will govern the spatial extent of serpentinisation and FME enrichment, ultimately amplifying heterogeneities 2 FME enrichments from serpentinisation are largely retained and reincorporated into the convecting mantle, providing potential fractionation mechanisms for U-Th systematics (HIMU) and enriched mantle (EM) sources 2 FMEs such as As, Sb, W and Bi, which are rarely quantified, can provide

The serpentinites are characterized by high concentration of fluid-mobile elements (FME: As, Sb, B, Li, and U) compared to ophiolitic or abyssal serpentinites. The Pb isotopic compositions of serpentinites show influence of the subducted Indian continental lithosphere. Trace element concentrations of antigorite determined in situ with Laser Ablation High Resolution Inductively Coupled Mass Spectrometer (LA-HR-ICP-MS) show high contents of FME including Pb, in contrast to the spatially associated iron oxides. Rare earth elements (REE) and compatible elements, such as Sc and Co, remained immobile during the hydration, allowing the identification of the primary minerals (olivine or orthopyroxene) from which serpentine formed. Serpentinized olivine displays higher Sb and As concentrations (up to 1000 × PM) than serpentinized orthopyroxenes that are enriched in Pb, Cs and Li (2 to up to 10 × PM). We propose that the observed FME distribution in two types of serpentine reflect the differential incorporation of FME during the downward movement of the serpentinite along the subduction plane. At temperature lower than 400°C, at shallow depths, olivine is preferentially serpentinized and incorporates elements that are fluid soluble at low temperatures, such as Sb and As. Above 400°C, orthopyroxene is hydrated and incorporates Pb, Cs, Li and possibly Ba. Boron and U are incorporated in both types of serpentine suggesting that they are released from slabs at temperatures around 300-400°C. The serpentine acts as a sink for water, but also for FME and transports them to deeper and hotter levels in the mantle, down to the isotherm 600-650°C where dehydration occurs.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"In situ characterization of serpentinites from forearc mantle wedges: Timing of serpentinization and behavior of fluid-mobile elements in subduction zones","attachmentId":45914772,"attachmentType":"pdf","work_url":"https://www.academia.edu/12819286/In_situ_characterization_of_serpentinites_from_forearc_mantle_wedges_Timing_of_serpentinization_and_behavior_of_fluid_mobile_elements_in_subduction_zones","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/12819286/In_situ_characterization_of_serpentinites_from_forearc_mantle_wedges_Timing_of_serpentinization_and_behavior_of_fluid_mobile_elements_in_subduction_zones"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="1" data-entity-id="2427872" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/2427872/Constraining_the_rate_and_extent_of_mantle_serpentinization_from_seismic_and_petrological_data_implications_for_chemosynthesis_and_tectonic_processes">Constraining the rate and extent of mantle serpentinization from seismic and petrological data: implications for chemosynthesis and tectonic processes</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="102248" href="https://uppsala.academia.edu/HeminKoyi">Hemin Koyi</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Geofluids, 2005</p><p class="ds-related-work--abstract ds2-5-body-sm">We used seismic velocity as a proxy for serpentinization of the mantle, which occurred beneath thinned but laterally continuous continental crust during continental break up, prior to opening of the Atlantic Ocean. The serpentinized sub-continental mantle is now exhumed, beneath the Iberia Abyssal Plain and was accessed by scientific drilling on Ocean Drilling Program legs 149 and 173. Chromatographic modelling of kinetically limited transport of the serpentinization front yields a front displacement of 2197 ± 89 m, a time-integrated fluid flux of 1098 ± 45 m3 m−2 and a Damköhler number of 6.0 ± 0.2. Whether either surface reaction or chemical transport limit the rate of reaction, we calculate timescales for serpentinization of approximately 105–106 years. This yields time-average fluid flux rates for H2O, entering and reacting with the mantle, of 60–600 mol m−2 a−1 and for CH4, produced as a by-product of oxidation of Fe++ to magnetite and exiting the mantle, of 0.55–5.5 mol m−2 a−1. This equates to a CH4-flux of 0.18–1.8 Tg a−1 for coeval serpentinization of the mantle that was exhumed west of Iberia. This represents 0.03–0.3% of the present-day annual CH4-flux from all sources and a higher fraction of pre-anthropogenic (lower) CH4 levels. CH4 released by serpentinization at or beneath the seafloor could provide substrate for biological chemosynthesis and/or promote gas-hydrate formation. Finally, noting its volumetric extent and rapidity (<106 years), we interpret serpentinization to be a reckonable component of tectonic processes, contributing both diapiric and expansional forces and helping to ‘lubricate’ extensional processes. Given its anisotropic permeability, actively deforming serpentinite might impede melt migration which may be of interest, given the apparent lack of melt in some rifted margins.</p><div

class="ds-related-work--abstract ds2-5-body-sm">In the Mariana subduction system, active serpentinite mud volcanoes are associated with the subduction of the Pacific plate beneath the Philippine plate in a non-accretionary convergent plate margin. This location offers a unique opportunity to study the subduction zone interface with little crustal contamination. The systematics of fluid-mobile trace elements (FME) (As, Cs, Rb, Sb, Tl, Pb, and Sr) in erupted serpentinite muds and entrained serpentinized ultramafic and mafic clasts can place constraints on the release of slab-derived fluids from the downgoing plate, and ultimately the pressure/temperature (P/T C°) conditions at which these fluids are mobilized. The samples analyzed in this study were recovered during International Ocean Discovery Program (IODP) Expedition 366, Mariana Convergent Margin and South Chamorro Seamount, and expand on existing data from Ocean Drilling Program (ODP) Legs 125 and 195 (Conical and South Chamorro Seamounts, respectively). Samples included ultramafic muds and clasts from the shallow subduction channel as well as mafic clasts and carbonates from subducted Pacific seamounts. Key findings of this study are that: (1) releases of FME from the subducting plate enrich the relatively depleted overlying mantle wedge, (2) elements with an affinity to be fluid-mobile appear to be enriched in distinct patterns, with As, Cs, and Rb increasing and Sr and, to a lesser extent, Pb decreasing with increasing depth-toslab, possibly indicating an enrichment source from the downgoing plate, vi (3) concentrations of FME in serpentinites vary with depth-to-subducting slab due to P/T C° conditions, and may be used as a tracer for dehydration of the subducting slab, (4) precipitation of minerals (aragonite, brucite, gypsum) strongly controls Ca, Mg, and S, respectively, and thus likely influence some FME concentrations when present, (5) pH changes with the introduction of seawater near the seafloor alter fluid-mobile element concentrations deposited into shallow serpentine muds, altering the pore fluid signature found within the serpentinized muds, and (6) progressive dehydration of the slab with increasing P/T C° conditions occurs as a result of at least two separate diagenetic regimes, opal dehydration and the conversion of smectite to illite in shallow-sourced seamounts, and the breakdown of clays at deeper-sourced seamounts.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Fluid-mobile Trace Element Variability of Serpentinites and Entrained Crustal Rocks across the Mariana Forearc System","attachmentId":79203281,"attachmentType":"pdf","work_url":"https://www.academia.edu/68892580/Fluid_mobile_Trace_Element_Variability_of_Serpentinites_and_Entrained_Crustal_Rocks_across_the_Mariana_Forearc_System","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/68892580/Fluid_mobile_Trace_Element_Variability_of_Serpentinites_and_Entrained_Crustal_Rocks_across_the_Mariana_Forearc_System"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="5" data-entity-id="14386777" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/14386777/Possible_density_segregation_of_subducted_oceanic_lithosphere_along_a_weak_serpentinite_layer_and_implications_for_compositional_stratification_of_the_Earths_mantle">Possible density segregation of subducted oceanic lithosphere along a weak serpentinite layer and implications for compositional stratification of the Earth's mantle</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="33330337" href="https://independent.academia.edu/CintyLee">Cin-ty Lee</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2007</p><p class="ds-related-work--abstract ds2-5-body-sm">There is growing evidence that the top part of the oceanic mantle is pervasively serpentinized prior to subduction. Because the interior of a subducting slab heats up slowly, the serpentinized layer can be preserved for tens of Myr, thereby forming a weak zone that allows for mechanical decoupling between the oceanic crust and underlying lithospheric mantle. Once the crust is eclogitized, a shear stress would be induced by a compositionally-driven buoyancy difference between the crust and the lithospheric mantle. By simple force balance, we show that the downward slip velocity of the crust relative to the lithospheric mantle is similar to subduction velocities themselves; hence, conditions necessary for segregation of eclogitized crust from lithospheric mantle are generally met well before the slab approaches the lower mantle. The segregated components are predicted to journey to different resting grounds. Depleted lithospheric mantle, being slightly less dense than the ambient mantle, would eventually rise upward and congregate in the upper mantle while eclogitic crust would settle in a neutrally buoyant state near the bottom of the transition zone or at the base of the lower mantle. We speculate that this process gradually leads to the irreversible compositional stratification of the Earth's mantle.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Possible density segregation of subducted oceanic lithosphere along a weak serpentinite layer and implications for compositional stratification of the Earth's mantle","attachmentId":44254198,"attachmentType":"pdf","work_url":"https://www.academia.edu/14386777/Possible_density_segregation_of_subducted_oceanic_lithosphere_along_a_weak_serpentinite_layer_and_implications_for_compositional_stratification_of_the_Earths_mantle","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/14386777/Possible_density_segregation_of_subducted_oceanic_lithosphere_along_a_weak_serpentinite_layer_and_implications_for_compositional_stratification_of_the_Earths_mantle"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="6" data-entity-id="2640374" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/2640374/Subduction_zone_fluxes_of_halogens_and_noble_gases_in_seafloor_and_forearc_serpentinites">Subduction zone fluxes of halogens and noble gases in seafloor and forearc serpentinites</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="1976705" href="https://uq.academia.edu/MarkAKendrick">Mark A Kendrick</a></div><p class="ds-related-work--abstract ds2-5-body-sm">Serpentinites form by hydration of ultramafic lithologies in a range of seafloor and shallow subduction zone settings. Serpentinites are recognised as major reservoirs of fluid mobile elements and H2O in subducting oceanic lithosphere, and together with forearc serpentinites formed in the mantle wedge, provide critical information about shallow-level volatile fluxes during subduction. The current study provides new Cl, as well as the first comprehensive Br, I and noble gas analyses reported for seafloor and forearc chrysotile–lizardite serpentinites. The samples were recovered from IODP drilling campaigns of mid-ocean ridge, passive margin and forearc settings (n=17), and ophiolites in the Italian Alps and Apennines (n=10). The aims of this study were to determine the compositional variability of noble gases and halogens in serpentinites entering subduction zones and evaluate the efficiency of gas loss during the early stages of serpentinite subduction.The chrysotile–lizardite serpentinites and serpentised peridotites contain 43–2300 ppm Cl and 3×10−13–2×10−11 mol g−136Ar, with the concentrations of these elements broadly related to the estimated degree of serpentinisation. The serpentinites have extremely variable Br/Cl and I/Cl ratios with many samples preserving compositions similar to organic-rich sedimentary marine pore fluids. Serpentinites from the Marianas Forearc have very high I concentrations of up to 45 ppm I and I/Cl ratios of ∼14,000 times the seawater value that is even higher than the maximum I/Cl enrichment observed in sedimentary marine pore fluids. The serpentinites have 130Xe/36Ar and 84Kr/36Ar ratios that are mostly close to or above seawater values, and 20Ne/36Ar ratios that range from seawater to lower values. The serpentinites contain <10–270 ppm K and, irrespective of age (0 Ma to ∼160 Ma), are characterised by 40Ar/36Ar ratios of 300–340 that are slightly higher than the seawater value of 296, thus indicating the presence of minor excess 40Ar*. Three of six serpentinites analysed for helium also have measurable excess 4He contents that cannot be explained by in situ production. The data show that serpentinites trap noble gases and halogens that originate from seawater, organic matter and diverse crustal lithologies.Combined with previous analyses of metamorphosed serpentinites, the new data suggest that approximately 60–70% of the 36Ar entering subduction zones in serpentinites is lost from chrysotile and/or antigorite and could potentially escape through the forearc. An additional, ∼20–30% of the 36Ar entering subduction zones in serpentinites is lost during antigorite breakdown and may be cycled through the arc or back-arc, and ∼1–10% of the 36Ar entering subduction zones in serpentinites may be subducted into the deeper mantle. The data demonstrate decoupling of noble gases, halogens and water during subduction and suggest that subduction-zone fluid fluxes can produce especially high concentrations of noble gases and iodine in newly formed forearc serpentinites. The distinctive I/Cl enrichment of forearc serpentinites suggest that halogen abundance ratios provide a plausible means for inferring the geotectonic setting of serpentinisation in ophiolite samples. The exceptional Cl, Br, I and noble gas concentrations of serpentinites, the potential subduction of the forearc serpentinites and the stability of serpentine minerals to mantle depths of >200 km, imply that serpentinites could dominate the deep recycling budgets of both the heavy halogens and atmospheric noble gases.► The first Cl, Br, I, He, Ne, Ar, Kr and Xe data for chrysotile–lizardite serpentinites. ► Samples of serpentinites and serpentinised peridotites from a range of geotectonic settings. ► Serpentinites appear to record the halogen composition of serpentinising fluids. ► Forearc serpentinites contain up to 45 ppm I and show extreme I/Cl enrichment. ► Serpentinites may dominate the deep subduction cycles of I, Br and noble gases.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Subduction zone fluxes of halogens and noble gases in seafloor and forearc serpentinites","attachmentId":30643915,"attachmentType":"pdf","work_url":"https://www.academia.edu/2640374/Subduction_zone_fluxes_of_halogens_and_noble_gases_in_seafloor_and_forearc_serpentinites","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/2640374/Subduction_zone_fluxes_of_halogens_and_noble_gases_in_seafloor_and_forearc_serpentinites"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="7" data-entity-id="23430098" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/23430098/Geochemistry_of_Ocean_Floor_and_Fore_arc_Serpentinites_Constraints_on_the_Ultramafic_Input_to_Subduction_Zones">Geochemistry of Ocean Floor and Fore-arc Serpentinites: Constraints on the Ultramafic Input to Subduction Zones</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="45393333" href="https://jamescook.academia.edu/CarlSpandler">Carl Spandler</a><span>, </span><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="329350578" href="https://independent.academia.edu/J%C3%A1nosKodol%C3%A1nyi">János Kodolányi</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Journal of Petrology, 2012</p><p class="ds-related-work--abstract ds2-5-body-sm">We provide new insights into the geochemistry of serpentinites from mid-ocean ridges (Mid-Atlantic Ridge and Hess Deep), passive margins (Iberia Abyssal Plain and Newfoundland) and fore-arcs (Mariana and Guatemala) based on bulk-rock and in situ mineral major and trace element compositional data collected on drill cores from the Deep Sea Drilling Project and Ocean Drilling Program. These data are important for constraining the serpentinite-hosted trace element inventory of subduction zones. Bulk serpentinites show up to several orders of magnitude enrichments in Cl, B, Sr, U, Sb, Pb, Rb, Cs and Li relative to elements of similar compatibility during mantle melting, which correspond to the highest primitive mantle-normalized B/Nb, B/Th, U/Th, Sb/Ce, Sr/Nd and Li/Y among subducted lithologies of the oceanic lithosphere (serpentinites, sediments and altered igneous oceanic crust). Among the elements showing relative enrichment, Cl and B are by far the most abundant with bulk concentrations mostly above 1000 mg g À1 and 30 mg g À1 , respectively. All other trace elements showing relative enrichments are generally present in low concentrations (mg g À1 level), except Sr in carbonate-bearing serpentinites (thousands of mg g À1 ). In situ data indicate that concentrations of Cl, B, Sr, U, Sb, Rb and Cs are, and that of Li can be, increased by serpentinization. These elements are largely hosted in serpentine (lizardite and chrysotile, but not antigorite). Aragonite precipitation leads to significant enrichments in Sr, U and B, whereas calcite is important only as an Sr host. Commonly observed brucite is trace element-poor.The overall enrichment patterns are comparable among serpentinites from mid-ocean ridges, passive margins and fore-arcs, whereas the extents of enrichments are often specific to the geodynamic setting. Variability in relative trace element enrichments within a specific setting (and locality) can be several orders of magnitude. Mid-ocean ridge serpentinites often show pronounced bulk-rock U enrichment in addition to ubiquitous Cl, B and Sr enrichment. They also exhibit positive Eu anomalies on chondrite-normalized rare earth element plots. Passive margin serpentinites tend to have higher overall incompatible trace element contents than mid-ocean ridge and fore-arc serpentinites and show the highest B enrichment among all the studied serpentinites. Fore-arc serpentinites are characterized by low overall trace element contents and show the lowest Cl, but the highest Rb, Cs and Sr enrichments. Based on our data, subducted dehydrating serpentinites are likely to release fluids with high B/Nb, B/Th, U/Th, Sb/Ce and Sr/Nd, rendering them one of the potential sources of some of the characteristic trace element fingerprints of arc magmas (e.g. high B/Nb, high Sr/Nd, high Sb/Ce). However, although serpentinites are a substantial part of global subduction zone chemical cycling, owing to their low overall trace element contents (except for B and Cl) their geochemical imprint on arc magma sources (apart from addition of H 2 O, B and Cl) can be masked considerably by the trace element signal from subducted crustal components.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Geochemistry of Ocean Floor and Fore-arc Serpentinites: Constraints on the Ultramafic Input to Subduction Zones","attachmentId":43871558,"attachmentType":"pdf","work_url":"https://www.academia.edu/23430098/Geochemistry_of_Ocean_Floor_and_Fore_arc_Serpentinites_Constraints_on_the_Ultramafic_Input_to_Subduction_Zones","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/23430098/Geochemistry_of_Ocean_Floor_and_Fore_arc_Serpentinites_Constraints_on_the_Ultramafic_Input_to_Subduction_Zones"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="8" data-entity-id="123900567" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/123900567/Geochemical_tracers_of_fluid_rock_interactions_in_exhumed_mantle_domains_a_comprehensive_study_of_serpentinization_processes_from_field_to_experiments">Geochemical tracers of fluid-rock interactions in exhumed mantle domains : a comprehensive study of serpentinization processes, from field to experiments</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="82890085" href="https://unistra.academia.edu/FloraHochscheid">Flora Hochscheid</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2022</p><p class="ds-related-work--abstract ds2-5-body-sm">cette thèse n'aurait pas vu le jour.

In order to constrain geochemical behavior of fluid-mobile elements hosted by serpentine phases during subduction processes, we carried out a geochemical study (trace elements and Pb isotopes) of a series of serpentinites and cumulates from the accretionary wedge of Greater Caribbean (Cuba and Dominican Republic). The trace element compositions of the primary and alteration-related phases were analyzed in situ using LA-HR-ICP-MS techniques. The studied samples represent parts of the subducted proto-Atlantic oceanic lithosphere, which has experienced low to high grade metamorphism (greenschist to eclogite facies), before being exhumed; a subset of these samples were derived from the mantle wedge. This sampling provides the opportunity to trace the chemical mobility of fluid-mobile elements during prograde metamorphism along a cold geotherm in an oceanic subduction setting. Serpentinites display strong enrichment in fluid-mobile elements indicating extensive fluid-rock interaction. In situ analyses allow distinction of three types of serpentines related to the nature of primary minerals (olivine, ortho-or clinopyroxene). Compositions of subducted samples, especially in fluid-mobile elements, are relatively close to those of abyssal peridotites without noticeable evidence of mobility for trace elements during subduction-related prograde metamorphism, with the exception of B. This confirms that the observed enrichment results from seawater/peridotite interactions during residence time in the ocean. It also suggests that most mobile elements stored in serpentine minerals are immobile during subduction processes. A major consequence of this observation is that serpentine minerals are a good sink for mobile elements in subduction zones, until their dehydration. Additionally, Pb isotopes and over-enrichment in As-Sb in high-grade subducted serpentines (antigorite) suggest the contribution of a sedimentary component during a secondary hydration taking place at the lizardite/antigorite transition. We propose that this new serpentinization event, taking place at greater depth, results from mixing between sediments and serpentinites in the subduction channel. Mantle wedge serpentinites present imprints of hydrothermal fluids: they are B-rich but without strong enrichment in As and Sb, and show evidence for moderate contributions of a radiogenic Pb-component. This suggests that the fluids that produced the mantle wedge serpentinites derived from the dehydration of the oceanic crust, with moderate to no contribution of sediments. We posit that mantle wedge serpentinization took place around 20-25 km depth: at such depth and temperature conditions (T> 200°C), the subducted sediments still released their B-rich pore fluids while their structural water incorporated in hydrous minerals (phengite, lawsonite) remained stable. The existence of various potential reservoirs for fluid-mobile elements in subduction zone environments (subducted serpentinites, mantle wedge serpentinites, as well as subducted sediments and altered oceanic crust) that potentially release their fluids at different depths has strong implications for arc lava formation.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Behavior of fluid-mobile elements in serpentines from abyssal to subduction environments: Examples from Cuba and Dominican Republic","attachmentId":96120136,"attachmentType":"pdf","work_url":"https://www.academia.edu/93361961/Behavior_of_fluid_mobile_elements_in_serpentines_from_abyssal_to_subduction_environments_Examples_from_Cuba_and_Dominican_Republic","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/93361961/Behavior_of_fluid_mobile_elements_in_serpentines_from_abyssal_to_subduction_environments_Examples_from_Cuba_and_Dominican_Republic"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div></div></div><div class="ds-sticky-ctas--wrapper js-loswp-sticky-ctas hidden"><div class="ds-sticky-ctas--grid-container"><div class="ds-sticky-ctas--container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{"location":"continue-reading-button--sticky-ctas","attachmentId":98175359,"attachmentType":"pdf","workUrl":null}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{"location":"download-pdf-button--sticky-ctas","attachmentId":98175359,"attachmentType":"pdf","workUrl":null}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div><div class="ds-below-fold--grid-container"><div class="ds-work--container js-loswp-embedded-document"><div class="attachment_preview" data-attachment="Attachment_98175359" style="display: none"><div class="js-scribd-document-container"><div class="scribd--document-loading js-scribd-document-loader" style="display: block;"><img alt="Loading..." src="//a.academia-assets.com/images/loaders/paper-load.gif" /><p>Loading Preview</p></div></div><div style="text-align: center;"><div class="scribd--no-preview-alert js-preview-unavailable"><p>Sorry, preview is currently unavailable.
