We use the triple oxygen isotope composition (O-17/O-16, O-18/O-16) of Proterozoic rocks to reconstruct the O-18/O-16 ratio of ancient meteoric waters. Some of these waters have originated from snowball Earth glaciers and thus give insight into the climate and hydrology of these critical intervals in Earth history. For a Paleoproterozoic [similar to 2.3-2.4 gigayears ago (Ga)] snowball Earth, delta O-18 = -43 +/- 3 parts per thousand is estimated for pristine meteoric waters that precipitated at low paleo-latitudes (<= 35 degrees N). Today, such low O-18/O-16 values are only observed in central Antarctica, where long distillation trajectories in combination with low condensation temperatures promote extreme O-18 depletion. For a Neoproterozoic (similar to 0.6-0.7 Ga) snowball Earth, higher meltwater delta O-18 estimates of -21 +/- 3% imply less extreme climate conditions at similar paleolatitudes (<= 35 degrees N). Both estimates are single snapshots of ancient water samples and may not represent peak snowball Earth conditions. We demonstrate how O-17/O-16 measurements provide information beyond traditional O-18/O-16 measurements, even though all fractionation processes are purely mass dependent."],["dc.identifier.doi","10.1073/pnas.1422887112"],["dc.identifier.isi","000353554000040"],["dc.identifier.pmid","25870269"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/37341"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","0027-8424"],["dc.title","Revealing the climate of snowball Earth from Delta O-17 systematics of hydrothermal rocks"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

This includes asteroids that are not otherwise represented in our meteorite collections. In this work we obtained 3D images of micrometeorite interiors using tomography before collecting destructive high-precision oxygen isotope measurements. These data allow us to link textures in unmelted micrometeorites to known chondrite groups. In addition to identifying particles from ordinary chondrites, CR and CM chondrites we report two micrometeorites derived from an anomalous 16O-poor source (δ17O: +16.4‰, δ18O: +28.4‰, and Δ17O: +1.4‰). Their compositions overlap with a previously reported micrometeorite (TAM50-25) from Suttle et al. (2020), https://doi.org/10.1016/j.epsl.2020.116444 (EPSL: 546:116444). These particles represent hydrated carbonaceous chondrite material derived either from a new group or from the CY chondrites (thereby extending the isotopic range of this group). In either scenario they demonstrate close petrographic and isotopic connections to the CO-CM chondrite clan. Furthermore, their position in O-isotope space makes them the most likely candidate for the parent body of the anomalous “group 4” cosmic spherules previously reported by Suavet et al. (2010), https://doi.org/10.1016/j.epsl.2010.02.046 (EPSL: 293:313-320) and several subsequent isotopic studies.

These rocks are important because aragonite of mantle origin has been reported as inclusion in olivine macrocrysts. We use petrographic observations, mineral compositions, as well as oxygen and carbon isotope ratios coupled with experimental petrology to understand the origin of carbonate phase in these olivine-phyric rocks. Groundmass and macrocryst olivines range from delta O-18(VSMOW) of + 4.8 parts per thousand, typical of mantle olivine values, to + 7.4 parts per thousand, indicating contamination by sedimentary carbonate. Carbonates are characterized by heavy oxygen isotope compositions (delta O-18(VSMOW) >+ 24 parts per thousand), and relatively light carbon isotopes (delta(CPDB)-C-13 < -11 parts per thousand), resembling skarn values, and distinct from typical mantle carbonatite compositions. Petrography, mineral compositions such as low Mg# of clinopyroxene and biotite, low Ca# and low incompatible element abundance of the carbonate, and isotopic ratios of O and C, do not support a mantle origin for the carbonate. Rather, the carbonate inclusions found in the olivine macrocrysts are interpreted as basement limestone fragments entrapped by the rising crystallizing magma. Comparison with experimental carbonatitic and silicate-carbonatitic melts indicates that low-degree partial melts of a carbonated peridotite must have a dolomitic rather than the aragonitic/calcitic composition as those found trapped in the Morron de Villamayor olivine macrocrysts.

The silicate melt-H2O vapor exchange experiments were carried out in a vertical gas-mixing furnace using the metal loop technique at 1500 degrees C. The duration ranged from 5 to 1440 min and fO(2) was set between IW - 3.8 and IW - 1.3 using the H2O/H-2 buffer. Our experiments show that 50% exchange between H2O gas and silicate melt occurs in similar to 4 h at fO(2) = IW -3.8 and in similar to 1 h at fO(2) = IW - 1.3. At solar nebula conditions, significant exchange occurs only if chondrule-melting times were several hours. (C) 2015 Elsevier Ltd.
