Lithium (Li) and strontium (Sr) are two economically relevant chemical elements whose oceanic biogeochemical cycles are not fully constrained. In particular, how they disperse and behave from hydrothermal sources into the water column is understudied while hydrothermal systems on the global mid-ocean ridge network (~67,000 km) represent one of the...

The mixing zone between high temperature hydrothermal fluids and seawater produces redox gradients, promoting the development of unique ecosystems based on chemotrophy. The structure of microbial communities depends on their environment, which can vary according to space and time. Hydrothermal circulation within the oceanic crust determines the che...

A collection of 34 pore fluids from young clay-rich sedimentary piles of the Shikoku basin on the Philippine oceanic plate at the front of the Nankai subduction zone, southeast of Japan, were analyzed for their chloride content and chlorine stable isotope composition (³⁵Cl and ³⁷Cl, reported as δ³⁷Cl). These pore fluids are samples from IODP Sites...

While hydrothermal vents are now thought to be a major source of dissolved iron to the oceans, they have always been considered to be a sink for the dissolved rare-earth elements (DREEs). However, true dissolved REE observations in hydrothermal plumes are still lacking. Here we report for the first time the DREE concentrations and neodymium isotopi...

The evolution of the seawater oxygen isotopic composition (δ18O) through geological time remains controversial. Yet, the past δ18Oseawater is key to assess past seawater temperatures, providing insights into past climate change and life evolution. Here we provide a new and unprecedentedly precise δ18O value of −1.33 ± 0.98‰ for the Neoproterozoic b...
Article
Information about diagenetic processes and temperatures during burial of sediments entering the subduction zone is important for understanding changes in physical properties and seismic behavior during deformation. The geochemistry of authigenic carbonates from accretionary prisms can serve as proxies for conditions during carbonate cementation and...

Large-offset detachment faults are widespread along the slow-spreading Mid-Atlantic Ridge (MAR), exhume ultramafic rocks, and host a great diversity of hydrothermal systems. During the ODEMAR'13 cruise, the fully developed 13º20'N and 13º30'N oceanic core complexes (OCC) along MAR were investigated to constrain the tectonic, hydrothermal and magmat...

Article
We present data from sediment cores collected from IODP Site C0012 in the Shikoku Basin. Our site lies at the Nankai Trough, just prior to subduction of the 19 Ma Philippine Sea plate. Our data indicate that the sedimentary package is undergoing multiple routes of electron transport and that these differing pathways for oxidant supply generate a co...

The Nankai Trough Seismogenic Zone Experiment (IODP) is aimed at unraveling hydrologic processes at subduction megathrusts and in situ properties to understand the fault zone behavior during earthquake nucleation and rupture propagation. At different sites, the characterization at small scales of the sediments traces the reactions with fluids, eith...

The fluid-solid reactions within the different layers of the oceanic crust control, for main part, the oceanic budget and chemical balance; they are linked to large heat and chemical transfers. As by-products, clay minerals and paragenetic phases (zeolites, oxides…) are sensitive to conditions of reactions and relate major geodynamic and oceanograp...

The western flank of the Great Bahama Bank, drilled during ODP Leg 166 at seven sites, represents a prograding carbonate sequence from late Oligocene to Holocene [Eberli et al., Proc. ODP Init. Reports 166 (1997)]. The signatures of the detrital input and of diagenetic alteration are evident in clay enriched intervals from the most distal Sites 100...

Uplifted serpentinized periddotites of Galicia Bank (NE Atlantic )were exposed to halmyrolysis since late Albian times and transformed into palygorskite and smectite. From thermodynamic modelling we deduce that palygorskite is an alteration product of serpentinite at common sea-floor conditions. The observed prevalence of palygorskite over semctite...

Based on porewater chemistry observations at Integrated Ocean Drilling Program (IODP) Sites C0011 (on the flank of Kashinosaki Knoll) and C0012 (near the crest of Kashinosaki Knoll), we interpret two independent flow systems within the input sediments to the Nankai subduction zone. We integrate lithology data and laboratory-constrained permeability...

... This cell abundance, noticeably in the upper range of sediments worldwide (typically of 10 6 -10 9 cells/cm 3 ), was also nearly as high as that of the sea floor at this site. Moreover, the lower part of the dark gouge in the megasplay fault drilled at site C0004 was also enriched in authigenic pyrite (Destrigneville et al., 2013), which makes diagenetic reactions in the megasplay very similar to those found in the tiny deformation bands studied here. Such an analogy strongly suggests that temperature rise is not the only factor capable of explaining the observed anomalies in the megasplay, and that many mineral reactions in the principal slip zone might be biologically mediated rather than thermally activated. ...
... Concentration in major elements Ca, Mg, Na were compiled from previous publications: Srivastava et al. (1987b,c,d), Peirce et al. (1989b,c), Davis et al. (1997b,c), Saito (2010a,b) and Henry et al. (2012a,b). The d 18 O values of the pore fluids were compiled from Zachos and Cederberg (1989), Lawrence (1991), Mottl et al. (2000), Mora (2005), Komor and Mottl (2006) and Destrigneville et al. (2016) using the CO 2 -H 2 O equilibration method of Epstein and Mayeda (1953). Precision is better than 0.1‰. ...
... Lava interacting with hydrothermal circulation cells produces extreme changes in water-rock reactions and the nature and degree of phase separation. These events also provide nutrients and energy to microbial populations 113 , alter macrofaunal communities and produce large deep-sea hydrothermal plumes in the water column 114 . ...
... where [Cl -] is generally higher than 10 mM. Ion filtration could generate 37 Cl-depletion in chlorides of pore fluid forced through clay membranes as proposed by Agrinier et al. (2019Agrinier et al. ( , 2021. This has been suggested as an explanation for the strong 37 Cl-depletions observed in the chlorides of the oceanic clayrich young sediment pore fluids. ...
... Notably, we omit measurements of [Nd]d > 100 pmol kg -1 from the model data comparison because they represent very localised signals which we do not attempt to resolve. These include extreme surface 515 concentrations present in restricted basins such as fjords, the Baltic Sea and the Gulf of Alaska (Chen et al., 2013;Haley et al., 2014), or input from hydrothermal activity (Chavagnac et al., 2018), which is not believed to govern global marine Nd distributions due to the immediate removal of hydrothermal Nd at the vent site (Goldstein and O'Nions, 1981). The location and spatial distribution of all observational records used in this study are shown in Fig. 8, and full details of the seawater compilation including a full list of all the references for the data sources are provided in Supplementary Information: Table 520 S4. with only 10% and 11% of measurements at depths below 3,000 m respectively. ...
... Some studies suggest that the seawater isotopic composition has remained unchanged (e.g. Henkes et al., 2018) while others follow the secular trend idea of the Veizer hypothesis (Veizer and Prokoph, 2015) of a gradual enrichment of the 18 O isotope (e.g., Galili et al., 2019;Hodel et al., 2018;Defliese, 2020). ...
... Tectonic and hydrothermal related processes may leave an imprint in the exhumed serpentinized rocks exposed at the seafloor and in first overlying sediments 5,6 . The further post-exhumation interaction between low-temperature seawater-derived fluid and serpentinite, that results in authigenesis of specific phases such as carbonates, silicates and oxides, extends the chemical transfers and may impact the oceanic mass budget 6,7 . The specific signature derived from alteration of exhumed mantle rocks may be recorded in the first sedimentary deposits and could be a good proxy for the identification and understanding of such processes in ancient analogue domains. ...
... However, such high pore water alkalinity anomaly is not commonly observed despite the prevalence of ongoing silicate weathering in anoxic sediments because any enrichment in alkalinity resulting from silicate weathering is likely to be masked by precipitation of authigenic phases. This inference is supported by previous studies that demonstrated the occurrence of carbonate nodules characterized by an enrichment in 13 C Teichert et al., 2014;Sample et al., 2017;Phillips et al., 2018;Loyd and Smirnoff, 2022) and a strontium isotopic composition distinct from coeval seawater values . Our model results also indicate that a Ca sink in authigenic carbonate is required to fit the observations (Fig. S2). ...
... Biologically mediated alteration of volcanic glasses was observed in deep-seated subsurface sediment samples and could account for up to 75% of their total alteration (Furnes and Tumyr, 1999;Staudigel et al., 2008). VA alteration, in turn, could serve to sustain subsurface microbial activity by releasing metals like Fe (III) and Mn (IV) that are utilized as electron acceptors for microbe-mediated redox reactions (Torres et al., 2015;Luo et al., 2020a). Furthermore, silica cement resulting from volcanic glass alteration is thought to modify the physical properties of the sediment column and affect deformation behavior as sediments are subducted or incorporated into the accretionary wedge (e.g., White et al., 2011). ...
... Studying element transfers related to serpentinization of abyssal peridotites is however challenging because of the nonuniqueness of peridotite protolith, the common lack of primary mineral relics due to the advanced stages of serpentinization of oceanic peridotites, the multiple stages of serpentinization affecting the peridotites, and the low-temperature post-serpentinization processes. Indeed, low-temperature alteration processes can occur secondary to serpentinization, transforming the serpentine minerals to clays and iron (oxyhydr)oxides, and causing gains and losses in several chemical elements (e.g., Al, Fe, Mg; Caillaud et al., 2006Caillaud et al., , 2009Destrigneville et al., 1998;Karpoff et al., 1989Karpoff et al., , 2017Snow and Dick, 1995;Venturelli et al., 1997). ...
