“…Different bacterial facies can induce opposite processes depending on the environmental conditions (Dupraz et al, 2009; Dupraz & Visscher, 2005; Fernández‐Remolar et al, 2012). For instance, as anaerobic methane oxidation (AMO) can induce the precipitation of carbonates (Guo, Wen, Li, et al, 2023; Guo, Wen, & Sánchez‐Román, 2023; Michaelis et al, 2002), aerobic methane oxidation favours carbonate dissolution by producing CO 2 and acidifying the local pH (Krause et al, 2014). These pathways are performed by different microorganisms (e.g., Archaea of the cluster ANME‐1/2 and bacteria like Methylosinus trichosporium , respectively), and the outcome in terms of carbonate alteration depends on their coupling and balance, as well as on their synergies with other components of the microbial consortia (e.g., sulfate reducers as Desulfosarcina/Desulfococcus spp.…”

“…Such a rational approach has been used to discover ammonia oxidation metabolisms alternative to aerobic oxidation (Strous et al, 2002; van de Leemput et al, 2011) and, in the field of carbonate dissolution/precipitation, to identify cyanobacteria microborers (Garcia‐Pichel, 2006; Garcia‐Pichel et al, 2010). Other studies have reviewed the current knowledge of metabolic processes that may be implicated in carbonate turnover, including dissimilatory sulfate reduction, AMO and ureolysis (Dupraz et al, 2009; Guo, Wen, Li, et al, 2023; Guo, Wen, & Sánchez‐Román, 2023; Visscher & Stolz, 2005). Fewer efforts have been devoted to exploring the role of the overall microbial community in the micritization process, except in the microbialite community, where multiple taxonomic and even functional studies of the microbial diversity involved in carbonate precipitation/dissolution have been performed (Ruvindy et al, 2016; Saghaï et al, 2016).…”

Micritization is an early diagenetic process that gradually alters primary carbonate sediment grains through cycles of dissolution and reprecipitation of microcrystalline calcite (micrite). Typically observed in modern shallow marine environments, micritic textures have been recognized as a vital component of storage and flow in hydrocarbon reservoirs, attracting scientific and economic interests. Due to their endolithic activity and the ability to promote nucleation and reprecipitation of carbonate crystals, microorganisms have progressively been shown to be key players in micritization, placing this process at the boundary between the geological and biological realms. However, published research is mainly based on geological and geochemical perspectives, overlooking the biological and ecological complexity of microbial communities of micritized sediments. In this paper, we summarize the state‐of‐the‐art and research gaps in micritization from a microbial ecology perspective. Since a growing body of literature successfully applies in vitro and in situ ‘fishing’ strategies to unveil elusive microorganisms and expand our knowledge of microbial diversity, we encourage their application to the study of micritization. By employing these strategies in micritization research, we advocate promoting an interdisciplinary approach/perspective to identify and understand the overlooked/neglected microbial players and key pathways governing this phenomenon and their ecology/dynamics, reshaping our comprehension of this process.

Ensuring a stable and cost-effective energy supply is a major challenge for the International Energy Agency (IEA). Additionally, the effectiveness of vermiculite and dolomite in mitigating the adverse effects of diesel oil, a petroleum-derived product, on plant growth and development, and on the biochemical activity of the soil, were assessed. Therefore, an attempt was made in the study to determine the energy properties of Zea mays, which is suitable for cultivation in contaminated areas. For these purposes, several parameters were analyzed in its biomass, including calorific value (Q), heating value (Hv), energy yield (Yep), ash content, and the presence of carbon (C), hydrogen (H), sulfur (S), nitrogen (N), and oxygen (O). Biochemical activity was measured through the evaluation of soil enzymes serving as indicators for the carbon (dehydrogenases, catalase, β-glucosidase), nitrogen (urease), sulfur (arylsulfatase), and phosphorus (acid and alkaline phosphatase) cycles. The plant greenness index was also determined. It has been demonstrated that diesel oil does not alter the calorific value of Zea mays biomass but significantly reduces the biomass quantity and destabilizes the biochemical properties of the soil. Zea mays contained an average of 6.84% ash, 49.88% C, 5.65% H, 0.17% S, 2.90% N, and 34.57% O. The calorific value of Zea mays ranged from 15.02 to 15.54 MJ kg−1 d.m. of plants, and the heating value ranged from 18.25 to 19.21 MJ kg−1 d.m. of plants. The biomass obtained from contaminated soil is recommended for energy purposes. The sorbents used—vermiculite and dolomite—proved to be less effective in the remediation of soil contaminated with diesel oil.

“…In saline and alkaline lakes, authigenic minerals, such as Mg-rich clay minerals and Mg-rich evaporites, will compete for Mg 2+ with dolomite [79,80]. In non-alkaline saline lakes, authigenic Mg minerals like Mg-rich clay and Mg-rich evaporites either precipitate to a minimal extent or do not deposit [21]. During the deposition of the Qianjiang Formation, the basin was characterized as a nonalkaline salt lake [21,81], leading to the minimal or negligible development of authigenic clay minerals, and the lack of Mg in evaporites can also support this (Table S2).…”

“…As mentioned above, previous studies on magnesium isotopes in dolomite have primarily focused on marine dolomite, with lacustrine environments, especially in saline lake basins, receiving relatively limited scrutiny. Recently, there has been a gradual increase in geochemical research focusing on the carbonate constituents in lacustrine carbonate [18][19][20][21]. For instance, carbon and oxygen isotopes in carbonates have been employed to reconstruct ancient environments [22], while Mg isotopes of halite serve as a sensitive indicator for drying and recharging events in terrestrial saline lakes [23].…”

The investigation of magnesium (Mg) isotopes in dolomite has mainly focused on marine dolomite environments, leaving a significant gap in the understanding of their dynamics within lacustrine settings, especially in saline lake basins. In this study, a total of 16 sediment core samples from Well BX-7 in the Qianjiang Depression were sequentially selected for scanning electron microscope observation, whole-rock analysis for major and minor elements, and isotopic measurements including δ18Ocarb, δ13Ccarb, δ26Mgdol, and δ26MgSi. In addition, two intact cores were subjected to detailed analysis on the centimeter scale. Sedimentation models were established to elucidate dolomite formation under contrasting climatic conditions, specifically humid climates with a significant riverine Mg input versus relatively dry conditions with a lower Mg input. Furthermore, a quantitative model was developed to assess the magnesium flux and isotopic mass balance within lacustrine systems, simulating the magnesium isotope variations in lake water under different climatic scenarios. The dolomite sample data at a smaller scale (sampling interval ≈ 3~5 mm) demonstrate a consistent trend with the established model, providing additional confirmation of its reliability. Dolomite precipitated under humid climatic conditions exhibits a lower and relatively stable δ26Mgdol, lower δ18O, and higher CIA, indicating higher river inputs and relatively stable Mg isotope values of lake water controlled by river input. Nevertheless, dolomite formed under relatively dry climatic conditions shows a relatively high δ26Mgdol, higher δ18O, and lower CIA, suggesting reduced river inputs and weathering intensity, as well as relatively high magnesium isotope values of the lake water controlled by dolomite precipitation. This study contributes to the understanding of magnesium isotopes in lacustrine dolomite systems.
