title: Enhanced weathering triggered the transient oxygenation event at ~1.57 Ga

description: The mid-Proterozoic (~1.8–0.8 Ga) is characterized by low atmospheric oxygen and pervasive oceanic anoxia, with transient oxygenations. One of the prominent oxygenation events happened at ~1.57 Ga, during which atmospheric O2 may have reached ≥4% present atmospheric level (PAL) and thus promoted the evolution of multi-cellular eukaryotes. The causes for this oxygenation event, however, remained unknown. Here, we report the result of δ202Hg and ∆199Hg, P concentration, Rb/Al, and Nd(t) across this oxygenation interval in the Gaoyuzhuang Formation of North China. The positive δ202Hg, Nd(t), and negative Δ199Hg shifts, and the accompanied peaks in Rb/Al, P and I/(Ca+Mg) suggest that this oxygenation was likely resulted from enhanced weathering of intermediate to mafic rocks, which may have promoted primary production via increasing P influx to the ocean and led to the rise in oxygen levels. The data indicate that enhanced weathering input can trigger transient oxygenation events during the mid-Proterozoic.

title: High water content of arc magmas recorded in cumulates from subduction zone lower crust

description: We report secondary ion mass spectrometry measurements of volatile (H2O, F, P, S, Cl) abundances in lower-crustal cumulate minerals from the Kohistan paleo-arc (NW Pakistan), and determine H2O abundances of melts from which the cumulates crystallized. Pyroxenes retained magmatic H2O abundances and record damp (less than 1% wt.% H2O) to hydrous (up to 10 wt.% H2O) primitive melts. Subsequent crystal fractionation led to formation of super-hydrous melts with approximately 12–20 wt.% H2O, predicted petrologically yet virtually absent from the melt inclusion record. Porphyry copper deposits are likely a natural eventuality of fluid exsolution from super-hydrous melts, corroborating a growing body of evidence.

title: Stability and seasonality: An ultrahigh resolution comparison of the dissolved organic matter composition between the world's two largest rivers, the Amazon and the Congo

description: This dataset contains geographic information, DOC concentrations, and DOM properties of water samples collected from the Amazon and Congo Rivers. The Amazon River was sampled near monthly from July 2011-November 2013 and the Congo River was sampled from September 2009-November 2010 from gauging stations near the outflow of each river. Samples were taken to study the seasonal properties of each river and how they compare in terms of molecular-level DOM composition as well as annual export. This dataset also contains FT-CIR MS peak lists for subsets that include mass peaks common in all samples, peaks unique to only Congo River samples, and peaks unique to only Amazon River samples. Portions of the Amazon River dataset have been previously published in a manuscript (https://doi.org/10.1029/2021GB006938) and archived in a repository (doi:10.26022/IEDA/111816).

title: Chondritic mercury isotopic composition of Earth and evidence for evaporative equilibrium degassing during the formation of eucrites

description: Mercury isotopes were measured in a suite of terrestrial lavas, including basaltic, trachytic, and granitic igneous lavas. Hg isotopes are also presented on a suite of chondritic meteorites and eucrite meteorites. The Hg isotopes in terrestrial samples are used to estimate the Hg isotope composition of the silicate Earth. The eucrites exhibit negative MIF (mass independently fractionated) for the odd-numbered Hg isotopes (199Hg and 201Hg). For the same odd-numbered isotopes, carbonaceous chondrites have positive MIF, ordinary chondrites have no MIF, and enstatite chondrites have positive MIF. Critically, the terrestrial igneous rocks have MIF and mass dependently fractionated isotopes that fall in the range defined by chondrites.

title: The Mercury Isotopic Composition of Earth's Mantle and the Use of Mass Independently Fractionated Hg to Test for Recycled Crust

description: Mercury isotopes were measured in a suite of well-characterized (for Sr-Nd-Pb-Hf isotopes) ocean island basalts from Tubuai, Pitcairn, Samoa, and Iceland. Lavas from the Afar hotspot were also examined. The data show that ocean island basalts exhibit both mass-dependent fractionation of Hg isotopes. Critically, the data reveal mass independently fractionated (MIF) Hg isotopes in OIB, from Samoa (negative MIF), Pitcairn (negative MIF), and Tubuai (positive MIF). These data suggest that Hg from surface reservoirs was recycled in the mantle sources of ocean island basalts.

title: “Missing links” for the long-lived Macdonald and Arago hotspots, South Pacific Ocean

description: The goal of this study is to characterize a suite of lavas from an atoll and several seamounts located between Samoa and the Cook Islands. These are volcanic features thought to result from the passage of the Pacific plate over two different hotspots, Macdonald hotspot and Arago-Rurutu hotspot. Ages from the atoll (Rose atoll) are consistent with an origin over the Arago-Rurutu hotspot, while ages from one of the seamounts (Moki seamount) are consistent with an origin over the Macdonald hotspot. The other seamounts do not have material appropriate for age-dating, but they have radiogenic isotopic signatures consistent with an origin over either the Arago-Rurutu or Moki seamounts.

title: Ancient helium and tungsten isotopic signatures preserved in mantle domains least modified by crustal recycling

description: The goal of this study is to characterize a suite of mid-Miocene Icelandic lavas that exhibit extremely high 3He/4He (up to 43 Ra, ratio to atmosphere). Whole rock radiogenic isotopes (i.e., long-lived radiogenic isotopes of Sr, Nd, Pb and Hf) were measured, as were whole rock major and trace element concentrations. 182W isotopic compositions were reported for one high 3He/4He Icelandic lava, and an anomalous composition is reported. The new geochemical dataset is placed in the context of geochemically characterized ocean island basalt lavas for which 182W has been measured. The study reports that lavas with high 3He/4He and anomalous 182W are found in ocean island basalts with the weakest signatures associated with crustal recycling.
