Isotopic data have been used to argue that a rise in marine sulfate concentrations to &gt;10 mM during the GOE was followed by a sulfate reservoir ‘collapse’. However, carbonate δ³⁴S and δ¹³C values often reflect conditions specific to depositional setting and diagenetic alteration. To assess the relative importance of global vs<em>.</em> local/diagenetic controls, we present δ³⁴S, δ²⁶Mg, δ^44/40Ca, and trace-metal data coupled with existing δ¹³C data from the ca. 2.1–2.0 Ga Tulomozero Formation and the overlying Zaonega Formation in the Onega Basin (Karelia, Russia). Over this transitional interval, δ³⁴S and Sr/(Ca+Mg) values increase whereas δ¹³C and δ^44/40Ca values decrease. X-ray absorption spectroscopy shows that the dominant form of sulfur within the rocks concomitantly shifted from mineralized sulfate and carbonate-associated sulfate (CAS) to variable mixtures of sulfide, sulfonate, and CAS. Those changes are associated with a depositional shift from shallow-marine to deeper-marine slope settings. δ^44/40Ca and Sr/(Ca+Mg) data indicate that depositional environmental changes drove a shift from seawater- to sediment-buffered carbonate recrystallization. Consequently, we interpret δ³⁴S trends that closely match those reported by previous workers as reflecting changing local environmental and diagenetic conditions, a finding that renders equivocal the use of such trends to assess sulfur cycle changes following the GOE. Our work establishes a blueprint for how to obtain deeper insight into the evolution of Earth's surface oxidation from stable isotope records.</div></div>","PeriodicalId":11481,"journal":{"name":"Earth and Planetary Science Letters","volume":"648 ","pages":"Article 119113"},"PeriodicalIF":4.8,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142660317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This water is likely not entrained by plumes but is instead captured by background mantle flow before returning to the mid-ocean ridges.

We propose that Earth accreted a few of these CC embryos while Mars did not, and that at least one of the CC embryos impacted Earth relatively late (when accretion was 90–98% complete).

Here we report the results of a long-period magnetotelluric (MT) study conducted in two 300 km-long trench-parallel transects crossing the northern boundary of the PSW in the proximal backarc. We modeled the MT data using 3-D inversion, obtaining an electrical resistivity model of the continental crust and upper mantle up to a depth of ∼150 km. Our model shows a heterogeneous resistivity structure in the uppermost mantle, dominated by resistivities &gt;300 Ωm below the array of sites even within the PSW, and some low-resistivity zones (LRZs, &lt;10 Ωm) mainly at the edge of the array. Using petrophysical models, we estimated the mantle temperature, water content, melt fraction, and viscosity based on obtained resistivity values and a preexistent model of P-wave velocity (<em>Vp</em>) at 50 km and 100 km depth. These estimates suggest that the uppermost mantle within the PSW region is heterogeneous and dominated by high-viscosity blocks, compatible with the continental mantle lithosphere or even subducted slabs. Based on relatively hot and low-viscosity zones estimated in the periphery of LRZs, we interpret the presence of asthenospheric mantle in areas where LRZs coincide with relatively low <em>Vp</em>. According to this interpretation, asthenospheric upwelling in the study area at depths ≤150 km would be localized rather than ubiquitous over the interpreted extent for the PSW. Such localized asthenosphere upwelling processes in the past could explain the scattered distribution of Neogene basaltic lavas in the southern Patagonia backarc. The continental crust exhibits LRZs in the upper and lower crust.

Most studies use petrological information of volatile element diffusive equilibration in glass and crystals to infer a single value for the magma ascent rate for a given eruption, even though numerical volcano conduit simulations show that changes of velocity are expected during magma ascent. Here we integrate magma ascent conduit models with diffusion chronometry of volatiles in melt embayments and phenocrysts to obtain a more comprehensive understanding of magma ascent rates. We find that incorporating a more realistic boundary condition that depends on the magma ascent path with variable velocities gives time estimates that can be up to a factor of 7 longer than from the standard assumption of constant magma ascent rate. Therefore, previous magma ascent rates from diffusion chronometry of volatiles in crystals and melts with a fixed boundary condition may be significantly overestimated.

(2) The waning of the Tristan-Gough plume is indicated by a decreasing melt production rate and an increase in inter-volcano spacing.
