Summary: In hyperalkaline fluids involved in low-temperature serpentinization reactions, methane is dominantly produced by microbial activity, including methanogens and potentially abiotic sources. Microbial methane production occurs under varying degrees of C limitation, and there is evidence of another source of methane in fluid inclusions.

Summary: An innovative approach was used to process serpentinite samples consisting of different serpentine minerals. The samples were kept in a quiescent state for varying periods of time in a hydrochloric acid solution. The study found that serpentinites with chrysotile and lizardite minerals had a higher degree of magnesium extraction compared to those with predominantly antigorite mineral. Additionally, a quiescence period of 30 minutes was found to be sufficient for recovering up to 97% of total magnesium in serpentinites with chrysotile and lizardite minerals. This study emphasizes the importance of identifying serpentine polymorphs in achieving higher magnesium yields under mildly acidic conditions.

Summary: This study provides a comprehensive investigation into the characteristics, scale dependence, and potential implications of nanoporosity in lizardite-dominated serpentinites. Through imaging techniques and modeling, it reveals the nanoporous nature of serpentinites with pore sizes predominantly less than 100 nm. The study suggests that the irregular pore shapes align with the crystal form of serpentine minerals, and the nanoporosity results from various processes such as stochastic growth and low-temperature alteration.

Summary: Ni isotope fractionation in carbonate-rich ultramafic environments can be influenced by iron oxide and carbonate precipitation, leading to differences in isotopic signatures between active and inactive serpentinization sites. The initial strong fractionation between fluids and solids in the active system may diminish over time due to aging of the precipitates.

Summary: Chromium isotopes are powerful proxies for Earth's redox cycling, with shifts in isotope ratios indicating complex physicochemical processes. Stichtite formation involves intense metal mobility, and the Cr isotope fractionation reflects the interplay of various processes in critical zones. The presence of REY in both stichtites and serpentinites suggests a chemically similar fluid source, indicating water-rock interaction and reducing conditions during stichtite formation.

Summary: Hydration and carbonation reactions within the Earth can cause an increase in solid volume, leading to stress and rock fracture. Experimental evidence shows that under confining pressure, these reactions can significantly enhance permeability. The enhancement is due to fracturing of the reacting materials, while a decrease in permeability is caused by pore clogging.

Summary: Fluid-rock interaction in ultramafic rocks plays a significant role in shaping the chemical and isotopic composition of the oceanic lithosphere. The study of serpentinites and ophicalcites in Italy's Northern Apennine ophiolite reveals a complex history of interactions, including seawater circulation, Si-metasomatism, and carbonation. These interactions likely have implications for geochemical cycles and subduction zone processes.

Summary: Collocated crystal sizes and mineral identities are important for understanding geological relationships. Previous Mars rovers were unable to clearly determine these properties. However, the PIXL instrument on the Perseverance rover has shown that diffracted and fluoresced x-rays can provide information about crystalline domains in minerals. Analysis of rocks from the Seitah formation in Jezero crater indicates that they were originally coarsely crystalline igneous phases, with olivine grains partially dissolved and filled with secondary silicate, carbonate, sulfate, and chloride/oxychlorine minerals.

Summary: Serpentinization of ultramafic rocks is crucial for plate tectonics and carbon sequestration. Changes in physical properties of rocks during serpentinization and carbonation can be detected using geophysical surveys, providing insight into rock reactivity without extensive sample characterization. Further research is needed to understand the role of remanence in applying models to geophysical data for prospecting the most reactive ultramafic rocks for carbon sequestration.

Summary: Serpentinization is an important process in the deep sea that affects rock rheology, global fluid circulation, and microbiological activity. This study investigated the initial stage of olivine dissolution and serpentine precipitation and found that the relationship between the kinetics of serpentine precipitation and olivine dissolution varies with temperature and time.

Summary: The study found that the listvenite series in Oman have compositions similar to basal peridotites and are enriched in fluid mobile elements. This suggests that peridotite carbonation may play a significant role in the trapping and releasing of carbon, water, and FME along convergent margins.

Summary: The study focused on the petrology, mineralogy, and geochemistry of hydrothermally altered peridotites from the North-Western Pyrenean belt, revealing different degrees of serpentinization and reaction paths in the cooling process. The formation of magnetite in these samples was found to be influenced by fluid composition rather than solely by temperature, leading to variations in serpentinization pathways within and among different massifs.

Summary: Sedimentary pyrite is an important geological archive, but it can be altered by diagenetic and hydrothermal processes. This study successfully trained machine learning algorithms to distinguish pyrite origins using trace element data. The approach was validated and applied to identify the origins of pyrite in two sedimentary successions in South China.
