While 0.1 wt.% carbon may be reasonable for shallow serpentinite near the seafloor, it is excessive for deeper serpentinite, leading to overestimation of the carbon sink in serpentinite. The bulk carbon taken up by sepentinites has δ 13 C values around − 9‰ (using δ 13 C values of − 8‰ and − 10‰ for low- and high-temperature ...

Serpentinite dehydration was inferred to occur at 3.5 GPa and 620 °C in the hot subduction zone, 5.3 GPa and 600 °C in the intermediate subduction zone, and 6.0 GPa and 550 °C in the cold subduction zone (Figure 3b and Table 2). Because the serpentinite layer is in contact with oceanic crust, we assumed for simplicity that serpentinite ...

The serpentinite capability of recording multiple interaction events with external fluids, as evidenced by increasing FME budgets and partial to complete reset of their isotopic signatures (Sr, Pb, O, Cl, B) makes this rock-type helpful to trace element recycling into the mantle and to unravel the evolution of exhumed HP–UHP terrains ...

In that spirit, I think some basic geologic facts are in order: • Firstly, "serpentine" refers to a group of minerals, not a rock. The term "serpentinite" is the proper term for the rock that is mostly made up of one or more of the serpentine group minerals. • Serpentinite is a metamorphosed version of rocks that make up oceanic ...

The core of the fibers may be empty or fi lled by amorphous matter. Chrysotile is poor in Al and total Fe and occurs mainly as a fi lling of fractures that crosscut serpentinite (FIG. 3C). Its parallel fiber orientation (cross, oblique, or slip) is mostly determined by the repeated opening of fractures (FIG. 3C).

Large serpentinite mud volcanoes form on the overriding plate of the Mariana subduction zone. Fluids from the descending plate hydrate (serpentinize) the forearc mantle and enable serpentinite muds to rise along faults to the seafloor. The seamounts are direct windows into subduction processes at depths far too deep to be accessed by any known …

Highlights. The role of serpentinites in various tectonic settings is reviewed. Serpentinite is a weak rock that localizes deformation in lithospheric shear zones. In oceanic domains, mantle is exhumed along serpentinized fault zones. Serpentinized layers at the subduction interface favour stagnant wedge corner.

Serpentinite is a metamorphic rock that forms at tectonic plate boundaries deep within the Earth. In the Franciscan Complex, it formed when ocean water carried down with subducting ocean crust was heated and moved through upper mantle and basal ocean crust rocks, hydrating their magnesium- and iron-rich minerals, like olive and pyroxene, …

Serpentinization denotes the hydrous alteration of olivine-rich ultramafic rocks, which can occur everywhere, where these rocks and aqueous solutions react under suitable pressure and temperature conditions. In the oceanic realm, seawater-derived fluids are abundant; however, ultramafic rocks (peridotites) are typically found in the Earth's ...

Serpentinite-hosted dolomite (ophidolomite) and magnesite (i.e. ophimagnesite, talc-magnesite rocks and listvenite) assemblages require higher aCO 2,aq and Mg/Ca ratios than those of seawater hydrothermal systems (cf. figure 6b of Grozeva et al., 2017) and, consequently, are uncommon in seafloor serpentinites (Eickmann, Bach, & Peckmann, …

2. Serpentinite origin of life. Viable ecological niches are formed by the reaction of hydrothermal sea water with mantle rocks to form serpentinites and the subsequent reaction of the vent fluids with CO 2-bearing sea water.Lane et al.[] and Russell et al[] were geologically explicit: life originated around alkaline (pH 9–11) vents from …

The development of talc-rich serpentinite and hybrid rock assemblages in the NE portion of the complex has been attributed to high fluid flux-driven metasomatism at depth (Spandler et al., 2008). Moreover, significant fluid fluxing is evident in the major element geochemistry for these serpentinite samples, ...

1. Introduction. Serpentinite-hosted hydrothermal systems are ideal places for abiotic synthesis of organic compounds, both gaseous and condensed, generally having low molecular weight (McCollom and Seewald, 2013, Menéz et al., 2018).In addition, serpentinite systems favour the formation of a number of redox-sensitive minerals, such …

Serpentinite is commonly found along fault zones, emplaced by "protrusion" of solid masses of the rock, rather than as hot igneous intrusions. In places where such serpentinite is exposed on top of hills, geologists have interpreted that some of the serpentinite later flowed downslope, not as landslides but like debris flows or lava flows.
