolve and explain the solubility behavior of IDP. Solvent effect was discussed by Kamlet and Taft linear solvation energy relationship (KAT-LSER) model, and the hydrogen bonds interactions (HBA) and nonspecific dipolarity/polarizability interactions had more advantageous impact on solubility of IDP. Moreover, molecular dynamics (MD) simulation was employed to construct the dissolving model and provide molecular level understanding the solute–solvent interaction in dissolution process of IDP. In addition, the experimental solubility data of IDP was correlated by Apelblat model, λh model, NRTL model and Wilson model. The applicability of these models were evaluated by Akaike Information Criterion analysis. The relative average deviation (RAD) and root-mean-square deviation (RMSD) values were no greater than 2.94% and 5.03 × 10−4, respectively. These four thermodynamic models were able to correlate the solubility data well and the Apelblat model was the best correlation model of these four models. Finally, the dissolution thermodynamic properties were obtained by van't Hoff analysis. The all positive values of thermodynamic properties indicated that the dissolution of IDP was an endothermic and entropy driven process.

Molecular dynamics of dissolution of a 36-chain cellulose Iβ microfibril at different temperatures above the critical pressure of water

The cellulose dissolution is an essential pretreatment process for the chemical conversion of lignocellulosic biomass into biofuels. Here, the dissolution of a 36-chain Iβ cellulose model with a hexagonal cross-section (M36HCS) in water is analyzed by Molecular Dynamics (MD) with CHARMM36/TIP3P (C36/TIP3P) force field using gradual heating at 25 MPa. Our simulations showed that the dissolution of M36HCS starts to occur between 560 K and 600 K, which agrees with experimental observations. In our system, conditions near the critical point of water reveal that translational and rotational entropies decrease, while the low hydration level increases vibrational entropy. This investigation theoretically shows that C36/TIP3P adequately reproduces the dissolution of M36HCS even in high-pressure water as corroborated in reactors.

Controlling: the composition of plasma-activated water by Cu ions

It is demonstrated that Cu ions can be used to control the ageing of plasma-activated liquids through the Fenton-type reaction, which acts as a competitor to the + H2O2 + H+ → products reaction, and thus moderates the recombination of ions. It is shown that the ageing dynamics is influenced by the type of Cu-ions source used, due to the different ion dissolution dynamics. Using CuNP-colloidal and copper acetate salt solutions, respectively, similar ageing dynamics can be achieved: the lifetime of can be increased to 104 min comparing to 102 min obtained in plasma-activated water, while the H2O2 concentration decreases to about half of its initial value. While the treated salt solutions contain the degradation products of the salt compounds, the CuNPs can be filtered out from the plasma-activated colloid (PAC). It is shown that filtration does not influence the concentration of active species, while the ageing of the filtrated PAC depends on the moment of filtration, which determines the concentration of dissolved Cu ions. Using copper foil, the dissolved Cu-ion concentration can be controlled by removing the foil during ageing, and in this way the lifetime of species and the H2O2 concentration can be adjusted. The effect has been validated in the case of two different plasma sources: a surface-wave microwave discharge and a kHz plasma jet, which produce PALs with different concentration ratio, which is the main governor of the ageing process.

Intermittent dynamics of bubble dissolution due to interfacial growth of fat crystals.

Foams are inherently unstable objects, that age and disappear over time. The main cause of foam aging is Ostwald ripening: smaller air bubbles within the foam empty their gas content into larger ones. One strategy to counter Ostwald ripening consists in creating armored bubbles, where solid particles adsorbed at the air/liquid interface prevent bubbles from shrinking below a given size. Here, we study the efficiency of coating air bubbles with fat crystals to prevent bubble dissolution. A monoglyceride, monostearin, is directly crystallized at the air/oil interface. Experiments on single bubbles in a microfluidic device show that the presence of monostearin fat crystals slows down dissolution, with an efficiency that depends on the crystal size. Bubble ripening in the presence of crystals exhibits intermittent dissolution dynamics, with phases of arrest, when crystals jam at the interface, followed by phases of dissolution, when monostearin crystals are ejected from the interface. In the end, crystals do not confer enough mechanical strength to the bubbles to prevent them from fully dissolving.

Three-generation households in the U.S.: The first exit after a child’s birth

Despite the increased prevalence of three-generation households in the U.S., there is still a limited understanding of the dynamics of dissolution of these households. Using event-history analysis and data drawn from the first five waves of the Fragile Families and Child Wellbeing Study and its restricted contextual data, this study describes how long mothers and their newborns spend in three-generation households after the child’s birth and whether this duration differs by race and ethnicity. Additionally, it examines the correlates of the first transition out and whether they differ by race and ethnicity. Results indicate that children and their mothers are more likely to experience the first exit between birth and age 1, and a formal test does not find significant differences by race and ethnicity. Several non-economic factors are positively associated with the exit out of three-generation households including a mother’s marital status and having a new partner; factors with a negative association include the number of children in the household and whether the focal child is a mother’s first kid. Finally, TANF or SNAP receipt and mothers’ employment are both positively associated with the first exit out of three-generation households. There are not significant differences in correlates of first exit by race and ethnicity. Implications and directions for future research are discussed.

The impact of ventilation patterns on calcite dissolution rates within karst conduits

Erosion rates in streams vary dramatically over time, as differences in streamflow and sediment load enhance or inhibit erosion processes. Within cave streams, and other bedrock channels incising soluble rocks, changes in water chemistry are an important factor in determining how erosion rates will vary in both time and space. Prior studies in surface streams, springs, and caves suggest that variation in dissolved CO2 is the strongest control on variation in calcite dissolution rates. However, the controls on CO2 variation remain poorly quantified. Limited data suggest that ventilation of karst systems can substantially influence dissolved CO2 within karst conduits. However, the interactions among cave ventilation, air–water CO2 exchange, and dissolution dynamics have not been studied in detail. In this study, three years of time series measurements of dissolved and gaseous CO2, cave airflow velocity, and specific conductance from Blowing Springs Cave, Arkansas, were analyzed and used to estimate continuous calcite dissolution rates and quantify the correlations between those rates and potential physical and chemical drivers. We find that chimney effect airflow creates temperature-driven switches in airflow direction, and that the resulting seasonal changes in airflow regulate both gaseous and dissolved CO2 within the cave. As in previous studies, partial pressure of CO2 (pCO2) is the strongest chemical control of dissolution rate variability. However, we also show that cave airflow direction, rather than streamflow, is the strongest physical driver of changes in dissolution rate, contrary to the typical situation in surface channel erosion where floods largely determine the timing and extent of geomorphic work. At the study site, chemical erosion is typically active in the summer, during periods of cave downdraft (airflow from upper to lower entrances), and inactive in the winter, during updraft (airflow from lower to upper entrances). Storms provide only minor perturbations to this overall pattern. We also find that airflow direction modulates dissolution rate variation during storms, with higher storm variability during updraft than during downdraft. Finally, we compare our results with the limited set of other studies that have examined dissolution rate variation within cave streams and draw an initial hypothesis that evolution of cave ventilation patterns strongly impacts how dissolution rate dynamics evolve over the lifetime of karst conduits.

Evaluation of the properties of daughter bubbles generated by inertial cavitation of preformed microbubbles

Inertial cavitation (IC) of the preformed microbubbles is being investigated for ultrasound imaging and therapeutic applications. However, microbubbles rupture during IC, creating smaller daughter bubbles (DBs), which may cause undesired bioeffects in the target region. Thus, it is important to determine the properties of DBs to achieve controllable cavitation activity for applications. In this study, we theoretically calculated the dissolution dynamics of sulfur hexafluoride bubbles. Then, we applied a 1-MHz single tone burst with different peak negative pressures (PNPs) and pulse lengths (PLs), and multiple 5-MHz tone bursts with fixed acoustic conditions to elicit IC of the preformed SonoVue microbubbles and scattering of DBs, respectively. After the IC and scattering signals were received by a 7.5-MHz transducer, time- and frequency-domain analysis was performed to obtain the IC dose and scattering intensity curve. The theoretical dissolution curves and measured scattering intensity curves were combined to determine the effect of the incident pulse parameters on the lifetime, mean radius and distribution range of DBs. Increased PNP reduced the lifetime and mean size of the DBs population and narrowed the size distribution. The proportion of small DBs (less than resonance size) increased from 36.83% to 85.98% with an increase in the PNP from 0.6 to 1.6 MPa. Moreover, increased PL caused a shift of the DB population to the smaller bubbles with shorter lifetime and narrower distribution. The proportion of small bubbles increased from 25.74% to 95.08% as the PL was increased from 5 to 100 µs. Finally, increased IC dose caused a smaller mean size, shorter lifetime and narrower distribution in the DB population. These results provide new insight into the relationship between the incident acoustic parameters and the properties of DBs, and a feasible strategy for achieving controllable cavitation activity in applications.

Dynamics of flow in albumin solution treated by low-temperature atmospheric pressure helium plasma jet

Dynamics of albumin agglomeration and dissolution induced by a helium plasma jet using the Schlieren visualization technique were demonstrated. The Schlieren technique enabled us to visualize the plasma-induced agglomeration of albumin on the albumin solution and dissolution from the agglomerate. Through the dissolution, a high-density albumin region moved downward, forming downward flows. During the plasma treatment, the downward flows were observed with a flow velocity of around 0.2 mm/s, while the flow velocity was 0.7 mm/s–0.9 mm/s without the plasma treatment. It was found that the plasma treatment decelerates the downward flows.

Dissolution and Shrinking of a Single Microbubble in Stationary Liquid with Surfactants

AbstractFor a variety of applications of microbubbles, it is necessary to clarify the dissolution dynamics and the lifetime of a microbubble. Although various models have been proposed, predicting the dissolution rate of a microbubble in a static fluid with a surfactant is still difficult. In this study, dissolution behavior was predicted with taking into account the mass transfer inhibition effect due to a surfactant at the bubble surface. The shrinking behavior of an oxygen microbubble was observed with several surfactants and the experimental results were in good agreement with model predictions.

Effects of Fe3+ on Dissolution Dynamics of Carbonate Rocks in a Shallow Burial Reservoir

Dissolution of carbonates in acidic fluids, which has attracted much research attention in recent years, is of great significance for the formation of high-quality reservoirs. The dissolution stage under low temperature and low pressure in shallow burial is one of the most important processes of reservoir dissolution and transformation. However, the dissolution dynamics of carbonate rocks in shallow burial and their formation have been controversial for a long time, and there are still disputes in the dissolution processes about how associated minerals and accessory minerals (e.g., pyrite) in carbonate reservoirs influence the formation of secondary pores. Additional metal ions in acidic fluids can change fluid properties and dissolution processes, and consequently affect reservoir quality. However, there are few laboratory studies done on the effect of associated minerals on the dissolution dynamics of carbonates. To clarify the specific impact of Fe-bearing associated minerals and Fe3+ on the dissolution of carbonates in shallow burial reservoirs, six samples of typical carbonate rocks in the Zigui area of Hubei Province, China were studied. The dissolution kinetics of carbonates in dilute hydrochloric acid and sulfuric acid solutions containing metal ions (Fe3+/Ca2+/Mn2+) at ambient temperature and pressure (T = 25 °C, P = 1 atm) were studied, by laboratory dissolution experiments combined with numerical simulations using PHREEQC. The results show that the Fe3+ is of great significance on the dissolution of carbonate rocks, while the influences of Ca2+ and Mn2+ are relatively weak. The dissolutions degrees of micritic limestone (ZG-L25), dolomitic limestone (ZG-L7) and dolomite (ZG-D9) were better than the other carbonates under the influence of metal ions (Fe3+/Ca2+/Mn2+) in acid solutions. Therefore, the dolomite reservoir of the Cambrian Qinjiamiao Formation, the dolomitic limestone reservoir of the Tianheban Formation and the limestone reservoir of the Triassic Daye Formation in the Zigui area are potential high-quality reservoirs. The carbonate reservoirs associated with Fe-bearing minerals were easier to dissolve and formed secondary pores under shallow burial. This process is beneficial to the formation of high-quality reservoirs. Moreover, the addition of Fe3+ into hydrochloric acid solution may be conducive to improving the reservoirs acidizing effect. Furthermore, the results gave innovative results from multiple perspectives of geo-material science and computational geosciences, which may provide new avenues for in-depth study of carbonate dissolution in shallow burial based on water–rock reaction, chemical dissolution, computational simulation, and geological background.
